Le Centre de Neurosciences Système et Cognition (NeuroCs), et l'Institute of NeuroScience (IoNS) et l'Institut de Psychologie (IPSY) ont le plaisir de vous inviter au séminaire donné par Irving Biederman (University of Southern California).
Afin de vous mettre en appétit, voici un résumé de son exposé:
"The surprising discovery of a gradient of opioid receptors in cortical areas engaged in perception and cognition may provide the key for understanding the neural basis of aesthetics. These receptors are sparse in the early sensory areas and dense in association areas. If we assume that experiences are preferred that maximize this opioid activity, then preferred inputs will tend to be those that are richly interpretable (not just complex), insofar as they would produce high activation in areas that have the greatest density of opioid receptors. Once an input is experienced, however, competitive learning would serve to reduce associative activity and hence opioid release, resulting in habituation and boredom. Behavioral and neuroimaging tests have confirmed this account. This system serves to maximize the rate at which we acquire new but interpretable information. Aesthetic motivation may thus derive from the system that renders us infovores"
