Somatosensory evoked potentials elicited by lingual nerve stimulation

Objective: Lingual somatosensory evoked potentials are rarely used in clinical practice. For these rare investigations and particularly for forensic questions, however, a standardised method and normative data are essential. To our knowledge, only two groups have published normative data with small numbers of probands until today (Altenmüller et al. 1990 (n=20), Maloney et al. 2000 (n=5)). Methods: Twentyfive healthy subjects (48.3±14.2 years, range 22–70; 16 female) were investigated. After unilateral tongue stimulation, potentials up to 50 msec via electrodes placed on the scalp (C5/6) with a frontocentral ref…
