摘要：
Strong coherence around 20 Hz is known to exist between the magnetoencephalogram (MEG) recording the primary motor cortex and the contralateral electromyogram (EMG) during isometric muscle contraction. Here we apply a temporal decorrelation technique to identify the underlying brain areas producing signals coherent with the EMG. The algorithm chosen, the temporal decorrelation source separation (TDSEP), exploits efficiently the temporal structure present in the data.
