Abstract
Deep brain stimulation (DBS) has provided remarkable benefits for
people with a variety of neurologic conditions. Stimulation of the
ventral intermediate nucleus of the thalamus can dramatically relieve
tremor associated with essential tremor or Parkinson disease (PD).
Similarly, stimulation of the subthalamic nucleus or the internal
segment of the globus pallidus can substantially reduce bradykinesia,
rigidity, tremor, and gait difficulties in people with PD. Multiple
groups are attempting to extend this mode of treatment to other conditions.
Yet, the precise mechanism of action of DBS remains uncertain. Such
studies have importance that extends beyond clinical therapeutics.
Investigations of the mechanisms of action of DBS have the potential
to clarify fundamental issues such as the functional anatomy of selected
brain circuits and the relationship between activity in those circuits
and behavior. Although we review relevant clinical issues, we emphasize
the importance of current and future investigations on these topics.
