The parietal reach region is limb specific and not involved in eye-hand coordination.
Primates frequently reach toward visual targets. Neurons in early visual areas respond to stimuli in the contralateral visual hemifield and without regard to which limb will be used to reach toward that target. In contrast, neurons in motor areas typically respond when reaches are performed using the contralateral limb and with minimal regard to the visuospatial location of the target. The pari...
متن کاملSpatial and temporal eye-hand coordination relies on the parietal reach region.
Coordinated eye movements are crucial for precision control of our hands. A commonly believed neural mechanism underlying eye-hand coordination is interaction between the neural networks controlling each effector, exchanging, and matching information, such as movement target location and onset time. Alternatively, eye-hand coordination may result simply from common inputs to independent eye and...
متن کاملBimanual coordination: an unbalanced field of research.
Using more than one limb to perform functional, goal-directed actions is arguably one of the most important abilities that human beings possess. In many everyday tasks, the hands, in particular, must be used to accomplish all manner of goals. From buttoning a shirt to opening a jam jar and driving to work, good bimanual coordination is of great utility. In addition to the tasks mentioned above,...
متن کاملSaccade-related activity in the parietal reach region.
In previous experiments, we showed that cells in the parietal reach region (PRR) in monkey posterior parietal cortex code intended reaching movements in an eye-centered frame of reference. These cells are more active when an arm compared with an eye movement is being planned. Despite this clear preference for arm movements, we now report that PRR neurons also fire around the time of a saccade. ...
