| Popis: |
Studies on the functional role of criticality in the brain have thus far mainly examined the role of neural dynamics on stimulus encoding, with scant attention devoted to the impact of these dynamics on downstream decoding. Here, we consider the question of how a linear decoder may classify spontaneous cortical activity both near and away from a critical state. We show that accurate performance of the decoder is obtained only when network activity is near criticality. Simulations of a branching process capture these results and argue for a potential role of the critical state in providing a format for neural activity that can be adequately processed by downstream brain structures. |
