The interactions of central neurons in conditioning and the influence of some limbic structures upon them

Abstract

The interactions between the neurons in the cortex and the subcortical visual structures were studied with multimicroelectrode technique. Neurons revealing conditioned reactions were found at various levels of the brain. It is assumed that they are involved, by the conditioning, in a special cellular network: the microsystem, which is considered to be the definite functional level of brain processing mechanisms. The influence of some limbic structures on the formation of the microsystems of conditioning neurons was found. It was concluded that the elaboration or extinction of the temporary connection is performed through formation or destruction of a microsystem which takes part in the conditioning.
