Figure 3. Peri-movement beta ERD and MRGS responses.

Figure 3

Group-averaged beamformer images (pseudo-t) for the peri-movement beta ERD (left panel) and MRGS (right panel) are shown for the congruent and incongruent conditions individually. Images are shown in radiologic convention (R = L). In both conditions, the task induced a strong peri-movement beta ERD in the bilateral primary motor cortices (stronger in the contralateral), and a MRGS response that was restricted to the contralateral primary motor cortex. Virtual sensors were extracted from the peak voxel(s) in the grand average image (congruent and incongruent) of each response, and these time series were used to assess the effects of condition on amplitude and peak frequency.
