[The role of polymodal synaptic influences in the formation of temporary connections in the microsystems of association cortex neurons].

Significance of various sensory convergence of the neuronal activity was investigated in unanaesthetized cats in the process of elaboration of time connections. The elaboration of time connection was realized after studying neuronal responses elicited by the direct electrical or sensory stimulation (light, sound, tactile and proprioceptive stimulation). 42 per cent of all neurons and about 90 per cent of learned cells were found to be polysensory in the investigated cortex. The data obtained are considered from the standpoint position of the hypothesis on the microsystem principle of organization underlying time connection and convergence.
