Using a macroscopic approach we discuss appropriate minimal models to describe a performance of bimanual rhythmic movements. As a paradigm of such movements, a 3:4 polyrhythm is considered. An analysis of experimental data on the basis of symbolic transformation shows tempo-induced qualitative transitions. In attempting to get insights into the control mechanisms of the central nervous system behind these transitions, a model of the control system has been suggested. Two versions of the model, with discrete and continuous time are considered and both of them are in good correspondence with experimental data. Important ingredients of the model are time delay, nonlinear error correction and noise. © 2000 American Institute of Physics.

    Previous research suggests that synchronous cortical gamma-band oscillations reflect the implementation of cognitive control in anticipation of the need to overcome prepotent responses. These studies often require participants to link task instructions with task cues signaling the need (or lack...

    Performance in the stop-signal paradigm involves a balance between going and stopping, and one way that this balance is struck is through shifting priority away from the go task, slowing responses after a stop signal, and improving the probability of inhibition. In 6 experiments, the authors...
