The anterior cornu (frontal horn, anterior horn; precornu) passes forward and lateralward, with a slight inclination downward, from the interventricular foramen into the frontal lobe, curving around the anterior end of the caudate nucleus.
Its floor is formed by the upper surface of the reflected portion of the corpus callosum, the rostrum.
It is bounded medially by the anterior portion of the septum pellucidum, and laterally by the head of the caudate nucleus.
Its apex reaches the posterior surface of the genu of the corpus callosum.
