Serotonin (5-HT), norepinephrine (NE) and 5-hydroxyindoleacetic acid (HIAA) levels were measured during ontogeny of frontoparietal cortex in Balb/C mice by high-pressure liquid chromatography (HPLC) with electrochemical detection. Unlike NE, the concentration of 5-HT was transiently elevated to more than twice the adult level during the first postnatal week; this was accompanied by increased HIAA content comparable to the adult, indicating elevated levels of 5-HT release. Since a transient hyperplasia of 5-HT-immunoreactive fibers and uptake sites has been observed previously in the same cortical areas, the transient elevation of 5-HT levels may play an important role in shaping early postnatal morphogenetic events in neocortex.
