Victoria: A lot of people have heard about dopamine and serotonin. Even at the appointments, I hear from my clients about it.

Vyacheslav: People get more educated.

Victoria: That's great, but I have an impression that they imagine a soup in the brain where all these neurotransmitters: dopamine, serotonin and glutamate are swimming. Where are these neurotransmitters located? How does it look like?

Vyacheslav: Our brain is not a soup. It's rather a planet that is inhabited with nerve cells-neurons. They were calculated, and its number is 90 milliards. It's more than people living on the Earth. Each neuron have connections with 3,4, 5 thousand neurons and neurotransmitters are located in these connections. If you multiply 90 milliards by 5 thousand, you will get trillions of synaptic connections. In each connection one neurotransmitter is functioning. However, some supporting neurotransmitters can also be released. We find dopamine and serotonin in cerebral cortex, basal ganglia and in hypothalamus. It's not a soup, it's complex organized information carriers that send strong determined signals in strong determined situations. From time to time, they have to do with total generalization. They support the wakefulness level and filter the information. In other words, there are neural networks that have specialized functions.Programmers have been trying to create networks. They have found out that one network, that consists of 5 thousand neurons, is able to calculate and memorize a lot of information. And we have not 5 thousand, not 5 million and even not 5 milliard neurons. Our networks are extremely complex, interesting and plastic as well. As certain synaptic contacts are being used, synapses start to change its characteristics. Some signals get stronger, some get weaker. The adaption is always going on. The main task of our brains is to reflect the environment. The reflection of the world is created in our brain. This reflection is created by certain neurotransmitters that have their own functions. These functions are constantly changing according to your own life experience. It also depends on your genes and hormones. It's all very interesting. And as a result are created unique we. We are unique at the level of DNA and at the level of the immune system. We are also unique at the level of brain morphology, all neuronal networks and at the level of neurochemical interactions. There is definitely no place for simplicity.
