Area of Science:

Neuroscience
Complex Systems

Background:

The brain's critical dynamics are often described by self-similarity.
Experimental data indicate significant multifractality in brain activity.
A gap exists in understanding multifractality's emergence in critical systems.

Purpose of the Study:

To investigate the emergence of multifractality in neural field models near criticality.
To explore the relationship between neural oscillations, phase transitions, and multifractal dynamics.
To provide a theoretical framework for interpreting multifractality in neural recordings.

Main Methods:

Utilized a neural field model with neural oscillations.
Simulated critical phase transitions within the model.
Analyzed the emergence and variation of multifractality near these transitions.

Main Results:

Multifractality was observed to emerge near a synchronization phase transition.
The pattern of multifractality varied depending on the specific phase transition.
The findings demonstrate multifractality in temporal dynamics near criticality in neural fields.

Conclusions:

Multifractality naturally arises in neural field models at criticality.
This provides a formal basis for understanding multifractal brain dynamics.
The study bridges theoretical models and experimental observations of brain complexity.
