Psychophysical observations after anesthesia of the thumb raise the question whether the functional border between the thumb and the index is functionally distinct. We present a source localization study using equivalent current dipole modeling of somatosensory evoked potentials (SEPs) following mechanical air-puff stimulation of the first, second and third digits before and during anesthesia of the thumb. Source reconstruction was based on 96-channel SEP recordings. During anesthesia of the… CONTINUE READING
