How does "dopamine", which is closely related to human motivation, work?

ByHartwig HKD

Dopamine is a neurotransmitter present in the human central nervous system and is known as a substance deeply related to emotions and motivation related to "fun". In the street "How to get dopamineAlthough they are widespread, recent experiments have revealed that there was some mistake in recognition of dopamine to date.

A magazine introducing the latest research of the neuroscience systemNeuronAtUniversitat Jaume IIn a dissertation published by a researcher, researchers are investigating whether the two ideas of "dopamine" widely spread and "the disease is related to lack of motivation and mental fatigue" are really correct .

Merce Correa, who works as a psychologist at Universitat Jaume I, said, "Dopamine controls elements such as" fun "and" rewards ", which are released in the body, such as when humans achieve something, However, when collecting the latest research data etc., this neurotransmitter called dopamine is "Before achieving the goalIt has already been released to the public that we have found that humans are promoting actions to gain something and achieve goals. In other words, dopamine is released to get some sort of good things or to avoid bad things. "

Studies have revealed that dopamine is responsive to stress, pain, loss sense, etc., besides emotion such as "fun", and it is a response to dopamine which has been emphasized as "substance with positive influence" A slightly different result from recognition was obtained, Correa said.

In the thesis, we are investigating dopamine based on data from several previous studies, and among the preceding studies research on "the role of dopamine in animal motivation", which the University of Connecticut has studied over the past 20 years also It contains. Dopamine maintains the level of human activity to achieve the goal, which in principle seems to work positive. However, it is not necessarily that a person's goal is not necessarily "wanting to be a good student", but some people think that they want to abuse drugs, so they always work as good as possible. In addition, Correa says that the idea that a lot of dopamine is released, the motivation of "do something!" Will be higher, was correct.

In neurobiology, "raising people's motivation" is considered to be important for various fields such as work, education and health. So, dopamine is thought to be a hint to clarify the cause of "disease caused by depressed vitality" like depression.

According to Correa, "People who are not energized do not want to do anything, so the amount of dopamine will decrease," and the decline and motivation of vitality is due to Parkinson's disease and other mental fatigue, It seems to be related to multiple sclerosis, connective tissue inflammation and so on.

In the past, it was thought that dopamine was released after achieving the goal or feeling satisfaction, but it was clarified in the paper that was announced this time that this idea was wrong. Because of this, Correa said, "Inhibiting the dopamine action that has been used for psychosis etc.Dopamine antagonistI have not acted as perhaps as I thought at all ".
