Hippocampal dentate granule cells morphology

The effect of serotonin on synaptogenesis is not limited to the sensory cortex, as it has also been reported that reduction of serotonin in the early postnatal period can result in changes in the morphology of hippocampal dentate granule cells, particularly at the level of the synapse, as reflected by the permanent reduction in synaptic spine density [80].
