Blood supply to the cerebral cortex is part of the [[cerebral circulation]]. [[Cerebral arteries]] supply the blood that [[Perfusion|perfuses]] the cerebrum. This arterial blood carries oxygen, glucose, and other nutrients to the cortex. [[Cerebral veins]] drain the deoxygenated blood, and metabolic wastes including carbon dioxide, back to the heart.

The main arteries supplying the cortex are the [[anterior cerebral artery]], the [[middle cerebral artery]], and the [[posterior cerebral artery]]. The anterior cerebral artery supplies the anterior portions of the brain, including most of the frontal lobe. The middle cerebral artery supplies the parietal lobes, temporal lobes, and parts of the occipital lobes. The middle cerebral artery splits into two branches to supply the left and right hemisphere, where they branch further. The posterior cerebral artery supplies the occipital lobes.

The [[circle of Willis]] is the main blood system that deals with blood supply in the cerebrum and cerebral cortex.
