The power-law exponents of observed size and lifetime distributions of near-critical neural avalanches are calculated from neural field theory using diagrammatic methods. This brings neural avalanches within the ambit of neural field theory, which has also previously explained near-critical 1/f spectra and many other observed features of neural activity. This strengthens the case for near-criticality of the brain and opens the way for these other phenomena to be interrelated with avalanches and their dynamics.
运用图表方法,从神经场理论出发,计算出近临界神经爆发的观测大小和寿命分布的幂律指数。这使得神经爆发处于神经场理论的范围之内,该理论此前还解释了近临界 1/f 谱和许多其他观察到的神经活动特征。这进一步证明了大脑的近临界性,并为这些其他现象与爆发及其动力学相关联开辟了道路。
