septum - BrainInfo

septum (SPT)

The term septum (SPT) refers to a midline structure that separates the lateral ventricles (VNL) in the forebrain (FBR) of the human ( Carpenter, 1983 ), macaque ( Paxinos-2009a ), rat ( Swanson-2004 ) and mouse ( Hof-2000 ). In the human it consists of two parts, the septum pellucidum (spl) and the septal complex (SPX) ( Wikipedia ). The other species lack an spl.

Also known as: septum, Septum, Septum telencephali, Septum pellucidum (BNA,PNA), Massa praecommissuralis, SPT

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.
