pubmed-article:3584542 | pubmed:abstractText | Receptive fields defined for small clusters of neurons within the middle cortical layers of area 3b differed little in size or in the skin locations represented among: alert, nitrous oxide-anesthetized, deep sodium pentobarbital-anesthetized, and ketamine-anesthetized owl monkeys. Repeated recordings from nearly identical cortical loci yielded nearly identical multi-unit receptive fields under different conditions of anesthesia. | lld:pubmed |
