Figure 9.

Box plots showing distribution of the threshold currents required to evoke movements of different body parts in the normal (NM56) and the lesioned (LM98, LM78, and LM01) monkeys. The threshold currents for digit movements (A) were significantly higher for the lesioned monkeys compared with the normal monkey, whereas the currents required to evoke movements of the wrist, shoulder, and facial muscles (B, D, E) were not affected by the lesion. Currents required to evoke movements of the elbow were higher for monkeys LM98, but not for LM78 and LM01 (C). Key to different statistical parameters illustrated in the box plots is shown in F. The dots mark the observations that have been deemed to be outliers by the statistical software (SigmaPlot); however, these values were included while calculating the mean and the median. The total number sites from which the movements of each body part were evoked is shown in brackets for each monkey on the abscissa. ***p < 0.001; **p < 0.01; *p < 0.05.
