Electrical stimulation of area 5 in monkeys produces a pattern of motor responses of the contralateral extremities, trunk, and head, which mirrors the topography of area 4. Stimulation of area 7 yields a pattern of eye movements similar to that obtained from the posterior parietal (area 19) and occipital (area 18) eye fields. Areas 5 and 7 may be considered as "second" or additional motor areas. They have a higher threshold of excitability than the motor cortex, and the resulting movements tend to be less precise, less fine and discrete, and are often combined movements which resemble patterns and maneuvers such as running, turning, and avoiding movements. These movements may be produced in the absence of the contralateral area 5 and the ipsilateral and contralateral precentral and postcentral gyri. Excision of areas 5 and 7 results in slight transient hypotonia and weakness of the contralateral extremities.
