Selectivity for the shape, size, and orientation of objects for grasping in neurons of monkey parietal area AIP.
The results suggest that the visual responses of object- type neurons represent the shape, size, and/or orientation of 3D objects, whereas those of the nonobject-type neurons probably represent theshape of the handgrip, grip size, or hand-orientation.
The organization of the cortical motor system: new concepts.
Corticocortical connections of area F3 (SMA‐proper) and area F6 (pre‐SMA) in the macaque monkey
The monkey mesial area 6 comprises two distinct cytoarchitectonic areas: F3 [supplementary motor area properly defined (SMA‐proper)], located caudally, and F6 (pre‐SMA), located rostrally, to describe the corticocortical connections of these two areas.
The Cortical Motor System
Cortical connections of the macaque anterior intraparietal (AIP) area.
The identification of direct anatomical connections with the inferotemporal cortex suggests that AIP could represent a crucial node in a cortical circuit in which hand-related sensory and motor signals gain access to representations of object identity for tactile object recognition.
Functional organization of inferior area 6 in the macaque monkey
It is proposed that the different classes of neurons form a vocabulary of motor acts and that this vocabulary can be accessed by somatosensory and visual stimuli.
Coding of peripersonal space in inferior premotor cortex (area F4).
The functional properties of neurons in the caudal part of inferior area 6 (area F4) in awake monkeys are studied and it is concluded that space is coded differently in areas that control somatic and eye movements.
Cortical connections of the inferior parietal cortical convexity of the macaque monkey.
The present data challenge the bipartite subdivision of the IPL convexity into a caudal and a rostral area and provide a new anatomical frame of reference of the macaque IPL conveyxity that advances present knowledge on the functional organization of this cortical sector, giving new insight into its possible role in space perception and motor control.
Functional neuroanatomy of the primate isocortical motor system
An overview of the structure and function of the isocortical part of the motor cortex in the macaque and human brain is given and it is revealed that functional gradients can be discerned within the human non-primary motor cortex.
Multiple representations of body movements in mesial area 6 and the adjacent cingulate cortex: An intracortical microstimulation study in the macaque monkey
Whether the cytoarchitectonic subdivision of the mesial agranular frontal cortex into two areas has a physiological counterpart is investigated by observing the motor responses evoked by their intracortical electrical microstimulation.
