Análise configuracional dos grandes conjuntos urbanos na Região de Lisboa (1945-1974) : contributos da sintaxe espacial para a história de arte como história da cidade

A presente investigação debruça-se sobre o estudo dos grandes conjuntos urbanos, tendo como referência a área de Lisboa no período entre 1945 e 1974. O seu objetivo principal é compreender o padrão espacial e respetivas variantes destas formas urbanas relativamente recentes bem como avaliar o seu impato na estrutura global da cidade e da sociedade. Tomando como ponto de partida a história de arte como história da cidade, a tese toma como objeto o grande conjunto urbano e aponta a hipótese do estudo da relação forma-fundo como meio de obter informações relevantes que relacionem o uso e função com respeito ao desenho do espaço aberto. Como diferentes arranjos entre espaços abertos e fechados implicam tipos espaciais distintos (Medeiros 2013), o estudo da relação entre a forma (cheio) e o fundo (vazio) dos grandes conjuntos urbanos e respetivas variações, pode fornecer-nos informação espacial relevante, que nos permitem compreender melhor estas formas urbanas recentes. Usando a abordagem própria da teoria da sintaxe espacial (Hillier e Hanson 1984), do tipo configuracional, determinam-se as relações entre os vários elementos constituintes dos sistemas espaciais formados nestas urbanizações. Essas relações são depois analisadas através de medidas e variáveis topológicas que nos permitem identificar qualidades e valores espaciais para a sociedade. Os resultados obtidos a partir dessas variáveis e medidas permitem-nos, depois, avaliar os graus de ‘formalidade’ e ‘urbanidade’ em cada sistema (Holanda 2002). Consequentemente, a avaliação qualitativa das características espaciais que se pretendem obter nesta investigação, tem como base a avaliação quantitativa, permitindo assim comparar mais facilmente os diversos casos de estudo. De entre o conjunto de casos analisados, o estudo revela uma série de características comuns, que nos permitem identificar um padrão específico de urbanismo modernista que reflete claramente um conjunto de ideologias associadas a uma visão reformista da sociedade através do espaço. Mas por outro lado, existem também um conjunto de características particulares de cada caso, que reportam para a estrutura morfológica da cidade tradicional. No que reporta à hipótese de estudo levantada nesta investigação sobre a relação forma-fundo, verifica-se através da amostra que esta relação aparece invertida. Esta diferenciação deve-se ao abandono dos tradicionais sistemas de rua e de quarteirão, ainda presentes nas urbanizações de Alvalade e do Areeiro e a sua substituição pelo bloco livre em espaço aberto como nos casos de Alfragide, Portela e Olivais. Tal facto, como prova a teoria da Sintaxe Espacial ou Lógica Social do Espaço, traduziu-se necessariamente em diferentes modos de vida pública e privada e consequentemente de vida espacial e social. Assim concluímos, através da análise dos casos de estudo apresentados, que embora fazendo parte duma mesma ideologia urbana com características comuns (genótipo modernista), os mesmos apresentam resultados espaciais totalmente diferenciados o que justifica a dificuldade da sua análise comparativa.

