Tom Collura Technical Foundations of Neurofeedback

This workshop will describe the technical foundations of the practice of neurofeedback, including the neurophysiological, electronic, and computer aspects. A signal is traced from its origin in the brain, through the instrumentation, until a visual or auditory feedback signal is presented to the trainee. Principles to be covered include amplifier characteristics, digitization, filtering, graphics and sound, and feedback algorithms. Technical data in the form of digital traces, timing measurements, and statistical summaries, will be presented and discussed. Material covered will not be specific to any particular instrument, and will pertain to all types of equipment.

Each participant will have the opportunity to articulate the technical foundations of EEG neurofeedback, including neurophysiology, electronics, signal processing, and user-interfacing. Understand specifications such as bandwidth, accuracy, and response time, in scientific and engineering terms.
