This study was undertaken to determine the topographic organization of connections between the forelimb representations of the ventral premotor cortex (PMv) and the primary motor cortex (M1). Intracortical microstimulation techniques were used in three experimentally naive squirrel monkeys to delineate the M1 and PMv forelimb representations in the hemisphere contralateral to the dominant hand. Small amounts of biotinylated dextran amine (BDA) were then injected in the PMv distal forelimb… Expand
Interhemispheric connections of the ventral premotor cortex in a new world primate
TLDR
The pattern of interhemispheric connections of the ventral premotor cortex (PMv) distal forelimb representation (DFL) in squirrel monkeys is described to provide an anatomical foundation for understanding PMv's role in motor control of the hand and interhemipheric interactions that may underlie the coordination of bimanual movements.

Different Patterns of Cortical Inputs to Subregions of the Primary Motor Cortex Hand Representation in Cebus apella
TLDR
The results of the present work support that the M1 hand representation is composed of several subregions, each part of a unique cortical network. Expand
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). Expand
Origins of multisynaptic projections from the basal ganglia to the forelimb region of the ventral premotor cortex in macaque monkeys
TLDR
Findings indicate that the ventral premotor cortex receives diverse signals from the primary motor, higher‐order motor and limbic territories of the BG. Expand
Thalamic connections of the dorsal and ventral premotor areas in New World owl monkeys
TLDR
Comparisons of thalamic projections to premotor and M1 indicate that both regions receive strong projections from VLx and VLa, with the populations of cells projecting to M1 located more laterally in these nuclei. Expand
Parallel Cortical Networks Formed by Modular Organization of Primary Motor Cortex Outputs
TLDR
The view that primates split the cortical real estate of M1 into modules, each preferentially interconnected with a particular cortical area within the sensorimotor network could sustain parallel processing of interactions with multiple specialized cortical areas to increase the behavioral repertoire of the hand is supported. Expand
Cortical connections of functional zones in posterior parietal cortex and frontal cortex motor regions in new world monkeys.
TLDR
The dorsal parietal-frontalnetwork involved in reaching was preferentially connected to visual cortex, whereas the more ventral network involved in grasping received somatosensory inputs. Expand
Patterns of cortical input to the primary motor area in the marmoset monkey
TLDR
The results demonstrate that M1 is unified by a consistent pattern of major connections, but also shows regional variations in terms of minor inputs, which likely reflect requirements for control of voluntary movement involving different body parts. Expand
Contrasting Modulatory Effects from the Dorsal and Ventral Premotor Cortex on Primary Motor Cortex Outputs
TLDR
Study of the patterns of modulation from PMd within the same and in the opposite hemisphere on the outputs of M1 and compared them with those from PMv found that PMd and PMv have strikingly different effects on M1 outputs. Expand
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.

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
It appears that the differences in the corticocortical inputs contribute to specialization of the PMd and PMv for their differential roles in motor control. Expand

TLDR
The cortical connections of the dorsal (PMd) and ventral (PMv) subdivisions of the premotor area (PM, lateral area 6) were studied in four monkeys through the use of retrograde tracers, finding PMv and PMd appear to be parts of separate, parallel networks for movement control. Expand

Input organization of distal and proximal forelimb areas in the monkey primary motor cortex: A retrograde double labeling study
TLDR
TheForelimb area of the primary motor cortex receives both segregated and intermixed inputs from cortical and subcortical sources, indicating possible different functional roles of frontal premotor areas in control of coordinated distal and proximal forelimb movements. Expand

The results argue against the existence of a second, major noncontiguous distal or proximal forelimb representation located medially within the macaque M1 representation. Expand

TLDR
It is suggested that a large source of variability found in the topography of motor maps in this and other studies derives from differences in the way particular movements and/or movement combinations are performed by individual animals. Expand
Multiple corticospinal neuron populations in the macaque monkey are specified by their unique cortical origins, spinal terminations, and connections.
TLDR
Recognizing a number of separate populations of corticospinal neurons in the frontal, parietal, and insular cortex, each with unique thalamic and cortical inputs, and each of which has continuous access to all spinal motoneuron populations, underlines the importance of cortical and spinal connections linking them and coordinating their action.

Functional specialization in dorsal and ventral premotor areas.
TLDR
This chapter describes attempts to find differences in the use of these two areas in a nonhuman primate for programming future motor actions based on visual signals and shows that neurons in the PMv are involved primarily in receiving visuospatial signals and in specifying the spatial location of the target to be reached.

Two separate regions within area 4 that send corticospinal projections primarily to the lower cervical segments are found that are located within the classical “hand” area of the primary motor cortex and in the PMd. Expand
