The past twenty-five years have seen a strong increase in the number of publications related
to criticality in different areas of neuroscience. The potential of criticality to explain various …

Objective No current model of consciousness is univocally accepted on either theoretical or
empirical grounds, and the need for a solid unifying framework is evident. Special attention …

This is an introduction to the special issue titled" Collective behavior and evolutionary
games" that is in the making at Chaos, Solitons & Fractals. The term collective behavior …

Autapse is introduced as a self-feedback connection that connects the dendrites and axons
of the same neuron. Previous studies have revealed that the existence of the autapse can …

The healthy conscious brain is thought to operate near a critical state, reflecting optimal
information processing and high susceptibility to external stimuli. Conversely, deviations …

During non-REM sleep the largest EEG response evoked by sensory stimulation is the K-
complex (eKC), composed of an initial positive bump (P200) followed by a bistable cortical …

Experimental work, both in vitro and in vivo, reveals the occurrence of neural avalanches
with an inverse power law distribution in size and time duration. These properties are …

Criticality reportedly describes brain dynamics. The main critical feature is the presence of
scale-free neural avalanches, whose auto-organization is determined by a critical branching …

Sleep plays a key role in preserving brain function, keeping brain networks in a state that
ensures optimal computation. Empirical evidence indicates that this state is consistent with …

The stochastic solution with Gaussian stationary increments is established for the symmetric
space-time fractional diffusion equation when 0< β< α≤ 2, where 0< β≤ 1 and 0< α≤ 2 are …
