PMID-14960502[0] Event-related beta desynchronization in human subthalamic nucleus correlates with motor performance.
- Asked 6 PD patients to play a game where they were warned to move / not to move.
- Beta-frequency (20hz) power decreased prior to movement, with a time course correlated to reaction time.
- This was followed by a late post-movement increase in beta power.
- No-go trials showed a brief dip in beta power, with quick resumption.
- conclude that:
- the subthalamic nucleus is involved in the preparation of externally paced voluntary movements in humans
- the degree of synchronization of subthalamic nucleus activity in the beta band may be an important determinant of whether motor programming and movement initiation is favored or suppressed. (hum, maybe).
- found via Romulo's references; see the list of papers that cite it.
