Monophasic positive scalp somatosensory evoked potential wave in parietal tumors

Abstrakt

The work describes possible mechanisms of the scalp somatosensory positive potential in parietal tumors. Autors consider the shift of primary somatosensory region to be the most likely mechanism.

The shift leads to the change in dipole orientation and subsequently to the change in the somatosensory evoked potential dipole
