[The functional role of the motor area of the cortex in the acquisition of escape reactions in dogs].
The model of escape conditioning similar to classical (pavlovian) was proposed. During shock application to the hind limb (a conditioned stimulus) the ipsilateral foreleg flexion was elicited by a stimulation of the motor cortex (an unconditioned stimulus); both stimuli were turned off in the course of the forepaw lifting. Such uniform pairings resulted in elaboration of a reaction of the foreleg flexion in response to the shock. Prolonging the shock by 3 s after the cortical stimulation led to a rapid extinction of the acquired response. So a possibility to instrumentalize movements elicited by stimulation of the motor cortex (MI) was proved. This is in argument in favour of an assumption that the established "instrumental" connection (drive-motor structures) can be addressed directly to the motor cortex.
