Localization without content. A tactile analogue of 'blind sight'

Arch Neurol. 1983 Sep;40(9):548-51. doi: 10.1001/archneur.1983.04050080048008.

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."
