lamina terminalis - BrainInfo

lamina terminalis (lter)

The term lamina terminalis (lter) refers to a thin relatively acellular membrane that forms the anterior wall of the third ventricle (3v) between the anterior commissure (ac) and interventricular foramen (ivf) dorsally and the optic chiasm (ox) ventrally. Observed by dissection it is attached to the most anterior of the circumventricular organs (CVO).( Wikipedia-2024a). Updated 17 Aug 2024.

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
