Where is the habenula in the brain?
The habenula is an ancient brain structure that is conserved in virtually all vertebrate species1,2. In mammals, it consists of a pair of small nuclei located at the posterior–dorsal–medial end of the thalamus and can be divided into the medial habenula (MHb) and lateral habenula (LHb) regions2 (Fig.
Is the habenula in the midbrain?
Medial habenula primarily receives inputs from the medial and lateral septal nuclei. Its output is almost entirely to the interpeduncular nucleus of the midbrain.
Is habenula part of hypothalamus?
Finally, the third part, which lies below the hypothalamic sulcus, forms the hypothalamus. Thus, some authors define the epithalamus as part of the diencephalon, comprising part of the habenula and the pineal gland.
Is the habenula part of the limbic system?
In the thalamus, the habenular nucleus and the rostral thalamic nucleus function mainly in the limbic system (see Fig. 17-2). The habenular nucleus is part of the epithalamus, located dorsally, adjacent to the third ventricle and rostral to the pineal body (see Fig. 2-4).
Do humans have a habenula?
Anatomical description of Hb in the human brain remains limited. As for the rodent Hb, the human Hb is also located next to the third ventricle above the thalamus, and is approximately 5–9 mm in diameter with a total volume in the 30–36 mm3 range (21) (mouse Hb is 0.8 mm in height and width for comparison (22)).
What is the best definition of habenula?
Anatomy. a narrow bandlike structure, as the stalk attaching the pineal gland to the thalamus.
What is in the lateral habenula?
The primary output regions from the lateral habenula are midbrain aminergic centers, which include the dopaminergic (DA) VTA and substantia nigra pars compacta (SNc), serotonergic (5-HT) dorsal and median raphe (DRN, MRN), and GABAergic rostromedial tegmental nucleus (RMTg, also known as tail-VTA).
