In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
Technology use induces a dopamine response on par with any normal, enjoyable experience: roughly a 50% to 100% increase. By contrast, heroin, cocaine and amphetamine — three highly addictive drugs — can cause dopamine spikes ranging as high as 300%, [18] 350%, [19] and 1,365% [20] respectively. In addition, dopamine receptors themselves ...
Chemically they are closely related to dopamine, and there is a type of melanin, known as dopamine-melanin, that can be synthesized by oxidation of dopamine via the enzyme tyrosinase. [150] The melanin that darkens human skin is not of this type: it is synthesized by a pathway that uses L-DOPA as a precursor but not dopamine. [ 150 ]

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 ...
The dopamine hypothesis of stuttering attributes to the phenomenon of stuttering a hyperactive and disturbed dopaminergic signal transduction in the brain. The theory is derived from observations in medical neuroimaging and from the empirical response of some antipsychotics and their antagonistic effects on the dopamine receptor.
