Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
This feel-good hormone plays a key role in everything from sleep and digestion to happiness and contentment—here's how to keep it flowin'. 5 Natural Ways to Boost Serotonin and Start Feeling Happier
Happiness is primarily controlled by the levels of dopamine and serotonin in the body. Both are monoamine neurotransmitters that act on different sites in the body. Serotonin acts on receptors in the gastrointestinal tract while dopamine acts on receptors in the brain, while both performing similar functions. [16]
"Dopamine is associated with a sense of reward, pleasant sensations and motivation, and serotonin is associated with happiness, decreased depression and anxiety, and learning and motivation ...
An increase in dopamine release also influences the mesocorticolimbic system through the VTA cells, increasing mood and open mindedness in older adults. Positive affect also stimulates dopamine production in the prefrontal cortex and the anterior cingulate facilities, which help with processing working memory and executive attention.
The combination of dopamine, serotonin and oxytocin is already pretty dreamy, but the brain takes that natural high to the next level when you reach the big O by releasing endogenous (i.e., made ...
Norepinephrine (NE), apart from producing alertness and arousal, is seen as influencing the brain reward system [14] by aiding in the learning of new paired associations. [ 15 ] According to Cloninger, the norepinephrine neurotransmitter has its major ascending pathways arising in the locus coeruleus in the pons , projecting onward to the ...
