Serotonin is produced primarily in which brain structure?

Explanation:
Serotonin is produced by neurons whose cell bodies reside in the raphe nuclei of the brainstem, especially the dorsal and median raphe. These serotonergic neurons project widely to the cortex, limbic system, and other areas to help regulate mood, sleep, and arousal. The locus coeruleus is the main source of norepinephrine, not serotonin. The substantia nigra contains dopaminergic neurons tied to movement and reward, while the hippocampus is a target of serotonergic input rather than the primary production site. So, the raphe nuclei are the primary source of serotonin.
