摘要

Cats were instrumentally conditioned to generate grouped fast (20- to 50-Hz) oscillations in motor cortex (area 4). Over seven experimental sessions, there was a spatially selective increased generation of grouped fast oscillations in that electroencephalogram lead. This locally increased generation of fast oscillations in cortex was associated with a widespread increase in synchrony of fast oscillations in thalamocortical networks, as demonstrated by crosscorrelations between intracortical, corticothalamic, and intrathalamic field potentials, A three-session extinction period abolished the local increase in generation of grouped fast oscillations and reset the thalamocortical synchrony of fast oscillations to control values, A subsequent series of seven sessions with instrumental conditioning of fast oscillations in visual cortex (area 17) reproduced the results from area 4, with a spatially selective increased generation of grouped fast oscillations in the criterion lead, associated with a widespread increase in thalamocortical synchrony of fast oscillations, In addition to their presence during the conditioning sessions, the changes in synchrony of fast oscillations were expressed during periods of quiet waking, rapid-eye-movement sleep, and nonrapid-eye-movement sleep recorded during the first hour after the end of the conditioning.
