PMID-19564605[0] Cognitive fitness of cost-efficient brain functional networks.

  • Idea: smaller, tighter networks are correlated with better task performance
    • working memory task in normal subjects and schizophrenics.
  • Larger networks operate with higher beta frequencies (more effort?) and show less efficient task performance.
  • Not sure about the noisy data, but v. interesting theory!
