Neuronal pathways involved in deep brain stimulation of the ...

Abstract - in this study, fixed potential amperometry was used to examine several pathways by which deep brain stimulation (dbs) of the subthalamic nucleus (stn) or dopamine axons within the dorsal forebrain bundle (dfb) release striatal dopamine, thus potentially providing therapeutic Fixed potential amperometry set-up for evaluation of the effects of intra-snc or ppt lidocaine infusions on stn or dfb electrical stimulation
