Properties of spike train spectra in two parietal reach areas
Published online: 28 August 2003

Abstract In the lateral intraparietal area (LIP), a saccade-
related region of the posterior parietal cortex (PPC),
spiking activity recorded during the memory period of an
instructed-delay task exhibits temporal structure that is
spatially tuned. These results provide evidence for the
existence of `dynamic memory fields' which can be read-
out by other brain areas, along with information contained
in the mean firing rate, to give the direction of a planned
movement. We looked for evidence of dynamic memory
fields in spiking activity in two parietal reach areas, the
parietal reach region (PRR) and area 5. Monkeys made
center-out reaches to eight target locations in an instruct-
