| Definition: |
Habenular nucleus positioned ventromedially to the dorsal habenular nuclei. The ventral habenular nuclei are paired and symmetrical, each have a conical shape defined by a wide rostral end, occupying the entire anterior region of the habenula, and a narrow caudal end. The axons of the ventral habenular nucleus passed laterally through the interpeduncular nucleus and projected to the ventral part of the median raphe. The ventral habenular nucleus is homolog mammalian lateral habenular nucleus. |
