Abstract: The dynamical model of the biological neurons net creation is suggested. The dynamics of growth of the net is described by standard heat equation with activity neurons equation. The footing of the theory is very simple – the axon growth is in the direction of the greatest media concentration which supply its growth. The media is standing out by neurons in active state. The activation takes place due to external random influences. The system of equations is solved for two dimensional as well as three dimensional cases.

Keywords: neural networks, diffusion equation, neural network's plasticity, axon growth.
