Document Summary
Chapter 4 review: the visual cortex and beyond. By the end of this chapter, you should know about: Optic nerve: bundle of retinal ganglion cells that leaves the eye at the retina. Optic tract: a bundle of axons that runs from the chiasm to the lateral geniculate nuclei. Visual field: what you actually see, not what is projected into/out of the eye. Each retina has a nasal section and a temporal section. The right visual field goes to the right nasal retina and the left temporal retina, vice versa for left visual field. We have information coming out of nasal retinal ganglion axons and temporal retinal ganglion axons. They are segregated as they leave the eye they all leave via the optic nerve, but the nasal and temporal axons leave separately. Temporal information stays to the same side of the brain (ipsolateral) Nasal information crosses to the opposite side of the brain via the optic chiasm (contraleral)
