WILLEM-JENTJE ATSMA is an academic who published a paper in 2006 entitled Inference of central nervous system input and its complexity for interactive arm movement. WILLEM-JENTJE ATSMA published this work as part of a team: Atsma, Willem Jentje. Here is a description of this work: This dissertation demonstrates a new method for inferring a representation of the motor command, generated by the central nervous system for interactive point-to-point, movements. This new tool, the input, inference neural network or IINN, allows estimation of the complexity of the motor command. The IINN was applied to experimental data, gathered from 7 volunteer subjects who performed point-to-point, tasks while interacting with a specially constructed haptic robot. The motor plan inference demonstrates that, for the point-to-point movement tasks executed during experiments, the motor command can be projected onto a low-dimensional manifold. This dimension is estimated to be 4 or 5 and far less than the degrees of freedom available in the arm. It is hypothesized that subjects simplify the problem of adapting to changing environmen.