The role of arl13b in cilia length regulation and in zebrafish development

RESUMO: Arl13b é uma importante proteína ciliar, presente em cílios primários e cílios móveis. Ratinhos mutantes para Arl13b têm comprimento dos cílios reduzido e defeitos nos B-túbulos dos cílios. Como consequência destes fenótipos, deficiências na Arl13b originam, em modelos animais, várias doenças congénitas, incluindo problemas no estabelecimento do eixo esquerda-direita, malformações cerebrais e deformações corporais. Nos seres humanos, deficiências na Arl13b levam a uma doença crónica congénita chamada Síndrome de Joubert. Por outro lado, a sobreexpressão de Arl13b origina cílios mais longos, no entanto existe uma ausência da caracterização dos fenótipos celulares e durante o desenvolvimento embrionário. Neste trabalho, quisemos explorar o efeito da sobre-expressão de Arl13b em embriões de peixezebra. Descobrimos que, ao nível ciliar, a sobre-expressão de Arl13b nas células aumenta o comprimento ciliar em cílios primários e móveis, no entanto, a esses cílios falta adequada acetilação da alfa-tubulina no citoesqueleto feito por microtúbulos. Os nossos resultados mostraram que esse efeito é específico de Arl13b sobre-expressão e quando se manipularam as enzimas responsáveis pela acetilação (Mec17) e pela de-acetilação (HDAC6) encontrámos uma sinergia potencial com ambas. Testámos ainda, que o aumento no comprimento ciliar não estava causalmente relacionado com a falta de acetilação, ou seja, os cílios com menos acetilação não eram necessariamente os mais longos. Também mostrámos que a sobre-expressão de Arl13b é capaz de restaurar o comprimento dos cílios em mutantes com cílios curtos e como isso pode ser explorado para um futuro potencial papel terapêutico para Arl13b. Em seguida, foi avaliado o impacto do aumento da quantidade de Arl13b no desenvolvimento embrionário do peixe-zebra. Observou-se que a sobre-expressão de Arl13b apresentava fenótipos muito fracos, quando comparados com a perda de função dos mutantes de Arl13b. Focados no inesperado fenótipo leve no estabelecimento do eixo esquerda-direita abordámos a questão através do estabelecimento de uma colaboração com matemáticos, descobrimos que os cílios mais longos que potencialmente têm a capacidade de movimentar mais fluido são atenuados por amplitudes de batimento menores, e, como resultado, estes longos cílios não prejudicam o movimento do fluido e consequentemente não afetam o estabelecimento dos padrões de esquerda-direita. Sugerimos assim que a Arl13b é um regulador chave, do comprimento ciliar. Descobrimos uma nova interação com as enzimas de acetilação/de-acetilação e levantamos novas hipóteses quanto aos mecanismos moleculares da função da Arl13b. Propomos um novo modelo para o mecanismo molecular da Arl13b na regulação do comprimento dos cílios onde podemos integrar os nossos resultados com os relatados na literatura. Este trabalho adiciona mais conhecimento para o mecanismo de ação da Arl13b e, portanto, fornece uma importante contribuição para o campo da investigação em cílios.---------------------------------------------------------------------------------------------------------------------- ABSTRACT: Arl13b is an important ciliary protein, present in primary and motile cilia. arl13b-/- mouse mutants have reduced cilia length and cilia B-tubule defects. As a consequence of these phenotypes, Arl13b loss of function animal models suffer from several congenital disorders including left-right problems, brain malformations and body deformations. In humans Arl13b depletion leads to a congenital chronic disease called Joubert Syndrome. On the other hand, overexpressing Arl13b leads to longer cilia but the characterization of the cellular and developmental phenotypes was missing. In this work we explore the effect of Arl13b overexpression in zebrafish embryos. We found that, at the ciliary level, Arl13b overexpression from 1 cell stage produces longer primary and motile cilia, but these cilia lack proper alpha tubulin acetylation of their microtubule cytoskeleton. Our results showed that this effect is specific from Arl13b overexpression and when we manipulated the enzymes responsible for acetylation, Mec17, and de-acetylation, HDAC6, we found a potential synergy of both mec17 knockdown and HDAC6 activity with Arl13b overexpression. We tested that the ciliary increase in length was not causally related to the lack of acetylation, meaning the more de-acetylated cilia were not necessarily the longer ones. We also showed that Arl13b overexpression is able to restore cilia length in short cilia mutants and how that may be explored to a potential future therapeutic role for Arl13b. Next, we evaluated the impact of increasing the amount of Arl13b in zebrafish embryonic development. We observed that Arl13b overexpression presented very mild phenotypes when compared to the loss of function mutants. We focused on the unexpected left-right mild phenotype and by establishing a mathematical modeling collaboration, we found out that the longer cilia generated force was attenuated by smaller beating amplitudes, and as a result, these long cilia were not impairing the cilia generated flow and the establishment of left-right patterning. We suggest that Arl13b is one key cilia length regulator. We disclosed a novel interaction with the acetylation / de-acetylation enzymes and raised new hypothesis as to the mechanisms of Arl13b function. We propose a new model for the Arl13b molecular mechanism of cilia length regulation where we integrate our findings with those reported in the literature. This work adds more knowledge to the Arl13b mechanism of action and therefore provides an important contribution to the cilia research field.

