Abstract
We investigated phase dynamics of sinusoidal forearm tracking with delayed visual feedback. To this end we introduced two data analysis tools which enabled us to find several delay-induced transitions between qualitatively different regimes. Our results show that the investigation of delay-induced transitions of the phase dynamics in tracking movements provides us with insights into the underlying neuronal signal processing. In particular, we experimentally verified predictions of a recently presented mathematical model [P. Tass, A. Wunderlin, and M. Schanz, J. Biol. Phys. 21, 83 (1995)].
