This study explores a machine-learning method to detect evoked resonant neural activity (ERNA) during deep brain stimulation (DBS) in the subthalamic nucleus (STN) of Parkinson’s disease (PD) patients. Utilizing seven binary classifiers and eight time-domain signal features, the approach achieved a 99.1% accuracy, with 99.6% specificity and 98.7% sensitivity in distinguishing ERNA from background neural activity. A signal-to-noise ratio of 15 dB was necessary for maintaining 90% classifier sensitivity. This indicates that detecting ERNA is viable with the right signal processing and feature extraction techniques, suggesting potential for real-time application with further simplification. The ability to detect ERNA accurately is crucial for guiding the placement of DBS electrodes during surgery, offering a significant tool for clinicians to optimize DBS electrode positioning within the STN, enhancing the effectiveness of the procedure for PD patients.
