Phase coupling in the beta and gamma frequencies of motor cortex activity is elevated in people with Parkinson's disease when medication is temporarily withheld.

OBJECTIVE: How neuronal oscillatory activity in Parkinson's disease (PD) is organized and coordinated is not yet known. We hypothesized that cross-frequency phase synchrony (CFS) in the beta and gamma frequencies measured over the motor cortex [using…
