Brain activity spectra mature during development, reflecting changes in neural network dynamics. This study models electroencephalogram (EEG) spectral maturation using a whole-brain model, revealing key neurobiological adaptations.

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Developmental Neuroscience

Background:

  • Macroscopic neural activity spectra change significantly during development.
  • The relationship between spectral maturation and underlying brain network formation is not well understood.

Purpose of the Study:

  • To investigate the developmental maturation of electroencephalogram (EEG) spectra.
  • To link spectral changes to brain network formation and dynamics using a computational model.

Main Methods:

  • Bayesian model inversion of the spectral graph model (SGM).
  • SGM is a whole-brain model of spatiospectral neural activity coupled by the structural connectome.
  • Simulation-based inference estimated age-varying SGM parameter posterior distributions from developmental EEG spectra.

Main Results:

  • The model accurately captured observed EEG spectral maturation across development.
  • Neurobiologically consistent progression of key neural parameters was identified: long-range coupling, axonal conduction speed, and excitatory:inhibitory balance.
  • These parameters showed age-dependent changes supporting spectral maturation.

Conclusions:

  • Developmental EEG spectral maturation is driven by functional adaptations in localized neural dynamics.
  • Age-dependent changes in long-range coupling across the structural network also contribute.
  • The study provides a neurobiologically grounded explanation for developmental spectral changes in brain activity.
