Abstract
Research from macaque neurophysiology and human neuropsychology has
implicated the parietal cortex in the sensory control of action.
Functional neuroimaging has been very valuable in localizing and
characterizing specific regions of the human brain involved in
visuomotor actions involving different effectors, such as the eyes,
head, arms and hands. Here, we review the areas discovered by human
neuroimaging, including the putative functional equivalents of the
following macaque regions: parietal eye fields (PEF), ventral
intraparietal (VIP) area, parietal reach region (PRR) and the anterior
intraparietal (AIP) area. We discuss the challenges of studying
realistic movements in the imaging environment, the lateralization of
visuomotor function, caveats involved in proposing interspecies
homologies and the limitations and future directions for neuroimaging
studies of visuomotor control. (c) 2005 Elsevier Ltd. All rights
