Neural Basis of the Functions of the Primary Visual Cortex: Roles of Feedforward and Intracortical Inputs

Abstract

Signals from the eyes undergo extensive processing at the level of the primary visual cortex so that basic features in the scene such as lines, edges, colours and movement are coded in the activity of individual neurones. This project aims to further our understanding of this process at the basic cellular level. This will not only enable interventions that would help those with poor sight but also give us an insight into basic brain circuitry and its derangement in many neurological disorders.
