[Participation of the pallidum in formation of different forms of adaptive behavior].
Participation of associative (O2, OP), motor (Prc1) and somatosensory (Pc3) neocortical fields, as well as of the pallidum, in intercentral integrative processes of various kinds of adaptive activity, differing in manifestation of the motor component,-- was studied on dogs with chronically implanted electrodes by parameters of evoked potentials (EP). Establishment of indifference of the non-reinforced stimulus is not connected with elaboration of motor programs. O2 and OP cortical fields are more significant elements, while the pallidum is a less significant element, of the corresponding integration. At the beginning of the elaboration of avoidance reaction, the indifferent meaning of the same stimulus changes to the signal one. The participation of the pallidum in the activated structures is probably connected with an involvement of afferentation from the stimulated limb. During the elaboration of the motor reaction a functional connection is manifested between the pallidum and the motor and somatosensory cortices in the aspect of their involvement in the formation of an adaptive motor program.
