Pericallosal artery

Looks like

The continuation of the anterior cerebral artery, hugging the top of the corpus callosum, the bridge between the two brain halves.

What it does

Supplies the corpus callosum and the inner surface of the frontal and parietal lobes.

Keeping it well

An aneurysm can form where it gives off the callosomarginal artery; a stroke here causes leg weakness and apathy.
