Fig. 1.

Locations of recording and stimulation sites surrounding central sulcus (CS). White surface corresponds to the boundary between cortex and underlying white matter. View is along the CS from the right side of the monkey looking towards the midline and slightly posterior. Dashed black lines indicate the bottom of the intraparietal (IPS) and arcuate sulci (AS). Red spheres indicate recording sites containing neurons with tactile properties, blue represents proprioceptive, and yellow represents motos sites. Large spheres represent those sites used in the stimulation experiments.
