Function

The function of the STN is unknown, but current theories place it as a component of the basal ganglia control system that may perform action selection. STN dysfunction has also been shown to increase impulsivity in individuals presented with two equally rewarding stimuli.

Research has suggested that the subthalamus is an extrapyramidal center. It holds muscular responses in check, and damage may result in hemiballismus (a violent flinging of the arm and leg on one side of the body).
