Aberrant expression of the presynaptic serotonin 1A receptor (5-HT1A-R) because of a polymorphism in the 5-HT1A-R gene is associated with severe depression in human, whereas its absence up to postnatal day 21 (P21) in the forebrain of mice results in heightened anxiety in adulthood. These observations collectively indicate that the 5-HT1A-R has a crucial role in brain development. To understand the mechanistic underpinnings of this phenomenon, we used organotypic slice cultures of hippocampi from C57BL6 mice (C57) at P15, which coincides with the peak of neonatal synaptogenesis. Stimulation of the hippocampal 5-HT1A-R caused a dramatic increase …
