Description:
Intracellular recordings from simple cells of the cat visual cortex were used to test linear models for the generation of selectivity for the direction of visual motion. Direction selectivity has been thought to arise in part from nonlinear processes, as suggested by previous experiments that were based on extracellular recordings of action potentials. In intracellular recordings, however, the fluctuations in membrane potential evoked by moving stimuli were accurately predicted by the linear summation of responses to stationary stimuli. Nonlinear mechanisms were not required.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jagadeesh, B -- Wheat, H S -- Ferster, D -- R01 EY04726/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1901-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266083" target="_blank"〉PubMed〈/a〉
