FMRI evidence for a parietal reach region in the human brain

Abstract Event-related functional magnetic resonance
imaging was used to examine activation in the posterior
parietal cortex when subjects made pointing movements
or saccades to the same spatial location. One region, well
positioned to be homologous to the monkey parietal reach
region (PRR), responded preferentially during memory-
delay trials in which the subject planned to point to a
specific location as compared to trials in which the
subject planned to make a saccade to that same location.
We therefore conclude that activation in this region is
related to specific motor intent; i.e. it encodes information
related to the subject's intention to make a specific
