摘要
The induction of c-fos in the suprachiasmatic nucleus (SCN) by the 5-HT2A/2C agonist, DOI was studied at mid-dark in neonatal rats. The number of cells expressing c-FOS immunoreactivity following DOI was low 3 days after birth, but increased rapidly over the next 3 days. By contrast, light exposure stimulated cells throughout this period. These results are consistent with the arrival of serotonergic afferents at the SCN and their role in the entrainment of rhythms.
