| Outline of Final Research Achievements |
A study using common marmoset was conducted to understand evolution of neural mechanisms for mammalian parental behavior. First, basic behavioral data (infant retrieving test etc.) was acquired to establish methods for quantifying parental behavior of marmosets. Next, functional analysis of the medial preoptic area, which is important for expression of parental behavior in rodents, was conducted. Increased expression of c-fos mRNA was suggested after retrieving and carrying an infant. Additionally, excitotoxic lesions of the medial preoptic area suggested to decrease carrying behavior. In future it is necessary to obtain more samples and precise surgery.
