'Good and bad beta in the basal ganglia'

Recent evidence from depth recordings in patients suggests that beta synchrony across neural populations occurs in bursts, and specific characteristics of these bursts determine whether they promote or impede motor processing. This has a direct bearing on how best to deliver deep brain stimulation. Hitherto this has been delivered continuously, but the indiscriminate suppression of both good and bad beta activity has restricted the therapeutic window. This can be rectified by more selective stimulation.
