The semidecassation is the incomplete crossing of nerve fibers at the optic chiasm which results in each optic tract containing half of the ipsilateral optic nerve and one half of the

In the eyes of both humans and dogs‚ there are two main types of light-sensitive cells referred to as rods and cones. Cone cells enable you to see color. Rods work with black and white vision‚ so they’re better at identifying shades in dim light. Dogs are dichromats‚ which means they possess only two types of cones. This enables their brains to distinguish blue from yellow‚ but not red from green. Humans‚ on the other hand‚ are trichromatic. Our eyes contain three types of light-sensitive cones.
