Structural changes induced by daily music listening in the recovering brain after middle cerebral artery stroke: a voxel-based morphometry study

Music is a highly complex and versatile stimulus for the brain that engages many temporal, frontal, parietal, cerebellar, and subcortical areas involved in auditory, cognitive, emotional, and motor processing. Regular musical activities have been shown to effectively enhance the structure and function of many brain areas, making music a potential tool also in neurological rehabilitation. In our previous randomized controlled study, we found that listening to music on a daily basis can improve cognitive recovery and improve mood after an acute middle cerebral artery stroke. Extending this study, a voxel-based morphometry (VBM) analysis utilizing cost function masking was performed on the acute and 6-month post-stroke stage structural magnetic resonance imaging data of the patients (n = 49) who either listened to their favorite music [music group (MG), n = 16] or verbal material [audio book group (ABG), n = 18] or did not receive any listening material [control group (CG), n = 15] during the 6-month recovery period. Although all groups showed significant gray matter volume (GMV) increases from the acute to the 6-month stage, there was a specific network of frontal areas [left and right superior frontal gyrus (SFG), right medial SFG] and limbic areas [left ventral/subgenual anterior cingulate cortex (SACC) and right ventral striatum (VS)] in patients with left hemisphere damage in which the GMV increases were larger in the MG than in the ABG and in the CG. Moreover, the GM reorganization in the frontal areas correlated with enhanced recovery of verbal memory, focused attention, and language skills, whereas the GM reorganization in the SACC correlated with reduced negative mood. This study adds on previous results, showing that music listening after stroke not only enhances behavioral recovery, but also induces fine-grained neuroanatomical changes in the recovering brain.

Estudi per a un sistema de mesura de pes per a marmota alpina

Aquest projecte tracta sobre la viabilitat de la construcció d’un sistema per al seguiment del pes d’una població de marmotes en alta muntanya. Bàsicament, es construeix una bàscula amb un sensor de força i un sensor de temperatura. Aquestes sortides analògiques es connecten a un microcontrolador ATmega8 que, mitjançant un algorisme desenvolupat en aquest projecte, està contínuament en escolta fins a detectar un canvi sobtat en el pes. Aleshores les dades s’enregistren i es guarden en una memòria SRAM per a, posteriorment, poder ser descarregades a un ordinador i analitzades per un programa que s’ha creat per a tal finalitat.

8-month non-use of a language. A case tudy. A longitudinal study of the effects on non use of one of the languages (Spanish) of a German L1 multilingual

Under the Dynamic Model of Multilingualism multilinguals are especially vulnerable to language attrition. It was the aim of the present study to verify if this was the case and to observe whether the different linguistic skills (receptive vs. descriptive) and the different linguistic levels (syntactic, lexical, morphological, etc.) would be affected equally.Data were gathered longitudinally by means of a language test for the subject’s reading, writing, listening and speaking skills as well as her knowledge of grammar and vocabulary. Although the overall accuracy remained intact and no proof for attrition in the receptive skills was found, the productive skills - mainly fluency - were shown to have suffered from language attrition. This was demonstrated by an increase in the number of pauses, hesitations, repetitions and self-corrections among others and decrease in the percentage of error-free clauses and decrease in the clause length, in oral and written fluency respectively.

Chopin & Leopardi : dues sensibilitats bessones

Aquest treball vol estudiar les relacions que s'estableixen entre dos artistes d'un mateix període estètic: Frédéric Chopin i Giacomo Leopardi. Ho fa analitzant 7 parelles de música i poesia, analitzades per descobrir què és allò que les uneix. Després d'una reflexió al voltant de l'art, el treball reflexiona sobre què aporta a l'estudi d'un període artístic, d'unes determinades obres o a l'escolta d'un concert, la combinació de dues o més disciplines artístiques. Chopin & Leopardi: dues sensibilitats bessones, doncs, que acaben connectant també amb nosaltres, descobrint en l'art l'expressió de quelcom universal que uneix artista, intèrpret i públic.

