telodiencephalic fissure (tdf) The term
telodiencephalic fissure (tdf) refers to the part of the
transverse cerebral fissure (tcf) that separates the
ventral surfaces of the
corpus callosum (cc) and
fornix (fx) from the
dorsal surface of the
interbrain (IBR). Formed by the folding back of the
endbrain (EBR) over the IBR during fetal development. It is technically outside the
brain . It gets its name from the Telencephalon and Diencephalon, embryonic precursors of the EBR and IBR respectively. It together with the
cerebrocerebellar fissure (ccbf) constitute the
transverse cerebral fissure (tcf). It is found in the
human (
Riley-1943 ),
macaque (
Martin-2000 )
rat and
mouse (
NeuroNames ). Final 11 Dec 2025).
Also known as: telodiencephalic fissure, Fissura telo-diencephalica, telo-diencephalic fissure

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.
