The human brain differs from that of monkeys by the large number of dopamine neurons, thanks to which we are able to experience pleasure.
This was told by Spanish, Italian and American scientists who analyzed genes active in various parts of the brain of macaques, chimpanzees and humans.
For the experiment, fragments of the brain tissue of six people were used, as well as five chimpanzees and macaques.
According to scientists, the complex system of dopamine production is quite fragile. Impaired synthesis of this substance provokes various mental disorders and autism spectrum disorders, as well as Parkinson's disease and schizophrenia.
Note that dopamine endows a person with quick wits, and also affects coordination of movements and the ability to feel pleasure. People with a high content of this substance in their blood are the only creatures on Earth capable of receiving pleasure from the results of the successful implementation of their plans.
In addition, dopamine is responsible for human phenomena such as hopes and dreams. For this reason, a person is able to make plans and for the sake of his goals is ready to experience all kinds of hardships.
