Serotonin/5-HT (5-hydroxytryptamine) is a neurotransmitters present in the brain. Anti-Serotonin specifically stains enterochromaffin cells in formalin-fixed, paraffin-embedded sections of normal human appendix and serotonin-containing carcinoid tumors. In the central nervous system (CNS), the antiserum reacts with serotonin-containing fibers in perfusion-fixed, free-floating sections of rat brain.
Serotonin/5-HT, the midbrain raphe system controls mood, emotion, cognition and motor functions, circadian and neuroendocrine rhythms, like food intake, sleep and reproductive activity. It participates in natural reward-related physiology and behaviour, from feeding to sexual activity.
