Document Summary
Reading 14: object vision and spatial vision two cortical pathways . Ventral interconneccting the striate, prestriate, and inferior temporal areas. Dorsal interconnecting the striate, prestriate, and inferior parietal areas. Allows us to determine the visual location of objects. Tissue essential for vision extends far beyond the striate cortex to include not only the pre-striate cortex of the occipital lobe, but also large portions of the temporal and parietal lobes. Recent work suggests that these multiple visual areas are organized hierarchically into two separate cortical visual pathways one specialized for object vision, the other for spatial vision. Occipito-temporal projection system that follows the inferior longitudinal fasciculus. Subsequent links of the occipitotemporal pathway with limbic structures in the temporal lobe and with ventral portions of the frontal lobe may make possible the cognitive association of visual objects with other events, such as emotions and motor acts. Occipito-parietal projection system that follow the superior longitudinal fasciculus.
