Locations of equivalent current dipoles (ECDs) in the posterior cingulate cortex induced by cue sounds and imagery of handgrips during the second magnetoencephalography (MEG) sessions.

<p>Closed red circles indicate the locations of ECDs and short red lines radiating from closed circles indicate the orientation of ECDs. ECDs are superimposed on individual magnetic resonance images (sagittal view) (A: anterior side; P: posterior side). The peak latencies are presented in parentheses.
