From: Single reach plans in dorsal premotor cortex during a two-target task
Experimental setup. a Monkeys used a planar manipulandum to control a cursor. b Array placement in dorsal premotor (PMd) and primary motor (M1) cortex (CS central sulcus, AS arcuate sulcus, PCD precentral dimple, IPS intraparietal sulcus). Dashed lines correspond to approximate locations of sulcal landmarks that were obscured by the boundaries of the intraoperative craniotomy. c Task events during 2-Target trials and resulting cursor trajectories. The monkeys were initially presented with two opposing targets. On most trials (top), the correct target was displayed at the start of the Cue epoch; roughly 10% did not contain a Cue epoch (Free-Choice, bottom). On these trials, the monkeys were forced to select one of the two targets with no information about which would lead to reward. d Same as in c for 1-Target trials. The monkey image in a was created by Paul Wanda for use in this paper. All rights reserved
