Title: A Hamiltonian approach to motor planning.
Streaming Video: Real Media
A Hamiltonian framework for motor planning is presented that allows for compliant goal-directed (discrete) and repetitive motion. Motor planning among local joint groups can be achieved by trading off potential and kinetic energy. The potential energy is assumed to arise from a combination of external constraints (gravity, external forces), and internally (neuronally) generated components. This formulation is able to account for some symptoms of Parkinson's and Huntington's diseases in terms of defects in the potential energy function. We hypothesize that one component of the neuronally-generated potential energy arises from a diffusion-style computation within the striatum, which is able to integrate the required sensory information and provide guidance for motion execution.
