Shifts in gamma phase-amplitude coupling frequency from theta to alpha over posterior cortex during visual tasks

Shifts in gamma phase-amplitude coupling frequency from theta to alpha over posterior cortex during visual tasks

The phase of ongoing theta (4-8 Hz) and alpha (8-12 Hz) electrophysiological oscillations is coupled to high gamma (80-150 Hz) amplitude, which suggests that low frequency oscillations modulate local cortical activity. While this phase-amplitude coupling (PAC) has been demonstrated in a variety of t...
