Explanation:

The occipital lobe is one of the smallest brain lobes, and occupies a small portion of the back of the brain, between the cerebellum, the temporal lobe and the parietal lobe.

The function that best describes the activity of the occipital lobe is the processing of visual information.  In fact, the main function of this region of the cortex is to receive stimuli related to the optic pathway, which come in the first instance from the optic nerves and, in the second instance, from other subcortical structures.

In this sense, the occipital lobe comprises the visual cortex, which is the area of the cortex of the brain to which the information that comes from the retinas of the eyes and the optic nerves first comes in.