Ashbya gossypii beyond industrial riboflavin production: a historical perspective and emerging biotechnological applications

The filamentous fungus Ashbya gossypii has been safely and successfully used for more than two decades in the commercial production of riboflavin (vitamin B2). Its industrial relevance combined with its high genetic similarity with Saccharomyces cerevisiae together promoted the accumulation of fundamental knowledge that has been efficiently converted into a significant molecular and in silico toolbox for its genetic engineering. This synergy has enabled a directed and sustained exploitation of A. gossypii as an industrial riboflavin producer. Although there is still room for optimizing riboflavin production, the recent years have seen an abundant advance in the exploration of A. gossypii for other biotechnological applications, such as the production of recombinant proteins, single cell oil and flavour compounds. Here, we will address the biotechnological potential of A. gossypii beyond riboflavin production by presenting (a) a physiological and metabolic perspective over this fungus; (b) the molecular toolbox available for its manipulation; and (c) commercial and emerging biotechnological applications for this industrially important fungus, together with the approaches adopted for its engineering.

Embedding, evolution, and validation of model-driven spreadsheets

This paper proposes and validates a model-driven software engineering technique for spreadsheets. The technique that we envision builds on the embedding of spreadsheet models under a widely used spreadsheet system. This means that we enable the creation and evolution of spreadsheet models under a spreadsheet system. More precisely, we embed ClassSheets, a visual language with a syntax similar to the one offered by common spreadsheets, that was created with the aim of specifying spreadsheets. Our embedding allows models and their conforming instances to be developed under the same environment. In practice, this convenient environment enhances evolution steps at the model level while the corresponding instance is automatically co-evolved.Finally,wehave designed and conducted an empirical study with human users in order to assess our technique in production environments. The results of this study are promising and suggest that productivity gains are realizable under our model-driven spreadsheet development setting.

Production and extraction of polysaccharides and oligosaccharides and their use as new food additives

Polysaccharides and oligosaccharides can improve quality and enhance nutritional value of final food products due to their technological and nutritional features ranging from their capacity to improve texture to their effect as dietary fibers. For this reason, they are among the most studied ingredients in the food industry. The use of natural polysaccharides and oligosaccharides as food additives has been a reality since the food industry understood their potential technological and nutritional applications. Currently, the replacement of traditional ingredients and/or the synergy between traditional ingredients and polysaccharides and oligosaccharides are perceived as promising approaches by the food industry. Traditionally, polysaccharides have been used as thickening, emulsifying, and stabilizing agents, however, at this moment polysaccharides and oligosaccharides claim health and nutritional advantages, thus opening a new market of nutritional and functional foods. Indeed, their use as nutritional food ingredients enabled the food industry to develop a countless number of applications, e.g., fat replacers, prebiotics, dietary fiber, and antiulcer agents. Based on this, among the scientific community and food industry, in the last years many research studies and commercial products showed the possibility of using either new or already used sources (though with changed properties) of polysaccharides for the production of food additives with new and enhanced properties. The increasing interest in such products is clearly illustrated by the market figures and consumption trends. As an example, the sole market of hydrocolloids is estimated to reach $7 billion in 2018. Moreover, oligosaccharides can be found in more than 500 food products resulting in a significant daily consumption. A recent study from the Transparency Market Research on Prebiotic Ingredients Market reported that prebiotics' demand was worth $2.3 billion in 2012 and it is estimated to reach $4.5 billion in 2018, growing at a compound annual growth rate of 11.4% between 2012 and 2018. The entrance of this new generation of food additives in the market, often claiming health and nutritional benefits, imposes an impartial analysis by the legal authorities regarding the accomplishment of requirements that have been established for introducing novel ingredients/food, including new poly- and oligosaccharides. This chapter deals with the potential use of polysaccharides and oligosaccharides as food additives, as well as alternative sources of these compounds and their possible applications in food products. Moreover, the regulation process to introduce novel polysaccharides and oligosaccharides in the market as food additives and to assign them health claims is discussed.

Modulación de la activación de células dendríticas por antígenos de Fasciola hepatica y ligandos para receptores Toll: Potencial terapéutico en respuestas anti-inflamatorias. Fasciola hepatica antigens and TLR ligands modulate dendritic cells activation: therapeutic potential in anti-inflammatory responses.

