(多巴胺) system in the brain. Therefore we thought that dopamine activation might also promote associative learning," says Prof. Sebastian Haesler, who led the study.To prove that novelty indeed activates dopamine
including memory, motor control, and focus. But perhaps most importantly, dopamine is the key player in the pleasure/reward response, a natural brain function designed to motivate and reinforce behaviors

Dopamine (DA) is a major monoamine neurotransmitter in the brain although a substantial part of the overall DA in the body is produced by mesenteric organs [1]. It engages in higher functions of the brain including spatial memory [2], motivation [3], arousal [4], reward and pleasure [5,...

in the brain. It this means that it takes more and more dopamine to create the same 25sensation, making it even more difficult to stop watching short videos.Studies have shown that too much use of social media can lead to a decrease in attention span, and short videos may be even more...
Finally, to confirm that the observed behavioral effects are specific and not caused by confounding factors that can accompany optogenetic manipulations (for example, light-induced tissue heating and paradoxical excitation of inhibitory opsins38), we performed a complementary loss-of-function experiment. ...
Such baseline-dependent effects of dopaminergic drugs have been attributed most commonly to excess dopamine D1 receptor stimulation in the prefrontal cortex, in accordance with a nonlinear, “inverted-U”-shaped relationship between dopamine and prefrontal function.

THE exact neurophysiological role of dopamine is still unclear, but it has been implicated in the functioning of the extra-pyramidal motor system (EPS)1,2. Experiments on animals and humans, however, indicate that the smooth functioning of the EPS depend
As a brain correlate of mental health, dopamine has a central functional role in behavioral regulation from healthy reward-seeking to pathological adaptation to stress in response to adversity. This narrative review offers a spotlight view of the transition from healthy reward function, under the ...
