Cerebral achromatopsia

Cerebral achromatopsia

What is cerebral achromatopsia and where is the lesion responsible for it? 

Achromatopsia is an acquired lack of color vision.

Lesions of the occipital cortex below the calcarine sulcus produce upper quadrantanopia and achromatopsia in the preserved inferior visual field.

Hemiachromatopsia can result from contralateral inferotemporal lesions of the fusiform and lingual gyri.
