Brain function complexity, measured by electroencephalography (EEG) dimension, increases with age after puberty. This suggests that the "wisdom of old age" may stem from more complex brain dynamics.

Area of Science:

  • Neuroscience
  • Human Physiology
  • Cognitive Aging

Background:

  • Normal aging is often associated with declines in metabolic and memory functions.
  • The accumulation of experience may involve the formation of neuronal cell assemblies.
  • The complexity of brain dynamics might underlie cognitive abilities in older adults.

Purpose of the Study:

  • To investigate age-related changes in human brain function.
  • To test the hypothesis that electroencephalography (EEG) dimension increases with age.
  • To explore the neurophysiological basis of cognitive function across the lifespan.

Main Methods:

  • Analysis of resting-state electroencephalography (EEG) data.
  • Utilized traditional EEG power spectra analysis.

  • Employed the correlational dimension to measure EEG dynamics complexity.

    • Main Results:

    • EEG dimension significantly increases with age after a notable rise during puberty.
    • A linear increase in brain dynamics complexity was observed from adolescence to older adulthood.
    • The frontal associative cortex showed the greatest increase in complexity during maturation (7-25 years).

    Conclusions:

    • The study confirms that EEG complexity increases linearly with age, supporting the hypothesis.
    • Increased brain dynamics complexity may represent the neurophysiological basis for enhanced cognitive abilities in older age.
    • Maturation of the frontal associative cortex plays a key role in the development of brain complexity during early adulthood.
