Description:
Complex cells in striate cortex of macaque showed a rapid pattern-specific adaptation. Adaptation made cells more sensitive to orientation change near the adapting orientation. It reduced correlations among the responses of populations of cells, thereby increasing the information transmitted by each action potential. These changes were brought about by brief exposures to stationary patterns, on the time scale of a single fixation. Thus, if successive fixations expose neurons' receptive fields to images with similar but not identical structure, adaptation will remove correlations and improve discriminability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muller, J R -- Metha, A B -- Krauskopf, J -- Lennie, P -- EY01319/EY/NEI NIH HHS/ -- EY04440/EY/NEI NIH HHS/ -- EY06638/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Aug 27;285(5432):1405-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Visual Science and Department of Brain and Cognitive Sciences, University of Rochester, Rochester, NY 14627, USA. jim@monkeybiz.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10464100" target="_blank"〉PubMed〈/a〉
