While β-endorphin is studied for its opioid activity, α-endorphin and γ-endorphin both lack affinity for opiate receptors and thus do not affect the body in the same way that β-endorphin does. Some studies have characterized α-endorphin activity as similar to that of psychostimulants and γ-endorphin activity to that of neuroleptics ...
Laughter is a pleasant physical reaction and emotion consisting usually of rhythmical, usually audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can rise from such activities as being tickled, [1] or from humorous stories, imagery, videos or ...
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
Relief theory suggests humor is a mechanism for pent-up emotions or tension through emotional relief. In this theory, laughter serves as a homeostatic mechanism by which psychological stress is reduced [1] [3] [7] Humor may thus facilitate ease of the tension caused by one's fears, for example.
Gelotology (from the Greek γέλως gelos "laughter") [1] is the study of laughter and its effects on the body, from a psychological and physiological perspective. Its proponents often advocate induction of laughter on therapeutic grounds in alternative medicine. The field of study was pioneered by William F. Fry of Stanford University. [2]
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 ...
Brain opioid peptide systems are known to play an important role in motivation, emotion, attachment behaviour, the response to stress and pain, control of food intake, and the rewarding effects of alcohol and nicotine. Opioid-like peptides may also be absorbed from partially digested food (casomorphins, exorphins, and rubiscolins).
Alcohol consumption causes an increase in the release of β-Endorphins within the regions of the brain's reward system. Regular and long-term consumption of alcohol consequently leads to a deficit in the levels of β-Endorphins that requires continuous consumption of alcohol to replenish.
