The international team of researchers discovered the unexpected role of Dofamin, a neuroploric, which is traditionally related to motivation and pleasure. Scientists have found that Dofamin is involved in reducing the value of the prizes, helps to adjust the past experience and affect future behavior. The work was published in Communications Biology.
It was previously assumed that Dofamin operates through the wrong mechanism of the award forecast. It regulates expectations if a real reward does not match the expected. However, the new study showed that his functions are much more complicated. Dopamine not only gives a reward signal, but also affects how we remember and appreciate the experience of the past.
"The dopamine function has always captured me. It plays a key role in teaching and motivation, and its dysfunction is connected with many mental disorders. "Understanding how Dofamine works, it can have a wide range of consequences," said Alex Johnson, a leading research author from Michigan University.
During the experiment, scientists trained the mice to connect the sound signal to sweet food. However, instead of food, mice was given light deficiency, which caused a unpleasant feeling. Although they did not eat at that moment, their brain connected the sound with the sweet taste.
After recovering, the mice began to understand the sweet food, as if it was ill. This shows that the change in memory itself has affected their preferences.
Using the brain activity, the technique, scientists found that the documents were played an important role in this process. When the scientists were artificially activated, the dislike for sweets increased, but when cell activity was blocked, the influence disappeared.
Researchers believe that this mechanism can be useful for addictions and mental disorders. If Dofamin can "attribute" reward memories, it can be used to reduce harmful habits such as compulsive supernate or drug addiction.
Although attempts have been conducted on mice, scientists hope that further research will approve such mechanisms in humans. If so, the discovery can lead to new treatments, to weaken the impact of destructive memories and to reassess the familiar irritants.
