SUMMARY
The posterior parietal cortex (PPC) of rhesus
monkeys has been found to encode the behav-
ioral meaning of categories of sensory stimuli.
When animals are instructed with sensory
cues to make either eye or hand movements
to a target, PPC cells also show specificity de-
pending on which effector (eye or hand) is
instructed for the movement. To determine
whether this selectivity retrospectively reflects
the behavioral meaning of the cue or prospec-
tively encodes the movement plan, we trained
