The myogenic automatism of the systemic heart of Octopus vulgaris (Cephalopoda: Coleoidea): evidence for localized stretch sensitivity and pacing activity

The localization of the stretch sensitivity and myogenic automatism in the systemic heart of Octopus vulgaris has been studied on an isolated preparation in which the ventricle was zoned by ligatures. Each region has been submitted to two different levels of internal hydrostatic pressure (1 and 2 kPa). Only the two atrio-ventricular regions were able to contract regularly when submitted to internal pressure, with a frequency dependent from the pressure value, while the ventricle-aortic region was insensitive to the stretching by internal pressure. This result supports the hypothesis that the automatism in this heart is localized. Electrocardiogram recordings from different areas of an isolated and perfused preparation of the systemic heart ventricle are also reported, which suggest that the electrical activity of the ventricle originates in two narrow areas near the atrio-ventricular valves.

The debate on human automatism in mid-Victorian England

During the 1830s, Marshall Hall carried out innumerable experiments on a great variety of animals to establish the concept of a ‘reflex arc’. In France F.L.Goltz showed that decerebrate frogs were still capable of complex behaviours. Thomas Laycock in England and Ivan Sechenov in Russia sought to apply the reflex idea to the brain. This paper follows the debate in the periodical literature of mid-Victorian England and discusses the contributions of WB Carpenter, Herbert Spencer, TH Huxley, W Clifford and others. The previous outing of this issue in the post-Cartesian seventeenth century had been largely suppressed by ecclesiastical authority. In the nineteenth century ecclesiastical power had waned, at least in England, and the debate could take a more open form. As neurophysiology and behavioural science developed, with the widespread acceptance of Darwinian evolution, it became more and more difficult to deny that brain and mind were part of the natural world and subject to the usual laws of cause and effect. This, of course, had powerful implications for the human self-image and for jurisprudence. These implications are still with us and the work of neurophysiologists such as Benjamin Libet have only reinforced them. Should humans be regarded as ‘automata’ and, if so, what becomes of ‘free will’, ‘responsibility’, and the rule of law? The Victorian debate is still useful and relevant.

Observar el movimiento : construcción del formato de campo “el salto en psicomotricidad durante el tercer año de vida”

[Es]Este artículo repasa los hitos más significativos de la elaboración del instrumento de observación del formato de campo “el salto en psicomotricidad durante el tercer año de vida”. La aplicación de la Metodología Observacional a la Práctica Psicomotriz Aucouturier (PPA)es posible ya que existe una doble complementariedad entre ambas: la metodología observacional es la única que puede evaluar y explicar, y no sólo describir, el complejo flujo de actividad psicomotriz infantil o expresividad psicomotriz y la práctica psicomotriz aucouturier, a su vez, cumple el perfil óptimo de la metodología observacional. El proceso metodológico observacional impone entre sus condiciones la sistematización del instrumento de observación; lo que comienza siendo un sistema de categorías en base a la propuesta observacional de la propia PPA, termina siendo un formato de campo al servicio del objetivo inicial de la investigación, que es la evaluación del comportamiento psicomotor infantil.

El salto a los tres años en psicomotricidad : observación del comportamiento psicomotor infantil

[ES] El objetivo de esta investigación es evaluar la actividad de saltar de un grupo escolar natural de 15 criaturas entre los dos y los cuatro años en el contexto de la Práctica Psicomotriz Aucouturier. La perspectiva teórica adoptada ha sido la teoría psicogenética y dialéctica de Henri Wallon. Según ésta, saltar es un automatismo natural regulado por el aparato funcional del equilibrio que se aprende en la primera infancia. La metodología utilizada ha sido la observacional. El diseño es nomotético, de seguimiento y multidimensional, y el instrumento de observación es el formato de campo "el salto en psicomotricidad durante el tercer año de vida". Los resultados, obtenidos mediante la aplicación prospectiva del análisis secuencial de retardos, informan sobre la adquisición del automatismo o proceso de aprendizaje, sobre el contenido del mismo o manejo del vértigo y sobre su resultante conjunta o tipos básicos de salto en psicomotricidad, sus características y su evolución.

