This talk will describe the scientific and technical basis for the development and use of databases in QEEG and in neurofeedback.  The principles involved in selecting subjects for inclusion, and exclusion criteria will be enumerated and discussed.  The mathematical and statistical methods used to create references will be described, including how various power and connectivity measures are computed and interpreted.  The currently available and published databases will be compared using statistical methods that show that while there is substantial agreement among the most-used databases each database may have its own strengths and weaknesses.  The use of databases in assessment and in live neurofeedback will be shown.

Learning Objectives – Intermediate; participants will be able to;

  • Describe how a QEEG database can be constructed, including selection of subjects
  • Explain how the metrics used in a QEEG database such as power and connectivity, reflect relevant brain function
  • Describe how a QEEG assessment can be correlated with clinical signs in a functional model
  • Describe how a database can be used in a neurofeedback protocol using live z-scores
