Binding of serotonin to rat brain membranes increased linearly from birth to adulthood, but newborn receptor densities were already 39% of adult levels. These data suggest a postnatal development of serotonin receptors, coincident with synaptic maturation but do not preclude a non-transmitter function for serotonin during early maturation.
