Lready expected mainly because each brain dynamical regime is transient (Rabinovich and Varona, 2012). Duration from the transient is dependent upon the network architecture (hierarchical level, mixture of excitatory-inhibitory neurons) as well as the synaptic parameters. A direct possibility to prolong the lifetime with the SSA without having escalating the synaptic strengths is to boost the amount of neurons, because the escape time of transient chaotic trajectories grows exponentially with the dimension of your method (Crutchfield and Kaneko, 1988; Kumar et al., 2008; El Boustani and Destexhe, 2009; Lai and T , 2011). We observed this impact when proceeding from 29 to 210 neurons; our preliminary outcomes with larger networks confirm this conjecture.ACKNOWLEDGMENTOur research was supported by the IRTG 1740TRP 2011501510, funded by the DFGFAPESP.Astrocytes have traditionally been regarded as glial cells responsible for the homeostasis and metabolic assistance for neurons (Carmignoto and G ez-Gonzalo, 2010).
