The Measurement of Synchronization

  • J. C. Shaw
  • C. Ongley


The high degree of spatial organization in the cortex makes it reasonable to look for a relationship between cortical function and the EEG in terms of the spatial distribution or topography of electrical activity. Although this is implicit in almost all EEG research, it is seldom stated explicitly. Synchronous activity is so named because of its specific topographic characteristics and its measurement may be useful to help understand the relationships between the obvious EEG phenomenon and the underlying physiological process.