Antecedentes: En nuestro laboratorio hemos demostrado que antígenos (Ags) de Fasciola hepatica inducen en células dendríticas murinas (CD), diferentes propiedades tolerogénicas como la incapacidad por si mismos de inducir la maduración de las células, la resistencia a la maduración por ligandos de TLR, el incremento en la producción de IDO y también la capacidad de esta estas células de dirigir la respuesta inmune hacia un perfil Th2 y T reg. Por otra parte ha sido bien documentado que CD con características tolerogénicas, ya sea inmaduras o semimaduras, son útiles para reducir respuestas inflamatorias excesivas tales como las que ocurren en enfermedades autoinmunes. Además hemos demostrado que CD tratadas con Ags del parásito en conjunto con un ligando Toll (CpG-ODN) producen altos niveles de citoquinas anti-inflamatorias (IL-10 y TGF-) bajos de citoquinas proinflamatorias (TNF, IL-6, IL-12). Hipótesis: El fenotipo semimaduro alcanzado en las CDpodría ser utilizado para reducir la inflamación en un modelo de enfermedad autoinmune en donde existe una exacerbada respuesta Th1 y Th17, ya que la producción elevada de IL-10 y TGF- podría inhibir o controlar estas respuestas de manera directa o a través de la inducción de células T regulatorias. Objetivos: En este proyecto nosotros proponemos la inmunización de animales susceptibles (ratones DBA1/j), al desarrollo de artritis inducida por colágeno (AIC) con CD tratadas con Ags de F. hepatica en conjunto con CpG-ODN para reducir los síntomas clínicos de la enfermedad. Materiales a utilizar: En nuestro laboratorio hemos desarrollado un modelo de artritis inducida por colágeno (AIC) mediante dos inmunizaciones de ratones DBA1/j con colágeno tipo II bovino y adyuvante de Freund. El modelo permitió establecer un índice clínico mediante la hinchazón en las patas de los animales. Doce días posteriores a la primera inmunización los animales serán inyectados con CD tratadas con: 1. PBS, 2.Extracto total de F.hepatica (TE) + CII, 3. CpG + CII, 4. TE+CpG+CII Se realizará la observación macroscópica diaria, a partir de los 7 días de la 2a inmunización Luego del sacrificio las articulaciones de las patas se prepararán para realizar un análisis histológico. Se detectará en suero los niveles de anticuerpos IgG1 (perfil Th2) y de IgG2a (perfil Th1) mediante la técnica de ELISA. Se detectará también el perfil de citoquinas en los nódulos drenantes por la técnica de ELISA y adicionalmente la poblaciónes celulares de células T regulatorias (Treg) CD4+CD25+Foxp3 o células Tr1. Resultados esperados: Pensamos que el tratamiento de los animales que desarrollan AIC con CD semimaduras (por el tratamiento con TE y CpG), serán capaces de migrar a los órganos linfaticos y secretar TGF-be(inductora de células T reg), IL-10 (inductoras de células Tr1), IDO inhibitoria de la respuesta de Li T y promotor de células T reg, también podría generarse una respuesta Th2 (por la presencia de antígenos del parásito), y estas respuestas aisladas o en forma sinérgica podrían inhibir las respuestas de tipo Th17 y Th1 asociadas a la patología en esta enfermedad. Importancia del proyecto: En el desarrollo de la artritis existe un aumento de la inmunidad mediada por células, asi como de la respuesta inmune humoral hacia componentes de la matriz del cartílago. El tratamiento convencional de la artritis recae en general en el uso de inmunosupresores no-específicos, los cuales poseen una variedad de efectos adversos y la inhibición de la respuesta inflamatoria no es específica. En este proyecto proponemos el uso de CD tratadas con antígenos del helminto F. hepatica y CpG ligando Tol que capacita a estas células para generar una respuesta adaptativa de tipo regulatoria, útil en la inhibición de las respuestas inflamatorias como la que ocurre durante la progresión de artritis reumatoidea en un modelo experimental en ratones. We have shown that F. hepatica Ags-treated dendritic cells (DC) together with a TLRl ligand (CpG-ODN) produce high levels of anti-inflammatory cytokines (IL-10 and TGF-Beta) and low of proinflammatory cytokines (TNF, IL-6, IL -12). Hypothesis: The semimature phenotype achieved by DC, could be used to reduce inflammation in a model of autoimmune disease. The high production of IL-10 and TGF-Beta by these cells could directly or through the induction of T reg cells inhibit the inflammatory response. Objective: In this project we propose the immunization of DBA1 / j mice, susceptible to the development of collagen-induced arthritis (CIA) with F. hepatica-treated DC in conjunction with CpG-ODN to reduce clinical signs of disease. Materials: In our laboratory, we developed the CIA model by two immunizations of DBA1 / j mice with bovine type II collagen and Freund's adjuvant. The model allowed to stablish a clinical index by swelling in the legs of animals. Twelve days after the first immunization the animals are injected with DC treated with: 1. PBS 2. F.hepatica Extract (TE) + CII, 3. CpG + CII, 4. TE + CpG + CII Macroscopic observation will take place daily from 7 days of the 2nd immunization. After sacrifice the joints of the legs will be prepared for histological analysis. Serum levels of IgG1 antibodies (Th2 profile) and IgG2a (Th1 profile) will be detected by ELISA. It will also detected the cytokine profile in draining lymph nodes by ELISA and additionally the cell populations of regulatory T cells (Treg) CD4 + CD25 + Foxp3 or Tr1 cells. Expected results: We believe that the treatment of animals that had developed CIA with DC will be able to migrate to lymphatic organs and secrete TGF-B (T reg cell-inducing), IL-10 (inducing Tr1 cells), IDO (inhibitory of T cells and inducing of T reg cells) could alone or in synergy inhibit Th17-type responses and Th1 associated with the pathology in this disease.

