From: Non-invasive detection of language-related prefrontal high gamma band activity with beamforming MEG

Individual beamformer results. High gamma ERSs induced by the verb generation task were detected in eight of the fifteen participants using the beamformer method. (a) High gamma ERSs were detected in the left MFG (BA 46) at 550–750 ms. (b) No high gamma ERSs were detected in the left BA 46 at 550–750 ms.
