Abstract: Brain dynamics is an interdisciplinary area dealing with the processes of brain activity in at the different scales of time and space. Statistical approach provides the natural way to classify these processes according to three levels: microscopic level (single neurons), mesoscopic level (neuron clusters), and macroscopic level (the whole brain). At the microscopic level we compare classical models, representing neurons as the elements of an electrical circuit, with quantum behavior, coming from the details of biochemical pro-cesses and inter-neuron interactions. At the mesoscopic level of neuron clusters, brain may be described as a condensed matter object, in which collective perturbations (so-called quasi-particles) appear. They define the mechanisms of the information treating, including the reaction for external signals.
