Optic chiasm

The optic chiasm is the place in the brain where the two visual lines from the two eyes intersect and form the visual nerve that goes to the brain. In humans, there is usually a chiasm in the visual cortex, where image projections from the right and left sides of the brain intersect, giving the brain an idea of ​​how things are arranged in space. If something is damaged in this area, such as in multiple sclerosis, difficulties arise in perceiving and understanding visual images. For example, people may see strange shapes or lose the ability to navigate space and perceive colors in their natural light.
