Fig 5. Ex vivo voxel based morphometry identified areas of significant enlargement in trained animals relative to controls.

These were located in the contralateral (left) M1, S1, S2, CPu, amygdala (Amy), as well as the visual (V1) and entorhinal cortex (Ent). Results are presented as tmaps, FDR cluster-corrected for multiple comparisons using an initial cluster forming threshold of 0.05 significance and the whole brain as a mask (orange color). Uncorrected statistical maps (yellow), suggested involvement of the ipsilateral hemisphere as well, and a role for the hippocampus.
