Document Summary
Neural activity in monkey sma (shima & tanji) Monkeys were taught six sequences of three motor responses (e. g. push-pull-turn or turn-push- pull, etc) The activity of these neurons encoded certain elements of the sequence the sma was then temporarily inactivated with muscimol (a gaba agonist which inhibits neural activity) After inactivation, monkeys could still reach for an object or make a response, but they could perform the sequence of three responses that they had previously learned firing pattern of single neuron in sma. This neuron fires only when a push response follows a pull response. Studies of sma activity in humans in humans, learned sequences of button presses activate the sma (hikosaka) If we stimulate these regions, it provokes an urge to make a movement or you anticipate that a movement is about to occur. The premotor cortex the premotor cortex is involved in learning and executing complex movements that are guided by sensory information.
