Precision neuroimaging of repeatedly scanned individuals receiving deep brain stimulation (DBS), conducted longitudinally with long scanning durations, revealed separate globus pallidus and motor cortex (M1) circuits with distinct frequency- and time-dependent responses. DBS also evoked divergent effects in M1 functional connectivity, normalizing within the somato-cognitive action network but denormalizing in effector motor networks.

This paper reports that variable-frequency DBS (alternating between 130 and 60 Hz) can improve freezing of gait in Parkinson’s disease, a symptom that is often unresponsive to high-frequency DBS.
