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