Figure 9.

Four magnified brain maps to show stimulation resulting in motor movement along with the activation for the same modality. Stimulation is done pairwise; thus, elicited motor movement may be attributable to cortex beneath only one of the electrode pair. Positive electrode stimulation locations are shown with green triangles connected by jagged green lines. The top cortex of each pair is the high-frequency representation, and the bottom is the low-frequency representation. A, B, Hand movements with stimulation are shown for patients 16 (A) and 6 (B). C, D, Tongue movements are shown for patients 1 (C) and 3 (D). Please see the supplemental discussion (available at www.jneurosci.org as supplemental material) regarding the stimulation process.
