The
marmoset has a well-developed visual pathway; therefore, it has been used for
studying the development of the optic chiasm. We performed high angular
resolution diffusion imaging (HARDI) with high spatial resolution of the ex
vivo optic chiasm in order to resolve the crossing pathways. We succeeded in
visualizing the precise fiber structure in the optic chiasm with
semidecussation, therefore ex vivo HARDI will be powerful tool for studying
the neuroanatomic features of the optic chiasm.
