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.
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:
The tuberomammillary nucleus (TMN) is the sole source of histamine in the brain.
By its release of histamine, the tuberomammillary nucleus of the tuber cinereum helps to regulate the circadian cycle.
Mesal aspect of a brain sectioned in the median sagittal plane.
