title: [Responses of neurons of the motor and frontal cortex of monkeys during performance of purposeful activity].
abstract: Neurones of the frontal cortex in alert monkey reveal most diverse rearrangements of spike activity at the programming stage of a behavioural task. Their responses depend on 1) position of the conditioned signal, 2) direction of the forthcoming movement toward reinforcement (feeding trough), and 3) efficiency of performing the goal-directed movement, which, if correct, is reinforced with food. Units in the motor cortex have higher background activity, they are most active during triggering stage and their activity does not reflect signal position and estimation of success (by reinforcement). The suggestion is made on the role of the frontal cortex in programming of movements and estimation of their efficiency, as well as on the role of the motor cortex in their coordinated achievement involving somatic processing of the connection.
