Purpose: This study was carried out to investigate the spatiotemporal localization of the amygdaloid nucleus innervating the rat stomach using PRV-BaBlu, which has been known to be an excellent type of neurotracer with the ability to transpass the neuronalsynaptic cleft. Methods: Ninety Sprague-Dawley rats (250~300 g) that were injected with PRV-BaBlu into the stomach were randomly divided into 3, 4 and 5 day groups (each group n=30). $2{\mu}l$ of PRV-BaBlu, a genetically modified strain of PRV-Bartha with the lac-Z gene,was injected into the rat stomach and immunostained with a mouse anti-${\beta}$-galactosidase at 3, 4 and 5 days after the virus injection. Results: The PRV-BaBlu infected the neurons in the amygdaloid nucleus, and the degree of viral infection in experimental animals showed a tendency to increase significantly with time (p<0.05). The neurons between the left and right amygdaloid nucleus significantly differ (p<0.05). Conclusion: This showed that PRV-BaBlu was an excellent neurotracer for localizing the amygdaloid nucleus, and the amygdaloid nucleus has a sensory input and motor output on stomach movement, influencing emotional behavior.
