[8p-N102-5] Critical neurocomputation with spontaneous activity

brain,plasticity

The brain exhibits spontaneous activity even during complete rest. Based on the critical brain hypothesis, we propose that spontaneous activity helps the brain reach and maintain a critical state, i.e., a critical point of phase transition between ordered (inactive) and chaotic (overactive) states, to achieve computational efficiency. Here, we tested in spiking neural network and dissociate neuronal culture whether and how the criticality and excitatory/inhibitory balance are stabilized by appropriate noise levels and spike-timing-dependent plasticity (STDP) windows.
