Table 1.
Summary of all injections. Each injection is listed in the temporal order in which it was performed. Mnk: the animal in which the injection was performed. AC plane: distance from the injection site (in mm) anterior (+) or posterior (−) to the anterior commissure.

symbols identify repeat injections at the same location.
Underlines: injection sites where microstimulation elicited movements of the arm during previous microelectrode mapping.
Func. territory: SM=skeletomotor; Assoc=associative; Limb=limbic. Contralateral arm effects and Ipsilateral arm effects identified by type (DT = prolonged dwell times, RT = prolonged reaction times, MD = prolonged movement duration), magnitude (as percent increase relative to pre-injection mean), and significance level (p value). NT in the Ipsilateral arm column indicates experiments in which the animal performed the task with the contralateral arm only.
