| Outline of Final Research Achievements |
Visual imprinting in chicks could be facilitated by the presence of another chick at the right side. Medial and cortical divisions of amygdala were suggested to regulate the expression of social emotion in imprinting. One of the natriuretic peptides was expressed in these regions. Its expression in the brain was enhanced during the critical period as well as after the imprinting training. Moreover, injection of this peptide facilitated imprinting. We expect that these results can lead to elucidate the mechanism by which development of social behavior is regulated in juveniles.
