Parasagittal reconstructions (lateral 5–8) illustrating the sites of focal injections of muscimol in the STN and the resultant improvements in generalized (A) and contralateral forelimb (B) akinesia in two parkinsonian monkeys. The sites producing contralateral circling and atypical behavior are also indicated in Figure A.Open small squares indicate sites with no motor effects, and filled squares, asterisks, andopen circles indicate the levels of changes in postinjection scores from mean baseline scores for akinesia, atypical behavior, and contralateral circling, respectively. The gray shaded regions represent general (A) and specifically, forelimb (B) sensorimotor territories across three monkeys (detailed in Fig. 1B).
