N30 and the effect of explorative finger movements : A model of the contribution of the motor cortex to early somatosensory potentials

The source of the N30 potential in the median nerve somatosensory evoked potentials (SEP) has been previously attributed to a pre-central origin (motor cortex or the supplementary motor area, SMA) or a post-central located generator (somatosensory cortex). This attribution was made from results of l...