La lectura compartida: una eina per l'aprenentatge de la lecto-escriptura en equips cooperatius

L’estudi de cas que es presenta l’hem realitzat a Cicle inicial (CI) de l’escola els Castanyers de Viladrau. Hem portat a terme un projecte per tal d’estudiar la lectura compartida tot utilitzant equips cooperatius (Pujolàs, 2008). Els objectius d’aquest treball són: en primer lloc, ensenyar els alumnes a aprendre de manera cooperativa, és a dir, saber treballar conjuntament, tenir respecte mutu, escoltar als companys, proporcionar ajudes a la resta de l’equip i respectar els punts de vista dels altres, i, en segon lloc, millorar la comprensió dels texts; millorar la lectura i l’escriptura, saber realitzar les tasques i rols, saber seleccionar informació, aprendre a realitzar preguntes. Per portar-lo a terme vam realitzar set sessions en les qual la lectura compartida i els equips cooperatius eren les bases de totes elles. El conjunts de les activitats ens ha permès evidenciar una cohesió del grup-classe més elevada que abans de realitzar-les, així com una lleugera millora en els aspectes relacionats amb la comprensió lectora.

Using music as a signal for biofeedback

Studies on the potential benefits of conveying biofeedback stimulus using a musical signal have appeared in recent years with the intent of harnessing the strong effects that music listening may have on subjects. While results are encouraging, the fundamental question has yet to be addressed, of how combined music and biofeedback compares to the already established use of either of these elements separately. This experiment, involving young adults (N = 24), compared the effectiveness at modulating participants' states of physiological arousal of each of the following conditions: A) listening to pre-recorded music, B) sonification biofeedback of the heart rate, and C) an algorithmically modulated musical feedback signal conveying the subject's heart rate. Our hypothesis was that each of the conditions (A), (B) and (C) would differ from the other two in the extent to which it enables participants to increase and decrease their state of physiological arousal, with (C) being more effective than (B), and both more than (A). Several physiological measures and qualitative responses were recorded and analyzed. Results show that using musical biofeedback allowed participants to modulate their state of physiological arousal at least equally well as sonification biofeedback, and much better than just listening to music, as reflected in their heart rate measurements, controlling for respiration-rate. Our findings indicate that the known effects of music in modulating arousal can therefore be beneficially harnessed when designing a biofeedback protocol.

Atypical language organization in temporal lobe epilepsy revealed by a passive semantic paradigm

Background Mesial temporal lobe epilepsy (MTLE) is the most common type of focal epilepsy in adults and can be successfully cured by surgery. One of the main complications of this surgery however is a decline in language abilities. The magnitude of this decline is related to the degree of language lateralization to the left hemisphere. Most fMRI paradigms used to determine language dominance in epileptic populations have used active language tasks. Sometimes, these paradigms are too complex and may result in patient underperformance. Only a few studies have used purely passive tasks, such as listening to standard speech. Methods In the present study we characterized language lateralization in patients with MTLE using a rapid and passive semantic language task. We used functional magnetic resonance imaging (fMRI) to study 23 patients [12 with Left (LMTLE), 11 with Right mesial temporal lobe epilepsy (RMTLE)] and 19 healthy right-handed controls using a 6 minute long semantic task in which subjects passively listened to groups of sentences (SEN) and pseudo sentences (PSEN). A lateralization index (LI) was computed using a priori regions of interest of the temporal lobe. Results The LI for the significant contrasts produced activations for all participants in both temporal lobes. 81.8% of RMTLE patients and 79% of healthy individuals had a bilateral language representation for this particular task. However, 50% of LMTLE patients presented an atypical right hemispheric dominance in the LI. More importantly, the degree of right lateralization in LMTLE patients was correlated with the age of epilepsy onset. Conclusions The simple, rapid, non-collaboration dependent, passive task described in this study, produces a robust activation in the temporal lobe in both patients and controls and is capable of illustrating a pattern of atypical language organization for LMTLE patients. Furthermore, we observed that the atypical right-lateralization patterns in LMTLE patients was associated to earlier age at epilepsy onset. These results are in line with the idea that early onset of epileptic activity is associated to larger neuroplastic changes.

