Barak A. Pearlmutter: "Challenging The Optimally Hypothesis in Sensory Processing, Non-Psychotic Hallucinations, and The Visual Zwicker: Channeling Professor Brian O'Blivion"

Datum objave: 19. 12. 2011
Seminar za temelje matematike in teoretično računalništvo
Torek, 19. 12. 2011, od 12h do 14h, Plemljev seminar, Jadranska 19

Jutrišnji seminar bo imel nekoliko nenavadno, a zanimivo in relevantno temo. Ker sem dobil povzetek zadnji trenutek, prejemnike tega obvestila lepo prosim, da na seminar povabijo tudi nematematike, ki jih zanima kognitivna znanost. Hvala! 

Abstract: Our understanding of information processing in the brain is largely based on application of the optimality hypothesis which has been so successful throughout biology. The ubiquity of non-psychotic hallucinations following a diminution of sensory input, a phenomenon present in all sensory modalities, poses a challenge to the optimality theory of sensory processing. Such hallucinations are difficult to study, due to both their apparently subjective nature and to the difficulty of constructing animal models. In this talk we will survey (a) what is interesting and mysterious about the brain; (b) some hightlights, both mathematical and experimental, of the optimal sensory processing hyptothesis; and (c) challenges to this hypothesis. We will then turn our attention to the scientific history and nature one particular challenge: non-psychotic hallucinatory phenomena. We proceed to present recent results including a connection between the Zwicker tone and tinnitus, and attempt to replicate the Videodrome effect (Cronenberg, 1983).

Vabljeni!
