How DBS affects information flow along basal ganglia pathways is unclear. Kahan et al. model fMRI data, revealing differences in the neuromodulatory effects of DBS during different behavioural states. The results suggest that DBS has both behaviour-independent effects on basal ganglia connectivity as well as behaviour-dependent neuromodulatory effects.