Assessment in CLIL

The aim of this talk is to explore assessment in higher education and support for learners during their academic education. It investigates the assessment methods that provide success for universities and learners. Universities which implement CLIL should assess learners who would like to attend a programme in English without taking account of their English language qualifications. This assessment should be done in writing, listening and comprehension, speaking and reading and comprehension. In the literature, formative and summative assessments are considered. Formative assessment is ongoing, 'more complex as its intention is to be directly diagnostics with a view to immediately impacting on learner's next steps' (Coyle et al, 2010). Summative assessment occurs at the end of the term or course. McKay, 2006 divides assessment into three phases: design, operationalization and administration phase. If these three phases can't be embedded in the classroom as they are, they can be introduced as a set of questions; why?, how? and what?

Comunicación Terapéutica : Requisitos fundamentales para acompañar emocionalmente al paciente paliativo y su familia.

La comunicación entre los enfermeros y los pacientes oncológicos es fundamental en la construcción de la relación profesional y terapéutica y esencial para administrar unos cuidados realmente enfocados en la persona como ser holístico y no como entidad patológica. Diferentes estudios han demostrado la influencia positiva de la comunicación en la satisfacción del paciente e incluso se ha encontrado relación entre una comunicación efectiva y una mayor adherencia al tratamiento, mejor control del dolor y estado psicológico. La comunicación, como herramienta para establecer una relación terapéutica eficaz, a su vez básica para el cuidado de cualquier paciente, es entonces “la herramienta” y prerrequisito indispensable para cuidar estos pacientes desde una perspectiva holística. Pese a la centralidad en el cuidado enfermero, la comunicación no se emplea en modo correcto en muchos casos. Objetivos: Este trabajo tiene como objetivo individuar las principales habilidades (skills) para lograr una comunicación terapéutica eficaz y cómo emplearlas en la construcción y mantenimiento de la relación terapéutica con el paciente y su familia. Método: búsqueda bibliográfica con las siguientes palabras clave: comunicación, paliativos, enfermería. Se han incluido en la revisión 27 artículos de 17 revistas distintas. Resultados: Las habilidades y factores encontrados en la literatura han sido clasificados en: a. barreras a la comunicación terapéutica b. condiciones y habilidades facilitadoras de la comunicaciónvi c. habilidades de relación d. habilidades para solicitar información e. estrategias y modelos de comunicación Conclusiones: La comunicación es la herramienta principal del cuidado enfermero en cuidados paliativos, difiere de la comunicación social y tiene como objetivo aumentar la calidad de vida del paciente. La habilidad en comunicación no es un don innato sino que es el resultado de un proceso de aprendizaje continuo. Entre las habilidades más citadas y efectivas hay que recordar la escucha activa (entendida como conjunto de técnicas), el tacto terapéutico, el contacto visual, la empatía y la importancia fundamental de la comunicación no verbal. El modelo de comunicación COMFORT es el único centrado en el paciente y a la vez en su familia. Palabras clave: Habilidades comunicación, paliativos, enfermería

L’altre Segon Quintet : anàlisi formal i rítmic de l’evolució de la interpretació del repertori en els concerts en directe del Segon Quintet de Miles Davis

“L’altre Segon Quintet. Anàlisi formal i rítmic de l’evolució de la interpretació del repertori en els concerts en directe del Segon Quintet de Miles Davis” és un estudi històric i analític de la música de Miles Davis i el seu famós “Segon Quintet”. A diferència de la majoria de publicacions sobre aquesta banda, es centra únicament en els concerts en directe i el repertori que hi tocaven. Per treure a la llum la “màgia” que hi havia, he fet unes transcripcions amb un mètode propi de diverses versions de les mateixes peces al llarg dels anys i he anotat tots els fets rellevants en aspectes d’arranjaments, plantejaments estètics i interacció entre solistes i secció rítmica. Finalment he comprovat que aquesta “màgia” és fruit d’unes fórmules pautades i no és tan espontània com sembla en una primera escolta. Per altra banda, tots els músics de la banda contribueixen al so del grup, demostrant així la seva condició d’indispensables per la banda.
