Online identification of functional regions in deep brain stimulation based on an unsupervised random forest with feature selection

Objective. The identification of functional regions, in particular the subthalamic nucleus, through microelectrode recording (MER) is the key step in deep brain stimulation (DBS). To eliminate variability in a neurosurgeon's judgment, this study presents an online identification method for identifying functional regions along the electrode trajectory. Approach. Functional regions can be identified through offline clustering and online...
