Areas supplied by the anterior cerebral artery include
- The medial surface of the frontal and parietal lobes
- The anterior four- fifths of the corpus callosum
- Approximately 1 inch of the frontal and parietal cortex
- Anterior portions of the basal ganglia and internal capsule
[edit] Occlusion
Occlusion of the anterior cerebral artery may result in the following defects
