SPATIOTEMPORAL ORGANIZATION OF FUNCTIONS OF CORTICAL-NEURONS DURING CONDITIONING TO TIME

Multiunit activity in the motor cortex of cats was analysed during foo d-procuring conditioning to time (2-minute interval). Comparison of be havioural and neurophysiological correlates at the initial stage of co nditioning showed that it was accompanied by very complicated system t ransformations which were different for neuronal micro- and macrostruc tures. Systemic processes in the micro- and macroareas were distinguis hed by a specificity of space distribution, quantity, strength, and st ability of manifestations of functional connections. Capability of neu rons for functional orientation, increase of percentage of incidence o f functional connections in the second half of the conditioned interva l, considerable destabilization of all neuronal associations at the la st and highest stage of conditioning were the common features for micr o- and macroareas during formation of the food-procuring conditioned r esponse.
