Where is serotonin released?
During neurotransmission, when the serotonin is released into the synaptic cleft , the serotonin can either be transported to receptors on the postsynaptic neuron, being destroyed by enzymes, or being reabsorbed back into the presynaptic neuron which released the chemical.
