Abstract

The phenomenon of blindsight the manifestation by forced-choice guessing of visual processing despite the total loss of visual awareness caused by damage to striate cortex (V1) [1] has influenced many current theories of visual awareness [2,3]. We have investigated whether hemianopic subject GY is able consciously to experience colour in his blind field by using a TMS-chromatic adaptation paradigm, in which TMS applied after visual adaptation to a coloured background preferentially facilitates the perception of the adapted attribute [4]. Our results show that GY can perceive colour in his blind field, and that the identity of the colour is determined by the contralesional hemisphere.