A gramática da quietude: um estudo sobre hábito e confiança na formação da identidade

Esse trabalho tem por objetivo investigar o papel do hábito e da confiança na formação da identidade. Ainda que inspirada em estudos que revelam a centralidade da confiança para a constituição das sociedades e examinam sua condição no contexto sócio-cultural contemporâneo, a discussão focaliza essencialmente o domínio do desenvolvimento infantil. Constatando o destaque conferido à confiança pela escola psicanalítica das relações de objeto, a análise do conceito incide prioritariamente na obra de D. W. Winnicott. Partindo do pressuposto que a confiança ocupa um lugar central na metapsicologia do autor, que contrasta com a limitada conceituação teórica que cerca seus diferentes significados e funções, propõe-se estudá-la em dois tempos: os da gênese e da reprodução da confiança. O estudo do conceito de hábito constitui uma etapa prévia e associada ao exame da confiança. Permitindo relevar os aportes corporais e a importância das interações regulares e previsíveis com o ambiente para a gênese da confiança, o hábito é investigado a partir de autores da filosofia e da sociologia. Ressaltam-se os pressupostos comuns e os elementos de convergência entre diferentes teorias do hábito cujas descrições enfatizam sua base corpórea e contornam discussões tradicionais que reduzem sua definição às idéias de repetição e automatismo. Associando-se ao estabelecimento de um contexto seguro pela antecipação das conseqüências da ação, o hábito contribui para a adaptação flexível ao meio e se apresenta como o fundamento inicial da construção da confiança. Em seguida, a investigação se orienta para os mecanismos de reprodução e do exercício da confiança. Submetida às novas configurações funcionais do ambiente que acompanham o desenvolvimento da criança . a redução da segurança, o aumento da autonomia e a liberdade para correr riscos ., a reprodução da confiança reflete a incidência das ações agressivo-criativas no espaço transicional. Além da referência a psicanalistas que partilham os pressupostos centrais da teoria de Winnicott, a análise da confiança é enriquecida a partir das contribuições da psicologia do desenvolvimento atual. O trabalho explora ainda três conquistas no desenvolvimento descritas por Winnicott como relacionadas à confiança: estar só, não-integrar-se e a capacidade de doar.

Cinema e pensamento em Gilles Deleuze: a distinção dos automatismos pela passagem da imagem-movimento para a imagem-tempo

Esta dissertação investiga o conceito de imagem-movimento e de imagem-tempo do filósofo Gilles Deleuze por meio das implicações contidas na passagem de um conceito para o outro. O aparecimento de regimes de imagem constituem mundos e automatismos específicos: o automovimento do chamado regime orgânico e a autotemporalização presente no regime inorgânico. A substituição da imagem-movimento pela imagem-tempo caracteriza-se por uma reversão da subordinação do tempo pelo movimento. Dessa forma, apresenta a conquista da realidade íntima do tempo puro, em que o tempo aparece completamente emancipado de determinações cronológicas. Ao marcar essa passagem, deve ser entendido como Deleuze alcança um novo regime de imagem e pensamento a partir de uma aliança com a arte cinematográfica. A transposição entre esses dois regimes expressa a mudança de um regime que afirma um autômato motor para outro em que há o surgimento de um autômato capaz de levantar o fundamental do pensamento. E mais decisivamente erigir o plano de imanência.

Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.

Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different contexts ("butcher-on-the-bus" phenomenon). The present fMRI study investigated the automatic binding of faces and scenes. In the face-face (F-F) condition, faces were presented alone during both encoding and retrieval, whereas in the face/scene-face (FS-F) condition, they were presented overlaid on scenes during encoding but alone during retrieval (context change). Although participants were instructed to focus only on the faces during both encoding and retrieval, recognition performance was worse in the FS-F than in the F-F condition ("context shift decrement" [CSD]), confirming automatic face-scene binding during encoding. This binding was mediated by the hippocampus as indicated by greater subsequent memory effects (remembered > forgotten) in this region for the FS-F than the F-F condition. Scene memory was mediated by right parahippocampal cortex, which was reactivated during successful retrieval when the faces were associated with a scene during encoding (FS-F condition). Analyses using the CSD as a regressor yielded a clear hemispheric asymmetry in medial temporal lobe activity during encoding: Left hippocampal and parahippocampal activity was associated with a smaller CSD, indicating more flexible memory representations immune to context changes, whereas right hippocampal/rhinal activity was associated with a larger CSD, indicating less flexible representations sensitive to context change. Taken together, the results clarify the neural mechanisms of context effects on face recognition.

L'habitude en matière de conduite automobile : une analyse de ses composantes et du rôle qu'elle joue dans le maintien et la régulation des comportements de conduite

« La grande majorité des accidents demeure liée aux comportements dangereux des usagers de la route ». Cet énoncé, lapidaire, fait aujourd’hui figure d’évidence au sein de la communauté des intervenants en sécurité routière. Il repose pourtant sur des prémisses discutables. Le problème le plus fondamental réside dans le fait que la recherche des dernières décennies s’est presque toute entière vouée à l’analyse des seuls aspects défaillants de la conduite (l’accident, les infractions, les erreurs et les fautes de conduite, les conducteurs à risque ou dysfonctionnels, les attitudes et traits de caractère incitant à la conduite dangereuse, etc.). Ce faisant, on a fini par oublier qu’il nous restait encore beaucoup de choses à apprendre sur le fonctionnement usuel de la conduite automobile. Comment, en effet, peut-on escompter élucider tous les rouages de la dynamique accidentelle sans avoir au préalable cerné, et bien compris, les mécanismes de la conduite « ordinaire » ? Comment peut-on parvenir à approfondir notre compréhension des comportements de conduite si l’on fait totalement abstraction de toutes les activités courantes, « normales », auxquelles se livrent les conducteurs lorsqu’ils sont au volant de leur véhicule ? C’est dans la perspective de mieux comprendre les comportements de conduite, dans leur complexité et dans leur diversité, que la présente thèse a été réalisée. Y a plus spécifiquement été examinée la question des habitudes en raison de leur prédominance dans l’activité de la conduite, mais également en raison de leur résistance, des obstacles bien concrets qu’elles sont susceptibles d’opposer à tous ceux qui tentent de modifier les comportements individuels de conduite. Des entrevues en profondeur, menées auprès de trente conducteurs et conductrices âgé(e)s de 17 à 54 ans, devaient permettre de répondre, entre autres, aux questions suivantes : De quoi sont constituées les différentes habitudes en matière de conduite automobile ? Quelle place occupent-elles dans la conduite des individus ? En quoi constituent-elles un frein au changement, à la modification des pratiques adoptées ? Quelles sont les dimensions qui participent à leur installation ? Les résultats de l’analyse ont permis de jeter les bases d’un modèle des comportements de conduite où les sensations corporelles se voient conférer un rôle des plus centraux, et où l’habitude – bien davantage caractérisée par la notion de confort que par celles d’automatisme ou de répétition – concourt non seulement à la pérennité, mais également à la régulation des conduites adoptées sur la route.

Le jeu littéraire : appropriation et transformation discursive et textuelle dans Certainement Pas de Chloé Delaume ; suivi de Jouer le je

