Fig. 4. Deep brain activation in participant subset.

Deep brain activity measures during the seated-walking versus seated-rest task, after repositioning the AMPET helmet lower around the head for a subset (n = 4) of the participants. a, b Activity in two example participants’ axial slices showing activity in deep brain regions, including overlaid a priori anatomical ROIs of the caudate, putamen and thalamus. c Charts showing average (mean ± SE) activity in various deep brain versus cortical ROIs. Error bars represent standard error. Source data is in Supplementary Data 4. See Supplementary Table 1b for exact p values for all comparisons.
