Abstract

How do we rapidly and effortlessly compute a vivid veridical
> representation of the external world from the noisy and ambiguous
> input supplied by our sensors? One possibility is that the brain does
> not process all incoming sensory information anew, but actively
> generates a model of the world from past experience, and uses current
> sensory data to update that model. This classic idea has been well
> formulised within the modern framework of Generative Bayesian
> Inference. However, despite these recent theoretical and empirical
> advances, there is no definitive proof that generative mechanisms
> prevail in perception, and fundamental questions remain.
> The ambitious aim of GenPercept is to establish the importance of
> generative processes in perception, characterise quantitatively their
> functional role, and describe their underlying neural mechanisms. With
> innovative psychophysical and pupillometry techniques, it will show
> how past perceptual experience is exploited to manage and mould
> sensory analysis of the present.

Goals

The aim of GenPercept is to uncover mechanisms of generative vision
> both at local circuitry level as well at a system level Understanding
> how we perceive and interact with the world, and how past perceptual
> experience influences what we perceive.
> The project is also of clinical relevance, as these systems are prone
> to dysfunction in several neuro-behavioural conditions, including
> autism spectrum disorder