Dans Certainement Pas, je m’intéresserai à la problématique du jeu littéraire dans son rapport à la contrainte. Comment Chloé Delaume réussit-elle dans un premier temps à s’approprier un certain nombre de discours culturels et de formes a priori extralittéraires pour ensuite les transformer? Dans un second temps, comment s’y prend-elle pour « phagocyter » dans son écriture une pléthore de références littéraires? Conséquemment, quelle conception de la littérature livre-t-elle? Veut-elle, par l’aspect ludique de son roman, rendre un hommage filial aux auteurs d’hier et ainsi adopter une position empreinte de dévotion? Essaye-t-elle, au contraire, de « déchiqueter-dégurgiter » ces textes paternels et agir en iconoclaste? En procédant de cette façon, détruit-elle ou non le mythe de l’originalité en littérature? Finalement, comment s’effectue la réception de son texte ? Jouer le je est un projet d’écriture prolongeant les réflexions sur la place du jeu et de la contrainte dans la littérature. Prenant la forme d’une pièce de théâtre, il cherche à travailler la problématique de l’automatisme langagier actuel et devient une tentative de destruction de celui-ci. Ce texte met en scène deux personnages. La protagoniste principale, une jeune femme de vingt-cinq ans nommée Plume Liddell, étudiante en immunologie souffrant de dyslexie linguistique, participera à six séances de psychothérapie au cours desquelles elle parlera d’elle-même. L’autre personnage: la psychologue, restera muette ou presque tout au long des séances.

O outro diálogo: uma compreensão do diálogo interno

This thesis aims to enable a wider comprehension on thought operation as well as suggest alternatives for the formation of reflexive, critical, autonomous and creative individuals. The research defends the idea that it is possible for an individual to develop vigilant attention that makes thought flexibilization and change in the course of action, possible. This operation is called Internal Dialogue and is essentially characterized by a continuous openness towards novelty and learning. This makes it possible to minimize the usual way thought operates, in a automatic fashion (automatism). The research was based on theoretical references and ideas of David Bohm (1989;1994;2005) and Michael Polanyi (1983). The main emphasis was the understanding that a crisis situation enables awareness and state of alert that favors a more flexible thought pattern (Aragão Gomes, 1994, 1997). The methodology used was presentation and analysis of these moments through autobibliographical records with indication of crisis on behalf of the subjects. Other criteria were also used that enabled the composition of the analyzed material such as the fact that: the subjects were public and real, the data was available through accessible material; the subjects identified themselves as in crisis; these crisis were of varied kinds; they had different social, cultural and professional profiles. Thus, three auto-bibliographical elements were selected: the Infidel: the story of a woman that challenged Islam (2007), written by the political Muslim author Ayaan Hirsi; Still me: memories (2001), of the actor Christopher Reeve as well as Confessions of a Philosopher (2001), by the philosopher Bryan Magee. In these books an analysis was made related to parts that stated action an though operation that express internal dialogue. These were organized into categories that were pointed out as relevant for the identification of internal dialogue such as: Perceptions of physical reaction; emotions, beliefs and issues, individual actions, self judgment and thought, self questioning, comprehension, observation and empirical investigation, perception of the changes they performed in the world, escape of conditioning as well as action that resulted in new meaning. The analysis performed reinforces our goal once it sated that internal dialogue is an important tool that allows thought awareness, minimizing common automatism and making consciousness possible as well as favoring the occurrence of critical and reflexive thought. Thus, final considerations deal with the need for the development of teaching methodologies that address internal dialogue as a counterpoint to the many daily action that reinforce the automatism of thought

Neurocisticercose e síndrome de lennox-gastaut: relato de caso

Relata-se o caso de uma menina que, aos 2 anos de idade, apresentou a forma epiléptica, hidrocefálica e encefalítica da neurocisticercose, diagnosticada por exame do líquido cefalorraqueano e tomografia computadorizada de crânio, evolução com crises polimórficas, episódios de descompensação da hipertensão intracraniana por obstrução do sistema de derivação ventriculoperitoneal, retardo no desenvolvimento neuropsicomotor e cegueira até que, aos 10 anos de idade, foi diagnosticada síndrome de Lennox-Gastaut. Atualmente, a paciente tem 16 anos, apresenta sequelas neurológicas e crises parciais complexas com automatismos, parcialmente controladas com o uso de clobazan e oxcarbazepina. A primeira associação de neurocisticercose e síndrome de Lennox-Gastaut foi descrita em 1973, por Frochtengarten & Scarante, em uma menina com quadro clínico semelhante ao do caso relatado.
