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.
A 2017 study found that strength and endurance training in people with Parkinson's disease had positive effects lasting for several weeks. [130] A 2023 Cochrane review on the effects of physical exercise in people with Parkinson's disease indicated that aquatic exercise might reduce severity of motor symptoms and improve quality of life.

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
“Exercise leads to increased blood flow and stimulation of neurotransmitters thought to contribute to improvements in cognitive function,” Bloomberg says. ... doing more moderate or vigorous ...
The happiness set point idea is that most people return to an average level of happiness – or a set point – after temporary highs and lows in emotionality. People whose set points lean toward positive emotionality tend to be cheerful most of the time and those whose set points tend to be more negative emotionality tend to gravitate toward ...
South African neuroscientists presented evidence that there was a physiological link on a continuum between pain and pleasure in 1980. First, the neuroscientists, Mark Gillman and Fred Lichtigfeld demonstrated that there were two endogenous endorphin systems, one pain producing and the other pain relieving.
According to Cloninger, the norepinephrine neurotransmitter has its major ascending pathways arising in the locus coeruleus in the pons, projecting onward to the hypothalamic and limbic structures, and then branching upwards to the neocortex. [16] Reward dependence has been linked to "dissociable connectivity streams" in the brain.
