Description:
The cerebral cortex receives sensory input from the periphery by means of thalamic relay nuclei, but the flow of information goes both ways. Each cortical area sends a reciprocal projection back to the thalamus. In the visual system, the synaptic relations that govern the influence of thalamic afferents on orientation selectivity in the cortex have been studied extensively. It now appears that the connectivity of the corticofugal feedback pathway is also fundamentally linked to the orientation preference of the cortical cells involved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murphy, P C -- Duckett, S G -- Sillito, A M -- New York, N.Y. -- Science. 1999 Nov 19;286(5444):1552-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, St. George's Hospital Medical School, Tooting, London SW17 0RE, UK. p.murphy@sghms.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10567260" target="_blank"〉PubMed〈/a〉
