A Tactile Analogue of 'Blind Sight'

Jacques Paillard, DSc; Francois Michel, MD; George Stelmach, PhD

Arch Neurol. 1983;40(9):548-551.

Abstract
• We examined the ability of a patient, who had a cerebral lesion involving the left posterior hemisphere, to identify and to localize stimuli applied to her "deafferented" right upper limb. We observed a functional dissociation between localization and identification in both performance and subjective report. This finding may be a tactual analogue of "blind sight."
