Multifractality in critical neural field dynamics

The brain criticality framework has largely considered brain dynamics to be monofractal even though experimental evidence suggests that the brain exhibits significant multifractality.

Summary:The brain criticality framework has largely considered brain dynamics to be monofractal even though experimental evidence suggests that the brain exhibits significant multifractality. To understand how multifractality may emerge in critical-like systems, we use a computational model for critical neural oscillations. We find that multifractality emerges near a synchronization phase transition. These findings show multifractality in temporal dynamics peaks at criticality in neural fields, providing a generative model for interpreting multifractality in brain recordings.
