Role of polymodal synaptic influences in temporal connection formation in neuronal microsystems of the association cortex

Neurophysiology Aims and scope

Abstract

The role of convergence of sensory influences on unit activity in the association cortex during formation of temporal connection was investigated in experiments on unanesthetized cats. A bioelectrical model of temporal connection was produced after studying unit responses to direct electrical and peripheral stimulation (photic, acoustic, electrodermal, tactile, and proprioceptive). The results showed that 42% of neurons in the association cortex and about 90% of "trained" cells are polysensory. The role of convergence of sensory influences in the formation of microsystems of trained neurons of the association cortex and the microsystemic principle of organization of conditioning mechanisms are examined.
