Key findings

  • Scientometric review covering 278 peer-reviewed papers
  • Background EEG and evoked responses interact rather than being signal plus noise
  • Moved event-related analysis into the frequency and time-frequency domains
  • Brought physics of dynamical systems into brain research

A tribute review of the work of Erol Başar, a pioneer of brain-oscillation research, built on an analysis of his 278 peer-reviewed papers, his citations and his network of collaborators. It describes how he challenged the older view that evoked responses sit on top of meaningless background EEG noise, showing instead that the two interact and that event-related activity should be studied in frequency and time-frequency terms as well as over time. The authors credit him with helping shift neurophysiology toward treating the brain as a nonlinear dynamical system.
