Who directs us? The neurochemistry of
to Drink or not to drink - here in what a question! And the neurochemistry - the section of biochemistry studying chemical and cellular mechanisms of activity of nervous system is urged to answer it.
The neurochemistry is subdivided: on the general , studying chemical properties of nervous system out of connection with concrete physiological activity, and functional (private), studying chemical and molecular mechanisms of activity of nervous system in the course of realization of this or that physiological function.
Functional neurochemistry - the section of neurochemistry studying the chemical processes proceeding when functioning nervous system. The knowledge of chemical mechanisms of activity of a brain is not only a problem of biology, but matters in aspiration of the person to understanding of as persons, to understanding of the place and a role on Earth. The nervous system represents biological structure which main functions consist in the direct or mediated management of the most important functions of an organism, and also in the regulatory and integrating role in relation to the processes proceeding in a complete human body or an animal. Therefore neurochemistry - one of the most difficult, the modern and violently developing field of biochemistry and a neurobiology. It is closely connected with such directions of biology as morphology and physiology of nervous system, molecular biology and genetics, and also with a number of clinical disciplines, in particular - with neuropathology and psychiatry .
Two superproblems lie in the field of neurochemistry.
One of them, is told, primordially Russian: “To drink or not to drink?“. And if to drink, then how many, if one - have not enough, two - there is a lot of, and three - just right . Alcoholism is generated by purely chemical dependence to which, in principle, 15% of the population are subject. This assessment is similar to the number of alcoholics in Russia. Do not drink much, as a rule, those to whom from alcohol badly. It causes structural changes in an organism. At long alcohol intake fabrics regenerate and their atrophy is observed that especially is considerably shown in a brain. At first there is an atrophy of big hemispheres and a cerebellum, stretching and desolation of their bark in connection with death of cortical neurons. Change of structure of a brain arises already at “moderate“ consumption of alcohol. After four years of consumption of alcohol the wrinkled brain from - for death of billions of cortical cages takes place .
Drug addiction is a world problem. In Russia rapid growth of number of heroin addicts continues, there is “rejuvenation“ of an illness. Soon the problem can get, except medical, also socially - political coloring as it infringes on interests and safety of Russia more and more.
Neurochemistry of emotions - also big section of this science. A depression and aggression, love and indifference - substantially external manifestations of chemical activity of a brain. In a word, gipotalamus igitur !
The Novosibirsk institute of neurochemistry of aggressive states, scientific research institute of neurology of the Russian Academy of Medical Science work (a lab. neurochemistry, Moscow), Institute of physiologically active agents of the Russian Academy of Sciences (lab. neurochemistry, Chernogolovk). There is a Neyrokhimiya magazine. It is possible to esteem: Dmitriyev V. K., Critical researches about consumption of alcohol in Russia. M.: 2001; Hukho F., Neurochemistry.
