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).
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.
Some smells release neurotransmitters in the brain. Think: serotonin, dopamine, and endorphins. These brain chemicals can lead to feelings of happiness and relaxation.
SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic neuron, in a process known as serotonin reuptake. [ 6 ] This transport of serotonin by the SERT protein terminates the action of serotonin and recycles it in a sodium-dependent manner.
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.
“Exercise leads to increased blood flow and stimulation of neurotransmitters thought to contribute to improvements in cognitive function,” Bloomberg says. ... which is linked to cognitive ...
