The Brain

Use of DBS extends beyond what are typically referred to as “movement disorders,” for which issues of motor control are paramount; currently approved for treatment of refractory obsessive-compulsive disorder (OCD) disorder, DBS is expected to gain approval as a treatment for epilepsy as well. Indeed, no neurological or psychiatric disorder ought to be excluded a priori from consideration as a potential indication for DBS. Post-operative management of DBS for these other disorders will benefit from a better understanding of the mechanisms of action. An understanding of the ways in which the brain responds to DBS (see Chapter 6—Nervous System Responses to DBS) related to motor control may therefore serve as an important metaphor for understanding the use of DBS for other conditions.

Technical Details

We describe several infl uential hypotheses in the field of motor control including the equilibrium-point (referent confi guration) hypothesis, the uncontrolled manifold hypothesis, and the idea of synergies based on the principle of motor abundance. The equilibrium-point hypothesis is based on the idea of control with thresholds for activation of neuronal pools; it provides a framework for analysis of both voluntary and involuntary movements. In particular, control of a single muscle can be adequately described with changes in the threshold of motor unit recruitment during slow muscle stretch (threshold of the tonic stretch reflex). Unlike the ideas of internal models, the equilibrium-point hypothesis does not assume neural computations of mechanical variables. The uncontrolled manifold hypothesis is based on the dynamic system approach to movements; it offers a toolbox to analyze synergic changes within redundant sets of elements related to stabilization of potentially important performance variables. The referent confi guration hypothesis and the principle of abundance can be naturally combined into a single coherent scheme of control of multi-element systems. A body of experimental data on healthy persons and patients with movement disorders are reviewed in support of the mentioned hypotheses. In particular, movement disorders associated with spasticity are considered as consequences of an impaired ability to shift threshold of the tonic stretch reflex within the whole normal range. Technical details and applications of the mentioned hypo theses to studies of motor learning are described. We view the mentioned hypotheses as the most promising ones in the field of motor control, based on a solid physical and neurophysiological foundation.
