Abstract:
Objective To observe the distribution of substance P in the accessory auditory pathway of pigeon. Methods Immunocytochemical staining by using specific antibody against substance P was used. Results Intensely stained SP-like immunoreactive (SP-ir) neurons and fibers were mainly observed in the nucleus intercollicularis (ICo), periphery area of nucleus ventralis leminisci lateralis(VLV), shell area of nucleus ovoidalis (Ov), nucleus periventricularis magnocellularis (PVM), nucleus ventromedialis hypothalami(VMN), periphery area of the nucleus taeniae (Tn) of posterior archistriatum, nucleus preopticus anterior(POA), and the tractus septomesencephalicus(TSM).Conclusion There are many SP-ir structures in the accessory auditory pathway and brain regions related to reproductive control of the pigeon. Our results suggest SP may play a functional role in the vocal and endocrine regulation.
