Logic operations in the central nervous system-implications for information transfer mechanisms

Abstract

Extracellular unit recordings were derived from the cat sensorimotor cortex by means of tungsten microelectrodes. Evidence was obtained for the value of time-locking of impulses: a critical time interval was demonstrated as essential for modifications caused in putaminally-evoked cortical local field potentials by preconditioning stimuli delivered to the nucleus entopeduncularis. A correlation analysis was carried out on responses of neurones of the sensorimotor cortex to stimulation of the pyramid or of sensory area S1. Differentiation was made between common input and sequential firing operational conditions. Logics of and-gate and of conditional or-gate were recognized. Micro-circuitry was offered in each case. Evidence was offered for the importance of collaterals in such actions.
