"The subthalamic nucleus receives its main input from the lateral pallidum (external segment of the globus pallidus). Excitatory, glutamatergic inputs come from the cerebral cortex (particularly the motor cortex), and from the pars parafascicularis of the central complex. There are also neuromodulatory inputs from the substantia nigra pars compacta."
