This finding may seem surprising given that less than one in a million CNS neurons produce serotonin and the vast majority of total body serotonin is found outside the CNS . However, brainstem serotonin neurons send ascending projections that terminate in a defined and organized manner in cortical, limbic, midbrain, and hindbrain regions ( Figure 1 ).
