1:2 entrainment is not a device-induced artefact, except when it is.
In patients with Parkinson’s, enhanced signals can be measured at half the frequency of deep brain stimulation (DBS). Whether these signals are caused by the device or reflect actual brain processes has been a topic of debate. In this work, we provide evidence supporting a physiological origin for these signals, as well as a checklist which can be used to confirm that the DBS device is not causing these signals. This study is a step towards developing novel biomarkers for more effective DBS treatments.
