PG - 21-4 AB - The expression of neuronal nitric oxide synthase (nNOS) in the trigeminal ganglia (TG) of the infrared-sensitive crotaline snake Trimeresurus flavoviridis was studied immunohistochemically. The percentage of nNOS-positive (+) neurons in the TG was significantly higher (about 3.5-fold, P<0.001) in the mandibular division than in the infrared-sensory processing area (the maxillary division and ophthalmic ganglion). nNOS was found in varying sizes of TG neurons. However, nNOS (+) neurons were more abundant in small and large neurons than in medium-sized neurons, which include most of the infrared-sensitive neurons of the TG. These findings suggest that nNOS may be involved in normal physiological functions, such as the transmission of tactile, vibrotactile, and nociceptive sensations in the TG, rather than in infrared sensory processing in this species.
