Adult & Developing Visual System Group
Work in my lab focuses on; (i) the functional organisation of mammalian
striate and extra-striate cortices, especially the interaction between
different information channels and 2)the role of the so-called "feedback"
projections from the "higher-order" extra-striate visual areas to the "lower-order"
visual areas (including the primary visual cortices) and subcortical visual
nuclei. We approach these problems using physiological techniques, in particular
study the receptive field properties of single neurones in a given area;selective
inactivation of so-called Y-information channel; selective reversible inactivation
of different cortical areas; cross-correlation analysis of discharges of
individual cells located in a given area or in the neighbouring areas.
The third problem on which we currently focus on is the extent, time-course
and the mechanism(s)of topographic reorganisation in mammalian visual cortices
following circumscribed lesions of retina in adult or adolescent mammals.
