Figure 13. Post-motor theta dynamics. Frame of an animation representing grand mean patterns of event-related dynamics in the theta band. Black traces in the lower panel show the envelope of the grand mean ERP time locked to the subject button press; (dotted vertical line) median time of stimulus onset (response-352 ms). Theta dynamics computed in a window (center frequency 4.87 Hz, 3-cycle Hanning taper) centered (blue vertical line) 89 ms after the button press (red vertical line). Each sphere in the upper panel represents the location of the equivalent dipole for a component cluster. Approximate projections of the equivalent-dipole locations are shown in shadow on three planes from an average MR image (Montreal Neurological Institute). Log spectral power changes (relative to pre-stimulus baseline) are indicated by the sizes of the spheres (see key, bottom right). Non-grey sphere colors indicate consistent inter-trial phase locking (ITC). Colored cylinders joining spheres indicate significant event-related phase coherence (ERC) between cluster components.
