Probabilistic and multifractal properties of spiking time-series obtained in vivo from singular neurons belonging to red nucleus of the rat brain are analyzed. Lognormal and "-1" power-law probability distributions of interspike intervals are observed for healthy and for genetically depressive rats, respectively. A simple thermodynamic model is elaborated to interpret obtained results. Investigation of long-range interspike correlations (both probabilistic and multifractal) gives indications that the genetically defined depression is related to individual neurons kinetic problems rather than to the brain system disorder.
