Specifically, males majoring in physical science tended to rely on a spatial/holistic MR strategy (as evidenced by the significant activation of electrodes over the right parietal area) and also obtained the highest average MRT accuracy.
An additional parietal area displayed pronounced activity as toolmakers gained skills.

Given that the MRT is a visuospatial task then this change in activity should be maximal over the parietal areas. If mental rotation involves motor processes then changes should also be observed over the motor areas of the cortex.
The test was signalized about the onset of the false image perception by raising up the pencil, and a suppression of activity in alpha-band was recorded after the onset of stereo perception was revealed in the frontal areas (Fp1C3, Fp2C4) and in the left parietal area (C3O1) of the cortex.
