Addiction (Cake, Drugs, and Rock&Roll) – Bite Sci-zed

Did you know we can be addicted to music? Some are surprised to learn it, others less Last year, researchers at McGill University published the article: Anatomically distinct dopamine secretion During the wait, then the experience of emotional peaks due to music Researchers have selected people who feel chills while listening to certain songs

Then measured their temperature, pulse and breathing rate To check if these shivers were the result of a strong emotion And they could verify that it was an emotional response Participants' brains were observed on the MRI as they listened to these pieces The researchers found the same secretions of dopamine

(the pleasure hormone) In the same way as a person addicted to cocaine when taking a dose That's crazy ! It means that the brain rewards the same way, A person listening to a stimulating piece of music, An addict who injects cocaine According to the theory of evolution, we can think that the better we feel, The more likely we are to do something right so we need to encourage that action The brain is rewarding us that way; that's not the case for drugs

The drug exploits the reward mechanism to push for the consumption of a product yet dangerous for the body But obviously this mechanism can be used for good things That's why we like the "junk food" If you were a caveman chasing the mammoth, It was crucial that eating the meat of the animal was a pleasant experience, To push you to go hunting again Our body learns to appreciate fat, like butter, Because it was something impossible to obtain by picking For that, you really had to fight

But nowadays, just go to the grocery store for butter, this hormonal reward is more dangerous than healthy Research has been conducted to find out whether obesity can be likened to a food addiction What they discovered is interesting: The researchers discovered that the hormonal reward for food followed a Goldilocks principle They showed girls an image of a piece of cake, By asking them to imagine eating this cake, what would be his taste They performed MRIs while the girls thought about it They found a bimodal distribution: On one side of the curve, the girls who found the image of the cake Strongly activated hormonal reward mechanism These girls have a higher risk of eating excessively, and becoming obese On the other hand, those for which the reaction was not strong enough, could also have this tendency If one piece of cake does not satisfy you enough, then you will probably take two or three to make up for it This is the principle of Goldilocks: Answer too strong, you eat too much, answer too weak, you eat too much

But with the correct dose of dopamine, you will feel good without having to abuse Researchers have highlighted genetic links between overeating and obesity But, I like this concept of reward for action If this reward is too strong, it will be done too often, But if it's too weak, you'll do it too! This is also one of the reasons that drug addicts overdose After a while, the brain is less sensitive to the dose taken, So you have to constantly increase the dose to keep the same effect It happens a moment, the dose is fatal Another area where this type of risk taking can lead to a dangerous addiction: gambling

Another study shows that players who wait for roulette to spin, dreaming of a victory, Have the same type of anticipated reward as drug addicts waiting for their dose Dopamine makes you feel good when you get what you want, But it is also she who provokes this desire, and rewards in advance That begs the question: what is addiction? If we have the same reaction to food or cash games as an addict for his dose, So are we dependent? Is it bad? Should we be afraid of an addiction to music? What? We are moving forward, we are doing science!
