Effects of VSOP training on bilateral striatum-prefrontal networks. (A) Bilateral striatum-prefrontal networks at baseline: L = left, R = right. (B) Training-induced changes in striatum-prefrontal networks for the VSOP group: L, left striatum-left inferior prefrontal gyrus (-45, 27, 21); R, right striatum-right middle frontal gyrus (42, 6, 60). No changes were found for the MLA group. (C) Changes in bilateral stratum-prefrontal connectivity from baseline to post-training. Squares show left striatum-prefrontal network. Triangles show right striatum-prefrontal network. Circles show group averages. Error bars are SEM.
