The tuber cinereum is a hollow eminence of gray matter situated between the mammillary bodies and the optic chiasm. The tuber cinereum is part of the hypothalamus.
Structure[]
Laterally it is continuous with the anterior perforated substances and anteriorly with a thin lamina, the lamina terminalis.
The infundibulum, a hollow conical process, projects from the tuber cinereum. The infundibulum extends forward and down where it is attached to the posterior lobe of the pituitary gland.
It houses the nuclei:
- tuberal nucleus
- tuberomamillary nucleus [1]
Tuberomamillary nucleus[]
- Main article: Tuberomamillary nucleus
The tuberomammillary nucleus (TMN) is the sole source of histamine in the brain. [2]
Function[]
Circadian rhythm[]
- Main article: Histamine H1_receptor#Neurophysiology
By its release of histamine, the tuberomamillary nucleus of the tuber cinereum helps to regulate the circadian cycle.
