Motor control function of the prefrontal cortex.

The anatomical and functional evidence supports the thesis that prefrontal cortex has access to and can direct the output of several motor centres.

Connectivity of the Primate Sensory-Motor Cortex

On account of the functional baseline alluded to above having its origins in human behavior, this chapter will be devoted entirely to the examination of connectivity in the monkey brain.

Corticostriatal Projections from the Cingulate Motor Areas in the Macaque Monkey

A series of recent studies have been performed to analyze the corticostriatal projections from the MI, SMA, pre-SMA, PMd, and PMv, with special reference to the organization of input zones from their forelimb representations.

Motor and visual-motor functions of the premotor cortex

It is concluded that in area 6 there is a vocabulary of motor acts, coded at a single neuron leveL, that are located in various frontal and parietal association areas and that the use of motors stored in these areas is at the basis of cortical motor organization.

Converging evidence from microstimulation, architecture, and connections for multiple motor areas in the frontal and cingulate cortex of prosimian primates

The results indicate that prosimian galagos have a complex of motor areas that closely resembles that in monkeys and suggest that at least 10 motor fields emerged early in primate evolution.



The Supplementary Motor Area — Control System for Posture?

The supplementary motor area (SMA) is interconnected with the precentral motor cortex and receives its main afferents from the somatosensory areas I, II and 5; it is therefore most likely concerned

Posterior parietal association cortex of the monkey: command functions for operations within extrapersonal space.

A large proportion of area 5 neurons were relatively insensitive to passive joint rotations, as compared with similar neurons of the postcentral gyrus, but were driven to high rates of discharge when the same joint was rotated during an active movement of the animal.

Supplementary motor area in the monkey: activity of neurons during performance of a learned motor task.

The findings suggest that the discharges of a large number of neurons in SMA are changing during particular movements of either arm, and that only a small number of cells receive peripheral afferent sensory input.

The distribution of labeled neurons following single injections of HRP into different regions of the motor cortex arm area indicated that the VL arm area is topographically organized, particularly its caudal part.

Intracortical connectivity of architectonic fields in the somatic sensory, motor and parietal cortex of monkeys

Anterograde and retrograde transport methods were used to study the corticocortical connectivity of areas 3a, 3b, 1, 2, 5, 4 and 6 of the monkey cerebral cortex, finding possible multiple representations of the body surface in the component fields of the first somatic sensory area (SI).

Premotor cortical ablations in monkeys: contralateral changes in visually guided reaching behavior.

In rhesus monkeys (Macaca mulatta), ablation of the premotor and supplementary motor areas and the adjoining rostral half of the precentral gyrus impairs the capacity of the contralateral arm to
