Frequency-dependent reciprocal modulation of verbal fluency and motor functions in subthalamic deep brain stimulation.


BACKGROUND High-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor functions in those with Parkinson disease but may worsen frontal functions such as verbal fluency (VF). In contrast, low-frequency DBS leads to deterioration of motor functions. It is not known whether low-frequency STN DBS also has an effect on frontal… (More)
