The eye is the sense organ that detects stimulus, or light. The retina is in the back of the eye and is responsible for converting electromagnetic energy into neural impulses to be processed by the brain. There are two types of receptor cells in the retina, which are rods and cones. Rods are sensitive to light and work best in dim lighting, but are not useful for color vision. On the contrary, cones are what we use for color perception. The cones are …show more content…
The optic nerve carries the visual stimuli to the thalamus, where it is sorted and sent to the correct place in the brain for interpretation. The thalamus is in the forebrain at the top of the brain stem, and it is from there that the information is transferred to the visual cortex in the occipital love at the back of the brain. Light travels in a straight line into the eye. Therefore, any stimuli registered on the right side of the eye is sent straight to the left side of the brain. This works the same way for the left eye, meaning that any light registered on the left side of the eye will be sent to the right side of the
