1 Summary and conclusions 1. We investigate the conditions under which cortical activity alone makes spontaneous activity self-reproducing and stable against uctuations of spike rates. Invoking simple assumptions about properties of integrate-and-re neurons it is shown that the stochastic background activity, of 1-5 spikes/second, cannot be stabilized when all neurons are excitatory. 2. On the other hand, spontaneous activity becomes self-stabilizing in presence of local inhibition: given… CONTINUE READING
