Research Project

A model of peri-saccadic space representation in parietal cortex.

When we move our eyes the image of the world on the retina shifts rapidly. Yet, we do not perceive any such shifts, rather the world appears stable to us despite our eye movements. In this research project we build a dynamical neural model of the lateral intraparietal area (LIP) which is known to integrate stimulus position information with various kinds of eye position information. Using this model we can show how the brain uses these different kinds of information to form a stable percept of the world. We explain several distinct kinds of behavioural phenomena known from the literature about situations where this stable percept fails, as well as electrophysiological data about the temporal and spatial characteristica of the responsiveness of visual neurons in LIP.
