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

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


Circadian rhythm

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