In which part of the brain is vision primarily processed?

Vision is primarily processed in the occipital lobe of the brain, which is located at the back of the head. This region contains the primary visual cortex, where visual information received from the eyes is interpreted and integrated. The occipital lobe takes raw data from visual stimuli, such as light and color, and transforms it into a coherent visual representation, allowing us to recognize shapes, movement, depth, and color.

The other areas of the brain serve different functions. The frontal lobe is primarily responsible for higher cognitive functions, such as reasoning, decision-making, and voluntary motor activity; the parietal lobe is involved in processing sensory information and spatial awareness; and the temporal lobe plays a crucial role in auditory processing and memory, along with some aspects of visual perception, but not the primary processing of visual information. Therefore, the designated role of the occipital lobe in visual processing makes it the correct answer.
