Table 1.

Maximizing the average selective activation of the neural populations below IC threshold. There were no stimulation settings that exclusively activated GPi. The combined columns depict the maximal total activation of both GPi and STN concurrently. Each average activation percentage is followed by the standard error of the mean. The individual stimulation settings that achieved those activations are listed within brackets.

Stimulation type	Neural populations activated (%) [stimulation setting] (mA)
	STN only	Combined
	STN only	GPi	STN
One contact (single source)	10.0 ± 1.2 [0, 0, 0, −2]	39.2 ± 3.9 [0, 0, −4, 0]	46.8 ± 4.8
Two contacts (single source)	25.2 ± 3.0 [0, −1, −1, 0]	44.7 ± 4.0 [0, 0, −3, −3]	50.8 ± 4.2
Two contacts (two independent sources)	33.5 ± 3.1 [0, −2, 4, 0]	50.7 ± 3.1 [0, 0, −4, −2]	55.1 ± 4.4
