Summary

Depressive symptoms of Parkinson's disease (PD) patients are major predictors of their prognosis and quality of life. Using subthalamic nucleus (STN) deep brain stimulation (DBS) as an antidepressant could be a promising new direction. Existing methods of adjustment of DBS parameters aim at amelioration of the motor signs and therefore with inactivation of the STN motor territory only. Although the DBS parameter setting is believed to influence the mental state, there is no data that correlates stimulation parameters with mental state. The investigators hypothesize that the emotional territories of the STN have distinct electrophysiological properties and that specific stimulation of these emotional territories can influence the mental state and thus treatment with emotionally-adjusted DBS can improve the psychiatric symptoms of PD. In this project, the investigators intend to map the emotional territories of the STN using neuronal (single units) responses to emotional voices and to identify the emotional spectral signature of the STN single unit activity using spectral analysis and neuronal responses to emotional voices. The investigators also intend to investigate the emotional processing of PD patients by manipulating the stimulation of the subthalamic area. The proposed study will combine neural recording, stimulation and psychological tests to shed new light on emotional processing in the basal ganglia, as well as to provide better treatment for PD emotional disorders,
