It became known how and why the brain releases dopamine

Dopamine is one of the neurotransmitters produced by endocrine cells in the brain. Any moments

bringing joy to a person, — deliciousfood, pleasant smells, communication with a pet, long-awaited rest are accompanied by the release of this biologically active substance into the blood.

Also, the death of dopamine neurons is one of the causes of the development of Parkinson's disease, so scientists are carefully studying this substance. 

The authors of a new study decided to find out howdopamine is released in the body and for what reasons. experts conducted an experiment - they injected Botox, a toxin that prevents neurons from sending chemical signals, into some brain cells of mice. During the experiments, experts observed whether the cells continued to produce the hormone.

It turned out that the “paralyzed” cells stoppedhormone production, despite the fact that they continued to receive signals from «healthy» neighboring cells. From this, researchers conclude that the process of dopamine production is self-regulating.

Next, scientists plan to study the connection between the activity of dopamine neurons with some other factors - the same release of calcium.
