Document Summary

Damage to right hemisphere, parietal or frontal, give them pictures and ask them to draw, they will only draw the right side of the picture. Patients often only eat food on the right side of their plate and ignore the left. When you ask her to pay attention to something in the left side of space, she understands what we mean but doesn"t know how to do it. Right hemisphere is damaged, and areas in parietal and prefrontal (ones from before) Right visual cortex processes the left visual field and vice versa, each visual cortex processes contralateral visual field. To get beyond visual and into parietal and prefrontal it isn"t so straight forward, we see the left hemisphere still processes right side, but the right hemisphere generally is really good at spatial tasks. Left side only processes contralateral, while right side processes both sides (bilateral) Neglect is not a deficit in vision, but a deficit in spatial awareness.
