In the present study, antibodies against the synthesizing enzyme for dopamine (anti-tyrosine hydroxylase, TH), noradrenalin (anti-dopamine β-hydroxylase, DBH), and adrenalin (anti-phenylethanolamine N-methyl transferase, PNMT) were used to identify the presence of catecholamine containing neurons within the guinea pig vestibular endorgans. Noradrenergic (TH, DBH-positive/PNMT-negative) fibers were found in the stroma of cristae ampullares and maculae. Ultrastructurally, immunoreactive fibers were distributed near myelinated, non-myelinated nerve fibers, and blood vessels.
