"ventral pathway, leading from V1 to V2 to V4 and into the inferior temporal lobe; thought to be responsible for colour perception, object recognition and high-resolution perception"
"dorsal pathway, leading from V1 to V2 to V5/MT (middle temporal) and into the parietal lobe; thought to be responsible for spatial vision such as motion and positioning"
"afferents from the temporal (lateral) half of the ipsilateral retina and from the nasal (medial) half of the contralateral retina corresponding to the same side of the visual field innervate the visual cortex on the same side; in simpler terms: the right side of the visual field is represented by the left occipital hemisphere and vice versa"
"Lesions in the primary visual cortex result in a complete loss of visual awareness although some patients retain a degree of functional vision called 'blindsight'. These patients are able to discriminate the presence, location and movement of objects under forced-choice conditions despite reporting no awareness of them 4."
