Selectivity for the shape, size, and orientation of objects for grasping in neurons of monkey parietal area AIP.
TLDR
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. Expand
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. Expand
Grasping objects: the cortical mechanisms of visuomotor transformation
TLDR
In humans, neuropsychological studies of patients with lesions to the parietal lobule confirm that primitive shape characteristics of an object for grasping are analyzed in theParietal lobe, and also demonstrate that this 'pragmatic' analysis of objects is separated from the 'semantic' analysis performed in the temporal lobe.

Neural mechanisms of visual guidance of hand action in the parietal cortex of the monkey.
TLDR
A conceptual model of the system for visual guidance of hand action including parietal hand manipulation neurons is proposed, suggesting that these neurons play an important role in matching the pattern of hand movement to the visuo-spatial characteristics of the object to be manipulated. Expand
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. Expand
Parietal neurons represent surface orientation from the gradient of binocular disparity.
TLDR
The results suggest that neurons that show surface orientation tuning for the RDS without perspective cues compute surface orientation from the gradient of the binocular disparity given by the random-dot across the surface. Expand
Deficit of hand preshaping after muscimol injection in monkey parietal cortex
TLDR
The results suggest that area AIP plays a crucial role in the visual guidance of goal-directed hand movements. Expand
The TINS Lecture The parietal association cortex in depth perception and visual control of hand action
TLDR
The dorsal visual pathway is divided into at least two subsystems, V5A, PP and VIP areas for motion vision and V6, LIP and cIPS areas for coding position and 3-D features. Expand
Neural coding of 3D features of objects for hand action in the parietal cortex of the monkey.
TLDR
Binocular visual neurons in the lateral bank of the caudal intraparietal sulcus (c-IPS area) that preferentially respond to a luminous bar or place at a particular orientation in space are found. Expand
