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.

StructureEdit

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 nucleusEdit

Main article: Tuberomamillary nucleus

The tuberomammillary nucleus (TMN) is the sole source of histamine in the brain. [2]

FunctionEdit

Circadian rhythmEdit

Main article: Histamine H1_receptor#Neurophysiology

By its release of histamine, the tuberomamillary nucleus of the tuber cinereum helps to regulate the circadian cycle.
