Gray Matter

Central Sulcus

The groove that separates the frontal lobe from the parietal lobe.

Precentral Gyrus

The gyrus located before the central sulcus, associated with the primary motor area.

Postcentral Gyrus

The gyrus located after the central sulcus, associated with the primary sensory area.

Primary Sensory Area

The area on the postcentral gyrus where sensory information is processed.

Primary Motor Area

The area on the precentral gyrus where motor commands are generated.

Association Areas

Regions of the brain that connect sensory and motor areas, allowing for coordinated responses.

Integration Areas

Regions of the brain that combine functions from multiple lobes to facilitate complex tasks, such as speech and reading.

Gyrus

A ridge or fold on the surface of the brain.

Sensory Cortex

Part of the brain involved in processing sensory information, found in the parietal lobe.

Motor Cortex

Part of the brain involved in planning, controlling, and executing voluntary movements.
