REDISCUTINDO A NATUREZA DA PERCEPÇÃO

Eadweard Muybridge

Um ponto de partida fundamental para compreender os trânsitos entre corpo e ambiente é o estudo da percepção: o princípio de toda e qualquer experiência.

Ao contrário do que parecia consensual há alguns anos, a percepção não é apenas uma interpretação de mensagens sensoriais, mas uma simulação interna da ação, assim como, uma antecipação das conseqüências da ação.

Segundo Alain Berthoz, uma das primeiras tentativas para testar esta hipótese foi realizada em 1852 por Hermann Lotze que propunha a organização espacial das sensações visuais como resultante da sua integração com o sentido muscular. William James também descreveu, em 1890, um circuito neuronal que antecipava as consequências sensoriais do movimento. Assim, para os atos perceptivos haveria um ponto de partida determinado por um objeto complexo (a presa por exemplo) mas a representação organizada internamente pelo organismo não se restringiria a esta relação circunstancial. Isso significa que o ato perceptivo poderia prever também o que ainda não havia ocorrido. Assim, depois da simulação inicial haveria uma espécie de adaptação a estimulações futuras passíveis de serem caracterizadas por conduções perceptivas. Era preciso, portanto, suprimir a dissociação entre percepção e ação. Com base nestes estudos, Berthoz propôs o entendimento da percepção como uma ação simulada e o movimento como o nosso sexto sentido. É disso que se trata, provavelmente, a improvisação em dança: de uma aliança entre percepção e ação que aciona um fenômeno perceptivo-imaginativo e que já na ação presente prevê a ação futura.

O CÃO SOB A PELE OU O CORPO PERDIDO DO CIENTISTA

http://vimeo.com/46743310

This session will be about a story of Oliver Sacks where he describes the case of 22 years old Stephen D. who used a mix of cocaine, PCP, amphetamines.
After a vivid dream – he dreamt he was a dog in a world unimaginably rich and significant in smells – he woke up with an enhanced color vision and heightened sense of smell. In this state he could distinguish the olfactory physiognomy of all his friends and coleagues and even recognise every street and every shop by there smell. Obviously the Weltanschauung (Worldview) of Stephen D. changed dramatically during this event and the framework for generating, sustaining, and applying knowledge was altered drastically.

We use this case study as a entry point to discuss the role of the scientists body in the everyday routines in life science. Our special interest is focused on the exclusion of any type of corporality* and non explicit knowledge in the scientific language and publications.

*corporality the quality or state of being or having a body or a material or physical existence.

Paulo Pereira

Paulo de Carvalho Pereira, graduated in Biochemistry in 1990 from the University of Coimbra and received his PhD in Cell Biology in 1996. Paulo Pereira worked at Division of Clinical Toxicology, University College of London, during his PhD training and as a Post-Doc. Paulo subsequently worked as an Assistant Professor/ Visiting Scientist at Human Nutrition Research Centre on Ageing at Tufts University, Boston. Paulo Pereira is currently Director of Centre of Ophthalmology – Faculty of Medicine University of Coimbra and head of the Laboratory for Research in Biology of Ageing atIBILI, Faculty of Medicine – University of Coimbra. Paulo is also the Director of the Laboratory for Electron Microscopy at Faculty of Medicine – University of Coimbra, which is part of the National Network of Electron Microscopy. His main scientific Interests are on mechanisms of age-related cell damage and cell response to stress. He is particularly interested in the molecular mechanisms of age and diabetes-related retinal damage and on the role of ubiquitin-dependent proteolysis in such processes.

Paulo Pereira also participates and coordinates Master and PhD programmes in the area of Vision Sciences and Biomedical Reserach and he currently supervises 7 PhD students. Paulo is also interested and actively participates in projects to increase public awareness of sciences, including Bio-aesthetics and Sci-art projects. Over the last five years Paulo was the Principal Investigator on 6 externally funded (FCT) Research Grants and was author of 14 papers published in international peer-reviewed journals. In 2006 Paulo Pereira was granted A Fulbright Scholars and Researchers Program Award.

Realidade Aumentada

Ao primeiro segundo o olho da câmara revela o espaço da sala e dos objetos da sala. No segundo seguinte o olho da câmara revela-se como extensão da câmara do olho. O ato de ver e o registo do ato de ver encenam a coincidência entre olhos, óculos e câmara.
