Topic: canonical oscillatory bands

Neuronal processing in the brain occurs rhythmically across a set of discrete frequency bands, spanning over two orders of magnitude. The origin of these rhythms remains a matter of debate, as well as why activity appears to be organized in canonical bands. Here we demonstrate that the relative distribution of frequency bands emerges from the dynamics of recurrent neural networks (RNNs) performing error correction. These networks achieve best performance when processing pulsed inputs with noise levels proportional to those observed in cortical networks. In this optimal regime, the performance