Valor do escore de calcio coronariano para prever a gravidade ou complexidade da doenca arterial coronariana

FUNDAMENTO: A previsão de gravidade ou complexidade da doença arterial coronariana (DAC) é valiosa devido ao aumento do risco de eventos cardiovasculares. Embora a associação entre o escore do cálcio arterial coronariano (CAC), e a gravidade da DAC pelo escore Gensini não tenha sido utilizado, já foi anteriormente demonstrado. Não há informações sobre a associação entre o escore do CAC total e a complexidade da DAC. OBJETIVOS: Investigar a associação entre a gravidade ou complexidade da doença arterial coronariana (DAC), avaliada pelo escore Gensini e SYNTAX (SS), respectivamente, e o escore do cálcio arterial coronariano (CAC), um método não invasivo para avaliação de DAC em pacientes sintomáticos com DAC significativa. MÉTODOS: Duzentos e quatorze pacientes foram incluídos. A pontuação total do CAC foi obtido antes da angiografia. A severidade e complexidade da DAC foram avaliadas pelo escore Gensini e SS, respectivamente. Foram analisadas as associações entre parâmetros clínicos e angiográficos e o escore total do CAC. RESULTADOS: A mediana do escore total do CAC foi de 192 (23,0-729,8), e correlacionou-se positivamente com ambos os escores Gensini (r: 0,299, p < 0,001) e ES (r: 0,577, p < 0,001). Na análise multivariada associou-se independentemente com a idade (ß: 0,154, p: 0,027), sexo masculino (ß: 0,126, p: 0,035) e ES (ß: 0,481, p < 0,001). A análise da curva ROC (Receiver Operating Characteristics) revelou um valor de corte > 809 para ES > 32 (tercil de SS alto). CONCLUSÃO: Em pacientes sintomáticos com DAC significativa, o escore total de CAC foi independentemente associado com SS e os pacientes com SS > 32 podem ser detectados através de escore Agatston alto.

The Sanctified ‘Adultress’ and Her Circumstantial Clause: Bathsheba’s Bath and Self-Consecration in 2 Samuel 11

Bathsheba's actions in 2 Sam. 11.2-4 identify crucial aspects of her character. Past commentators interpret these words in connection with menstrual purification, stressing the certain paternity of David's adulterine child. This article demonstrates that the participles rōheset and mitqaddesšet and the noun mittum'ātāh do not denote menstrual cleansing. Bathsheba's washing is an innocent bath. She is the only individual human to self-sanctify, placing her in the company of the Israelite deity. The syntax of the verse necessitates that her action of self-sanctifying occurs simultaneously as David lies with her. The three focal terms highlight the important legitimacy of Bathsheba before the Israelite deity, her identity as a non-Israelite, her role as queen mother of the Solomonic line, and her full participation in the narrative.

MART-1 peptide vaccination plus IMP321 (LAG-3Ig fusion protein) in patients receiving autologous PBMCs after lymphodepletion: results of a Phase I trial.

