1. Modulation of high γ activity in different brain regions is correlated with behavior.
Modulation of high γ activity in different brain regions is correlated with behavior. A, Localization of the stimulation sites in the lateral TC (red contact pairs) and the other three brain regions studied (black contact pairs) is visualized in a unified transparent brain surface. B, Stimulation-induced change in memory performance for every subject (each bar is one subject) reveals that stimulation in the TC had a positive effect on performance compared to the other brain regions (PF). Post hoc group comparison (right side) shows that TC scores are greater than PH, HP, PF (dashed lines are 95% CI of the TC group). C, NM index values reveal the same pattern as in B, averaged from all active electrodes in a given group [n = 38 (PH), n = 80 (HP), n = 36 (TC), n = 44 (PFC)]. D, The behavioral and NM index scores averaged for each subject (color-coded dots) are correlated. Least-square line is added in black, crossing the two dashed lines at point 0 indicating no stimulation-induced changes.
