Department of Biology , Hainan Normal University , Haikou College of Life Science , Beijing Normal University , Beijing Abstract : Using the neural tracer biotinylated dextran amine and the immunohistochemical methods , we found that
high vocal center ( HVc) in Emberiza elegans received projections from the auditory area2field (L) , nucleus interfacialis of midneostriatum , magnocellular nucleus of the anterior neostriatum (MAN) , nucleus uvaeformis , and locus ceruleus ofpons ; HVc projected to the robust archistriatum (RA) and area X of lobus (X) . HVc shell projected to the RA cup and received from L . As there were many neural connections among the vocal control and learning pathway , and the auditorycenter , vocal learning may depend on a feedback of listening senses. Substance P (SP) labeled neurons distributed in HVc , RA and MAN. SP labeled fibers and terminals distributed in X , the nucleus dorsalis medialis , the nucleus hy2 poglossi , pars tracheosyringealis , the nucleus ovoidalis shell , the shell of mesencephalicus lateralis , pars dorsalis , and the nucleus intercollicularis. SP widely distributed in vocal2auditory centers , and may involve in their activities.
Key words : Emberiza elegans ; Vocal nucleus ; Auditory center ; Nervons projection ; Substance P
