Vagotomy induced changes in acetyl cholinesterase staining and substance P-like immunoreactivity in the gustatory lobes of goldfish

摘要

In teleost fish, the visceral sensory nuclei of the medulla are clearly separated into gustatory lobes and a general visceral sensory nucleus. Those branches of the vagus nerve which innervate the orobranchial cavity terminate in the vagal gustatory lobe, while the general visceral component of the vagus nerve terminates in the separate general visceral nucleus. In goldfish, the vagal lobe is a complex, laminated structure containing both motor and sensory elements.
