Complex brain networks share organizational principles with other systems. Network analysis reveals how brain structure and function support cognition and flexible mental states.

Area of Science:

  • Neuroscience
  • Network Science
  • Systems Biology

Background:

  • Complex networks in nature, society, and technology exhibit shared organizational principles.
  • Understanding these principles is crucial for deciphering brain organization and function.

Purpose of the Study:

  • To review general principles of complex network organization applied to brain networks.
  • To examine the structural and functional properties of large-scale brain networks.
  • To explore the relationship between neuroanatomy and cognitive processes.

Main Methods:

  • Review of existing research on complex network theory.
  • Analysis of structural properties of anatomical and functional brain networks.
  • Examination of network growth and rewiring mechanisms.

Related Experiment Videos

  • Investigation of the link between structural and dynamic connectivity patterns.

    • Main Results:

    • Brain networks, like other complex systems, adhere to general organizational principles.
    • Structural properties of brain networks can be explained by growth and rewiring processes.
    • Neuroanatomy provides the substrate for dynamic functional and effective connectivity.
    • Network analysis offers insights into integrative brain function.

    Conclusions:

    • Network science provides a powerful framework for understanding brain organization.
    • The interplay between structural and functional connectivity is key to cognition.
    • Network analysis illuminates the neural basis of flexible and coherent cognitive states.
