A sexually dimorphic vasopressin innervation of auditory pathways in the guinea pig brain.
Vasopressin-like immunoreactivity was detected in the auditory brainstem of female guinea pigs. Stained cell bodies and fibres were found in the inferior colliculus and in the ventral trapezoid body, and immunoreactive fibres in the dorsal cochlear nucleus. No vasopressin immunoreactivity was detected in the auditory brainstem of male guinea pigs. Using oxytocin antisera we found neither immunoreactive perikarya nor fibres in the auditory pathways of guinea pigs of both sexes.
