Visual perception is the product of complex interactions between multiple subdivisions of the brain. 11.2 shows the visual pathways. This site of the optic nerve is called optic chiasm . Once past the optic chiasm, the optic nerve is called optic tract , which contains fibers from both eyes.
Optic tract reach a number of structures in the brain as follows.
This pathway is called retinogeniculostriate pathway or primary visual pathway. Hypothalamus - for regulation of circadian rhythm. Superior colliculus - for orienting movements of head and eyes. 11.4B illustrates the parts in a visual field. Each eye sees a part of visual space that defines its visual field.