BACKGROUND: Immunotherapy offers a promising novel approach for the treatment of cancer and both adoptive T-cell transfer and immune modulation lead to regression of advanced melanoma. However, the potential synergy between these two strategies remains unclear. METHODS: We investigated in 12 patients with advanced stage IV melanoma the effect of multiple MART-1 analog peptide vaccinations with (n = 6) or without (n = 6) IMP321 (LAG-3Ig fusion protein) as an adjuvant in combination with lymphodepleting chemotherapy and adoptive transfer of autologous PBMCs at day (D) 0 (Trial registration No: NCT00324623). All patients were selected on the basis of ex vivo detectable MART-1-specific CD8 T-cell responses and immunized at D0, 8, 15, 22, 28, 52, and 74 post-reinfusion. RESULTS: After immunization, a significant expansion of MART-1-specific CD8 T cells was measured in 83% (n = 5/6) and 17% (n = 1/6) of patients from the IMP321 and control groups, respectively (P < 0.02). Compared to the control group, the mean fold increase of MART-1-specific CD8 T cells in the IMP321 group was respectively >2-, >4- and >6-fold higher at D15, D30 and D60 (P < 0.02). Long-lasting MART-1-specific CD8 T-cell responses were significantly associated with IMP321 (P < 0.02). At the peak of the response, MART-1-specific CD8 T cells contained higher proportions of effector (CCR7⁻ CD45RA⁺/⁻) cells in the IMP321 group (P < 0.02) and showed no sign of exhaustion (i.e. were mostly PD1⁻CD160⁻TIM3⁻LAG3⁻2B4⁺/⁻). Moreover, IMP321 was associated with a significantly reduced expansion of regulatory T cells (P < 0.04); consistently, we observed a negative correlation between the relative expansion of MART-1-specific CD8 T cells and of regulatory T cells. Finally, although there were no confirmed responses as per RECIST criteria, a transient, 30-day partial response was observed in a patient from the IMP321 group. CONCLUSIONS: Vaccination with IMP321 as an adjuvant in combination with lymphodepleting chemotherapy and adoptive transfer of autologous PBMCs induced more robust and durable cellular antitumor immune responses, supporting further development of IMP321 as an adjuvant for future immunotherapeutic strategies.

Compendium of projects in the European nanosafety cluster

This is the third edition of the compendium. It documents the status of important projects on nanomaterial toxicity and exposure monitoring, integrated risk management, research infrstructure and coordination and support activities. The compendium is not intended to be a guidance document for human health and environmental safety management of nanotechnologies, as such guidance documents already exist and are widely available. Neither is the compendium intended to be a medium for the publication of scientific papers and research results, as this task is covered by scientific conferences and the reviewed press. The compendium aims to bring researchers closer together and show them the potential for synergy in their work. It is a means to establish links and communication between them during the actual research phase and well before the publication of their results. It thus focuses on the communication of projects' strategic aims, extensively covers specific work objectives and the methods used in research, and documents human capacities and available laboratory infrastructure. As such, the compendium supports collaboration on common goals and the joint elaboration of future plans, whilst compromising neither the potential for scientific publication, nor intellectual property rights.

Looming signals reveal synergistic principles of multisensory integration.

Multisensory interactions are a fundamental feature of brain organization. Principles governing multisensory processing have been established by varying stimulus location, timing and efficacy independently. Determining whether and how such principles operate when stimuli vary dynamically in their perceived distance (as when looming/receding) provides an assay for synergy among the above principles and also means for linking multisensory interactions between rudimentary stimuli with higher-order signals used for communication and motor planning. Human participants indicated movement of looming or receding versus static stimuli that were visual, auditory, or multisensory combinations while 160-channel EEG was recorded. Multivariate EEG analyses and distributed source estimations were performed. Nonlinear interactions between looming signals were observed at early poststimulus latencies (∼75 ms) in analyses of voltage waveforms, global field power, and source estimations. These looming-specific interactions positively correlated with reaction time facilitation, providing direct links between neural and performance metrics of multisensory integration. Statistical analyses of source estimations identified looming-specific interactions within the right claustrum/insula extending inferiorly into the amygdala and also within the bilateral cuneus extending into the inferior and lateral occipital cortices. Multisensory effects common to all conditions, regardless of perceived distance and congruity, followed (∼115 ms) and manifested as faster transition between temporally stable brain networks (vs summed responses to unisensory conditions). We demonstrate the early-latency, synergistic interplay between existing principles of multisensory interactions. Such findings change the manner in which to model multisensory interactions at neural and behavioral/perceptual levels. We also provide neurophysiologic backing for the notion that looming signals receive preferential treatment during perception.
