Somatosensory disinhibition and frontal alien hand signs following medial frontal damage

Shuhei Yamaguchi et al. J Clin Neurosci. 2006 Feb.

Abstract

We report augmentation of somatosensory evoked potentials (SEP) in a patient with frontal alien hand signs after left medial frontal lobe damage. The SEP components occurring later than 30 msec post stimuli were enhanced over the parietal and frontal scalp sites of the lesioned hemisphere. This finding suggests that deficits in inhibitory control of somatosensory processing in parietal and frontal lobes contributes in some way to frontal alien hand signs.
