Bottom Line: In parallel with these developments, our ability to build computational models to embody our expanding knowledge of the biophysics of neurons and their networks is maturing at a rapid rate.We present a set of preliminary calculations employing basal ganglia computational models, structured within an unscented Kalman filter for tracking observations and prescribing control.Based upon these findings, we will offer suggestions for future research and development.

ABSTRACT
Modern model-based control theory has led to transformative improvements in our ability to track the nonlinear dynamics of systems that we observe, and to engineer control systems of unprecedented efficacy. In parallel with these developments, our ability to build computational models to embody our expanding knowledge of the biophysics of neurons and their networks is maturing at a rapid rate. In the treatment of human dynamical disease, our employment of deep brain stimulators for the treatment of Parkinson's disease is gaining increasing acceptance. Thus, the confluence of these three developments--control theory, computational neuroscience and deep brain stimulation--offers a unique opportunity to create novel approaches to the treatment of this disease. This paper explores the relevant state of the art of science, medicine and engineering, and proposes a strategy for model-based control of Parkinson's disease. We present a set of preliminary calculations employing basal ganglia computational models, structured within an unscented Kalman filter for tracking observations and prescribing control. Based upon these findings, we will offer suggestions for future research and development.

RSTA20100050F1: A well-marked case of this disease, as described by William Gowers. (Adapted from Gowers (1901).)

Mentions: Parkinson’s disease was first described by James Parkinson in a monograph published in 1817 (Parkinson 1817). It is a degenerative neurological condition, and we attempt to digest the neurological manifestations of this disease into four key signs: tremor, rigidity, bradykinesia (slowness of movement) and postural instability. But a far better sense of the signs of this condition was captured by the short description by William Gowers in his 1901 textbook (Gowers 1901) that flanked his famous sketch of a typical patient walking (reproduced in figure 1)
