habenular nucleus

A small set of nuclei in the limbic system found just rostral to the pineal gland in the roof of the third ventricle. The habenula receives axons from the limbic forebrain via a compact tract, the stria medullaris. In turn, the habenula sends a compact bundle of axons, the fasciculus retroflexus (habenulo-interpeduncular tract), to innervate the interpeduncular nuclei of the midbrain.
