Description:
When the visual cortex of a newborn kitten is removed, most neurons in the dorsal lateral geniculate nucleus degenerate, but a small population of large cells is spared. Electrophysiological recording revealed that detailed visual topography in the nucleus is abnormal and that single cells have unusually large receptive fields. These results suggest that optic axons deprived of their normal synaptic targets rearrange their connections to converge on local surviving neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murphy, E H -- Kalil, R -- New York, N.Y. -- Science. 1979 Nov 9;206(4419):713-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/493978" target="_blank"〉PubMed〈/a〉
