CRITICALITY IN A SIMPLE-MODEL FOR BRAIN FUNCTIONING

We introduce a simple model for a set of interacting idealized neurons . The model presents a self-organized state in which avalanches of all sizes are observed and activity is detected in the whole extension of the simulated system without a typical length scale. The basic elemen ts of the model are endowed with the main features of a neuron functio n. On this basis it is speculated that the collective system that they form, i.e., the brain, could display self-organized criticality in so me situations. (C) 1998 Elsevier Science B.V.
