Présentation
Let’s admit it : brains are not computers. Indeed, computers are still deceptive compared to perceptual systems. Think for instance about architectures capable of feeding noisy, ambiguous and rapidly varying raw data to your computer. Or think about architecture performing this in an autonomous manner...
To narrow the gap between neuroscience and the theory of sensory processing computations, I am interested in bridging the statistical geometrical regularities of natural scenes with the properties of neural computations as they are observed in low-level sensory processes or through low-level behavior. For instance, has the predictability of the motion of objects in physical space an impact in the activity of neurons that detect and subsequently on eye movements ? What mechanisms are used to learn statistical regularities ? What happens if these adaptive mechanisms are dysfunctional ?
