Abstract
Objective: Deep brain stimulation can be a remarkably effective treatment for Parkinson's disease and other conditions; however, an electrophysiological feedback signal is needed to improve surgical accuracy and for optimising therapy according to patient needs. Evoked responses may provide such a signal, although it is crucial to determine that recorded potentials are of neural origin and not a consequence of stimulation artefacts. Here, we use several in vitro and in vivo methods to establish the neural basis of resonant deep brain stimulation evoked activity. Approach: Recordings were obtained from deep brain stimulation electrodes in saline, in feline brain regions not expected to produc..
