"A self-organising model is proposed to explain the criticality\nin cortical networks deduced from recent observations of neuronal\navalanches. Prevailing understanding of self-organised criticality (SOC)\ndictates that conservation of energy is essential to its emergence.\nNeuronal networks however are inherently non-conservative as demonstrated\nby microelectrode recordings. The model presented here shows that SOC can\narise in non-conservative systems as well, if driven internally. Evidence\nsuggests that synaptic background activity provides the internal drive for non-conservative\ncortical networks to achieve and maintain a critical state. SOC is robust to\nany degree $\\eta \\in (0,1]$ of background activity when the network size $N$ \nis large enough such that $\\eta N\\sim 10^3$. For small networks, a strong background \nleads to epileptiform activity, consistent with neurophysiological knowledge\nabout epilepsy."^^ . "2007-01" . . . . . . . "D.E."^^ . "Juanico"^^ . "D.E.
