Where is trapezoid body

Authors Authors and affiliations John E. How to cite. Definition The trapezoid body is an internal transverse pathway in the caudal pons, just dorsal to the pontine nuclei and ventral to the medial lemnisci, carrying decussating auditory fibers from the ventral cochlear nuclei on one side of the brainstem to the superior olivary nuclei on the other.

Description The trapezoid body is part of the auditory pathway where some of the axons coming from the cochlear nucleus decussate, or cross over to the other side before traveling on to the superior olivary nucleus.

Furthermore, the MNTB has been positively identified in all mammals examined, ranging from opossum and mice to chimpanzees. From the early s through , a number of studies denied the existence of the MNTB in humans and consequentially, the existence of this nucleus in the human brain has been debated for nearly 50 years. The absence of the MNTB from the human brain would negate current principles of sound localization and would require a number of novel adaptations, entirely unique to humans.
