The Four Lobes and Major Fissures of the Cerebral Cortex

The Fissures
The fissures are not so much systems of their own as they are marking points between the various lobes of the brain.

Occipital Lobe
The Occipital Lobe is almost entirely used for initial visual reception, which it then passes to the temporal and parietal lobes.

Temporal Lobe
The temporal lobe receives some secondary visual and auditory transmissions from the occipital lobe. It is most often associated with determining what an object is when that object is perceived visually. Visual information received via cones (color and detail) is generally processed here.

Parietal Lobe
The parietal lobe is a somatosensory cortex, and a secondary visual processor. While the temporal lobe is responsible for what an object is, the parietal lobe is instead responsible for determining where an object is located. It's also necessary for comprehending motion and used in other higher functions (such as performing calculations and reading maps).

Frontal Lobe
The Frontal Lobe is responsible for most higher-level functions, including motor control and higher thought functions.
