EEG Neurofeedback

Electroencephalography (EEG) neurofeedback is a neoteric tool that uses principles of operant conditioning to modify brain function. This chapter introduces the reader to the foundations of EEG neurofeedback training, highlighting critical studies that led to its development. Neurofeedback research has primarily focused on clinical conditions such as attention deficit hyperactivity disorder (ADHD). The standard protocols of neurofeedback for ADHD are considered to be ‘Efficacious and Specific, Level V’ in keeping with guidelines of the Association for Applied Psychophysiology and Biofeedback. However, research in neurofeedback in other domains is still in its infancy. This chapter attempts to familiarize the reader with concepts of EEG that are relevant to neurofeedback. These concepts would include a review of standard band frequencies and electrode placement using the international 10–20 system. Neurofeedback has a wide range of applications, from the enhancement of performance to the treatment of severe clinical symptoms. Research pertaining to these applications will be discussed. The evolution of protocols and mechanisms over time in the history of neurofeedback will also be reflected. Outcome measures in neurofeedback have typically focused on EEG and clinical changes following the intervention. The need for other measures will be highlighted, offering implications for both basic and applied research. The chapter will conclude with deliberations on critical issues in the practice and research of neurofeedback.
