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
TLDR
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.
TLDR
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
TLDR
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
TLDR
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
TLDR
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.
Anatomo‐functional organization of the ventral primary motor and premotor cortex in the macaque monkey
TLDR
The posterior areas F4 and F1 appear to be involved in organizing and controlling goal‐directed mouth motor acts and simple movements within different parts of the external (dorsal sector) and internal (ventral sector) space, whereas area F5 code motor acts at a more abstract level, thus enabling the emergence of higher order socio‐cognitive functions.
Simultaneous recording of macaque premotor and primary motor cortex neuronal populations reveals different functional contributions to visuomotor grasp.
TLDR
These properties are consistent with the notion that F5 grasping-related neurons play a role in translating visual information about the physical properties of an object into the motor commands that are appropriate for grasping, and which are elaborated within M1 for delivery to the appropriate spinal machinery controlling hand and digit muscles.
Space-Dependent Representation of Objects and Other's Action in Monkey Ventral Premotor Grasping Neurons
TLDR
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
TLDR
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.
Hierarchical Organization Within the Ventral Premotor Cortex of the Macaque Monkey
TLDR
The PMv subregions form a hierarchically organized integral system from decision-making to eye-hand coordination under various behavioral circumstances, and are hierarchically higher than the F4d, F5p, and F5v complexes.

TLDR
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
TLDR
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.

TLDR
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.
TLDR
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
TLDR
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
TLDR
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.
Afferent properties of periarcuate neurons in macaque monkeys. II. Visual responses
TLDR
It is argued that neurons with a receptive field consisting of several responding areas, some in one sensory modality and some in another, have a praxic function and that they are involved in organizing sequences of movements.

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