Abstract: We studied instances of mirror movements - in the form of coherent EMG activity of the muscles in the arm not intended to move - during the performance of a unimanual rhythmic task in healthy adults. Epochs of involuntary muscle activity were detected and analyzed using time-resolved spectral methods. The observed frequency and phase locking between EMG patterns derived from homologous extensor muscles indicated the presence of neural cross-talk, which is relevant to the study of interlimb coordination. © 2005 Elsevier Ireland Ltd.
