EEG Study of Cortical Dynamics in Dystonia


About this study

The aim of this protocol is to design a measurement paradigm that reliably detects EEG oscillatory patterns during movement, relaxation, or imagination.  These techniques will be applied to normal controls and dystonic patients to define differences in the patterns between the two groups.
