SummaryThe functional properties of neurons located in the rostral part of inferior area 6 were studied in awake, partially restrained macaque monkeys. The most interesting property of these neurons was that their firing correlated with specific goal-related motor acts rather than with single movements made by the animal. Using the motor acts as the classification criterion we subdivided the neurons into six classes, four related to distal motor acts and two related to proximal motor acts. The… 

Functional organization of inferior area 6 in the macaque monkey

By combining single neuron recording and intracortical microstimulation, it is found that inferior area 6 is somatotopically organized and argued that the receptive field arrangement and the response properties are more complex in area F4 than in the primary motor cortex.

Functional properties of grasping-related neurons in the dorsal premotor area F2 of the macaque monkey.

The main result is that almost all studied neurons were selective for both the type of prehension and the wrist orientation required for grasping an object, indicating an important role of F2 in the control of goal-related hand movements.

Parietal cortex neurons of the monkey related to the visual guidance of hand movement

The results suggest that the hand-movement-related neurons of the parietal cortex are concerned with the visual guidance of the hand movement, especially in matching the pattern of movement with the spatial characteristics of the object to be manipulated.

Response Properties of Motor Equivalence Neurons of the Primate Premotor Cortex

A three layer neural network model showed that the combination of effector invariant discharge with non-invariant discharges could help reduce the number of decoding errors when the network attempts to compute the correct movement metrics of the right effector.

Inferior parietal somatosensory neurons coding face-hand coordination in Japanese macaques

These neurons discharged more strongly when the animal executed face-hand coordinated behavior, especially eating behavior, than when somatosensory stimuli were given to RFs passively, or when face movements and hand movements were executed separately.

Space-Dependent Representation of Objects and Other's Action in Monkey Ventral Premotor Grasping Neurons

Interestingly, canonical-mirror neurons appear to code object as target for both one's own and other's action, suggesting that they could play a role in predictive representation of others' impending actions.

Understanding motor events: a neurophysiological study

It is reported here that many neurons of the rostral part of inferior premotor cortex of the monkey discharge during goal-directed hand movements such as grasping, holding, and tearing, which indicates that premotor neurons can retrieve movements not only on the basis of stimulus characteristics, but also on the based of the meaning of the observed actions.

Functional organization of inferior parietal lobule convexity in the macaque monkey: electrophysiological characterization of motor, sensory and mirror responses and their correlation with cytoarchitectonic areas

The present data suggest that the IPL plays an important role in both action organization and action understanding and should be considered part of the motor system.

Grasping-Related Functional Magnetic Resonance Imaging Brain Responses in the Macaque Monkey

Whole-brain macaque fMRI motor studies will be instrumental in establishing possible homologies concerning grasping organization in the human and monkey brains, bridging the gap between human imaging and monkey electrophysiology.

There is a separate and rather extensive mouth (or face) area in the parietal association cortex of the monkey, which is prominently related to the stimulation or motor activity of the face.

Neurons related to goal-directed motor acts in inferior area 6 of the macaque monkey

A new class of neurons was identified in the rostral part of inferior area 6 in the macaque monkey (Macaca nemestrina) which fire in relation to motor acts which have a particular aim such as reaching, grasping or holding.

Functional organization of inferior area 6 in the macaque monkey

By combining single neuron recording and intracortical microstimulation, it is found that inferior area 6 is somatotopically organized and argued that the receptive field arrangement and the response properties are more complex in area F4 than in the primary motor cortex.

Functional organization of inferior area 6.

It is proposed that inferior area 6 contains a vocabulary of motor acts related to hand-mouth movements, and the possibility is discussed that a series of vocabularies where movements of various complexity are stored represents the neural basis of cortical motor organization.

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.

I. Functional properties of neurons in lateral part of associative area 7 in awake monkeys

The lateral part of area 7, area 7b, of alert, behaving macaque monkeys was investigated using transdural microelectrode recording technique and revealed the existence of an integrative system which analyzes the direction of a stimulus moving in one sensory system using an other sensory system as a reference.

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.

Relationship between the activity of precentral neurones during active and passive movements in conscious monkeys

Of 362 task-related neurones, 176 neurones showed definite modulation of their discharge frequency which could be related to the performance of specific voluntary movements about one joint, or at a number of associated digit joints, and were classified to have discharges associated with particular voluntary movements of shoulder, elbow, wrist, hand or fingers.
