Data (irregular spiking time-series) obtained in vivo from singular neurons belonging to brain's Red Nucleus are analyzed using multifractal tools and long-range correlations possessing scaling properties are found. A broad probability distribution (log-normal–like) is identified for generalized interspike intervals using the multifractal tools. A possibility of excessive utilization of stochastic resonance mechanism by genetically defined depressive brains has been briefly discussed in the light of the experimental results.
