Optic nerve pathway to brain

WebA neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex. WebThe Optic Pathway. The optic pathway includes the retina, optic nerve, optic chiasm, optic radiations, and occipital cortex (see figure Higher visual pathways ). Damage along the optic pathway causes a variety of visual field defects. The type of field defect can help localize the lesion (see table Types of Field Defects ).
