Brain dynamics of bimanual coordination

Subjects performing bimanual coordination show spontaneous transition from antiphase to inphase as frequency is increased (Kelso, 1984).

We use EEG to understand how the brain performs stable bimanual coordination and why stable patterns of antiphase break down at high movement frequency.

Our investigation addresses 3 questions:

- What are the differences in the organization of motor processing between the two stable states (antiphase and inphase)?

- What neural changes preclude/explain the loss of stability of antiphase at higher frequencies and the transition to inphase?

- How is the neural activity underlying unimanual performance reorganized during the performance of a bimanual inphase or antiphase pattern? What are the additional components specific to the coordinated bimanual movement?

The experimental work is realized in conjunction with the Theoretical Neuroscience Group. For information about modeling of bimanual coordination, follow this link.
