trapazoid body
The trapezoid body
is part of the auditory pathway.
It is a bundle of fibers and cells in the tegmentum. It consists of fibers
from the ventral cochlear nucleus.
A collection of nerve cells inside
forms a trapezoid nucleus.
The Trapezoid body
is a bundle of decussating fibers
in the ventral pons
that carry information used for
binaural computations in the brainstem.
The superior olivary nucleus is situated on the dorsal surface of the trapezoid body.
Most nerve fibers pass directly from the
superior olivary nuclei to the inferior colliculus.
Axons leaving the ventral cochlear nucleus (VCN) form a broad pathway
that crosses under the brain stem
in the trapezoid body.
The intermediate acoustic stria,
also leaves the VCN, merging with
the trapezoid body close to the
superior olivary complex,
where many of its axons synapse.
Axons leaving the dorsal cochlear nucleus (DCN) form the dorsal acoustic stria,
which reaches primarily the
contralateral dorsal nucleus of the lateral lemniscus and the central nucleus of the inferior colliculus.
