Acquired cerebral dyschromatopsia
G. J. Green and S. Lessell
Color blindness developed in five patients apparently because of lesions in
the posterior portions of both cerebral hemispheres. Three of them also had
symptoms of prosopagnosia. The lesions were neoplastic in two and vascular
in three of the patients. It would appear that bilateral, inferior,
occipital lobe lesions may be responsible both for acquired cerebral
dyschromatopsia and prosopagnosia. Evidence from experimental
investigations in primates suggests that the areas of the cerebral
hemispheres analogous to those involved in these patients, may be
specialized for the processing of colored stimuli.
