The subthalamic nucleus (STN) is a small, lens-shaped structure located beneath the thalamus in the brain that plays a crucial role in the regulation of movement and is part of the basal ganglia circuitry. Its primary function is to modulate motor control and has been identified as a target for neuroprosthetic interventions, particularly in cases of movement disorders like Parkinson's disease. Understanding its function and connections is essential for appreciating its impact on neuroprosthetic advancements.
