Microstimulation and anatomical techniques were combined to reveal the organization and interhemispheric connections of motor cortex in owl monkeys. Movements of body parts were elicited with low levels of electrical stimulation delivered with microelectrodes over a large region of precentral cortex. Movements were produced from three physiologically defined cortical regions. The largest region, the primary motor field, M‐I, occupied a 4‐6mm strip of cortex immediately rostral to area 3a. M‐I… 
Representations of Fine Digit Movements in Posterior and Anterior Parietal Cortex Revealed Using Long-Train Intracortical Microstimulation in Macaque Monkeys
TLDR
It is proposed that these multiple and expanded motor representations of the digits co-evolved with the emergence of the opposable thumb and alterations in grip type in some anthropoid lineages.
Architectionis, somatotopic organization, and ipsilateral cortical connections of the primary motor area (M1) of owl monkeys
TLDR
The results indicate that M1 interacts directly with at least three non‐primary motor areas and at least six somatosensory areas, and the extent and somatotopic organization of M1 was determined by making detailed microstimulation movement maps and relating the results to cortical architectonics.

TLDR
Electrical stimulation mapping with currents below the threshold of afterdischarges showed somatotopic organization of supplementary motor cortex with the lower extremities represented posteriorly, head and face most anteriorly, and the upper extremities between these two regions.
Converging evidence from microstimulation, architecture, and connections for multiple motor areas in the frontal and cingulate cortex of prosimian primates
TLDR
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 size of corpus callosum correlates with functional activation of medial motor cortical areas in bimanual and unimanual movements.
TLDR
The results suggest that corpus callosum modulates the activity of the supplementary motor and cingulate cortical areas depending on temporal complexity of bimanual movements.
Organization of the posterior parietal cortex in galagos: II. Ipsilateral cortical connections of physiologically identified zones within anterior sensorimotor region
TLDR
Differences in connections of functionally distinct movement zones of the posterior parietal cortex in galagos identified by intracortical microstimulation with long stimulus trains are consistent with functional parcellation of PPC, and they identify parts of cortical networks that mediate different motor behaviors.
9 A map of complex movements in motor cortex of primates
We used electrical microstimulation to study the organization of motor cortex in awake monkeys. Stimulation on a behaviourally relevant time scale (0.5–1 s) evoked coordinated, complex postures that
Thalamocortical connections of functional zones in posterior parietal cortex and frontal cortex motor regions in New World monkeys.
TLDR
In owl and squirrel monkeys, long-duration electrical stimulation distinguished several functional zones within the PPC and motor/premotor cortex (M1/PM).

TLDR
There is a clear rostrocaudal progression of orofacial, forelimb, and hindlimb movement representations in the SMA, observed by observing stimulation-evoked movements of 2 rhesus monkeys.
Corpus callosum connections of subdivisions of motor and premotor cortex, and frontal eye field in a prosimian primate, Otolemur garnetti
TLDR
The sparse interhemispheric connections of theForelimb sector of M1 suggests that the control of each forelimb is largely from the contralateral M1 in galagos, as in other primates.

The relation of corpus callosum connections to architectonic fields and body surface maps in sensorimotor cortex of new and old world monkeys
TLDR
Corpus callosum connections of parietal and motor cortex were studied in New World owl monkeys and Old World macaque monkeys after multiple injections of 3H‐proline and horseradish peroxidase, HRP, into one cerebral hemisphere and extensive microelectrode mapping of architectonic Areas 3b, 1, and 2 of the other hemisphere.
Organization of the face representation in macaque motor cortex
TLDR
The face representation in precentral motor cortex in macaque monkeys was stimulated with microelectrodes with the most commonly evoked muscle response in zygomaticus, which retracts the corners of the mouth in expressions of fear and anger.
Cortico-cortical efferents of primary motor and somatosensory regions of the cerebral cortex in Macaca fascicularis
TLDR
The relationship between primary sensorimotor regions and the cingulate, opercular and insular cortex was discussed, and the implications of the predominant precentral input to area 5 were considered.
Precentral cortical zones related to flexion and extension in two hindlimb movements in the monkey
TLDR
Data suggest that relatively complex muscle synergies may be represented in the precentral cortex of alert rhesus monkeys while each performed two separate leg movements involving both legs and an ankle flexion-extension movement by the leg contralateral to the cortex studied.
Columnar distribution of cortico-cortical fibers in the frontal association, limbic, and motor cortex of the developing rhesus monkey
TLDR
The distinctness of the spatially segregated pattern of innervation in the cortex of neonates indicates that the columnar organization of association-fiber systems in the frontal and limbic cortex is achieved before or shortly after birth.
Activity of primate precentral neurons during voluntary movements triggered by visual signals
TLDR
The wrist (F-E) population showed significantly less response variability than the non-wrist (F)-E population with regard to response latencies to visual signals and movement onsets, and the degree of correlation between duration of response and reaction time.

TLDR
Adult dogs and puppies ranging in age from 1 day up to 3 months the functional organization of the motor cortex has been investigated with 50 or 60 cycle a-c stimulation under Nembutal anesthesia, suggesting that the process of maturation of cortical motor areas were not yet completed at this age.
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
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.
Projections of pyramidal tract cells to alpha‐motoneurones innervating hind‐limb muscles in the monkey.
TLDR
The results give further evidence for overlapping of areas of cortical projections to motoneurones and speak against a mosaic‐like organization of pyramidal tract cells projecting to different motor nuclei.
