Keywords : computational neuroscience, population coding, decoding, information theory, Bayesian models, early vision.

The aim of my work is to understand the relationship between the activity of single neurons and populations of neurons in sensory cortex with the perceptual world we experience.
More specifically, using large-scale simulations and theoretical methods, I am trying to understand how information is encoded and transmitted in the activity of single neurons and populations of neurons, and how it can be optimally decoded and related to behavioral performance/ conscious perception.
