[The neuronal theory and new concepts of the structure of the nervous system]

An analysis of neuron theory modern state was carried out on the base of data from literature and available material. The idea of anatomic, functional and biochemical polarity self-dependence of a neuron and its histochemical polarity have changed significantly. It is said to be confirmed that neuron does not work on its own, its trophics is impossible without glia and one neuron may contain not one but several mediators combined with modulators and regulatory neuropeptides. Postulates on the nervous system module organization seems to be the most well-grounded.
