Visual functions in a patient with acquired achromatopsia Subjectively, he reports that colours appear abnormal to him and his descriptions of surface colours are similar to those of other patients who suffer cerebral achromatopsia. His colour matching and two colour increment threshold data establish that his cone photoreceptors have normal spectral resp饶舌的人 发表于 2025-3-23 14:38:52
The effects of sub-cortical and cortical damage on colour visionnt retinal units, at the ganglion cells or optic nerve fibres, abolishes all aspects of colour vision. Conversely, cortical lesions of primate visual area V4 affect only one aspect of colour vision, namely colour constancy leaving colour discrimination and simple categorization intact.

The red-green chromatic system in X-chromosome- linked anomalous trichromatsdetection thresholds and hue identification thresholds on a white pedestal. Detection sensitivity functions for wavelengths greater than 500 nm showed two peaks and a notch around 570 nm (PA and N) or 580 nm (DA). The peaks of the function for the two anomalous trichromats were much less sensitive a陈列 发表于 2025-3-24 18:20:14

In early and in mild cases, in which retinal function as judged by quantitative perimetry, threshold measurement and electroretinography is normal or nearly normal, there is a profound loss o
