Biological Foundations
  • Myelinization as the cause of transmission speed and efficiency
  • Brain volume (total, white & grey matter volume, cortical thickness, corpus callosum, specific brain areas)
    • Gignac, G. E., & Bates, T. C. (2017). Brain volume and intelligence: The moderating role of intelligence measurement quality. Intelligence, 64, 18-29. doi:10.1016/j.intell.2017.06.004
  • White matter integrity (Penke)
  • Post synaptic density (Hill)
  • Fronto-Parietal Integration Theory (Jung & Haier)
  • Electrical (magnetic) activity on the scull
    • Power in different frequency bands
    • Event-related potentials as markers of speed and information processing (P300, MMN, N100 etc)
