[Functional organization of neurons in different microportions of the visual cortex in the cat].
Evoked spike activity of neighbouring neurones in microareas of the cortical visual field 18 was studied in non-anaesthetized non-immobilized cats. In most of the micropools (MP) either all neighbouring cells reacted to the presented stimulus or they all did not react. A tendency has been detected to grouping of neurones with similar convergent properties. In a considerable part of MPs in which activity of the neighbouring cells was synchronized by the action of "common input", the responses of all the studied cells in the MP were similar. In the MPs with inhibitory interactions, some neurones produced inhibitory, and other--excitatory responses. The existence of several types of functionally differing MPs is suggested.
