    Abstract:
    Units activity of anterolateral area of rabbits motor cortex, realizing instrumental food-acquisition behaviour was studied at acute injection of ethanol and in control experiments (injection of physiological solution) in order to compare possible ethanol effects on the motor area of the cortex with effects revealed by us earlier at studying the activity of the limbic cortex units in the same experimental conditions. It was shown that after ethanol injection the number of active units and the pattern of the motor cortex units specialization in contrast to the limbic one remained constant. Nevertheless, composition of the motor cortex units involved in subserving the behaviour changed because of recruitment [correction of recrutation] of one cells (from V-VI layers of the cortex) in this process and exclusion of other ones (from II-IV layers). The value of activation frequency ratio to the frequency of the background of the involved units increased.
