Description:
The primate visual system is often divided into two channels, designated M and P, whose signals are relayed to the cerebral cortex by neurons in the magnocellular and parvicellular layers of the dorsal lateral geniculate nucleus. We have identified a third population of geniculocortical neurons in the dorsal lateral geniculate nucleus of macaques, which is immunoreactive for the alpha subunit of type II calmodulin-dependent protein kinase. This large third population occupies interlaminar regions (intercalated layers) ventral to each principal layer. Retrograde labeling of kinase-immunoreactive cells from the primary visual cortex shows that they provide the geniculocortical input to cytochrome oxidase-rich puffs in layers II and III.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hendry, S H -- Yoshioka, T -- EY 06432/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 22;264(5158):575-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zanvyl Krieger Mind/Brain Institute, Johns Hopkins University, Baltimore, MD 21218.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8160015" target="_blank"〉PubMed〈/a〉
