Quantitative electroencephalogram (qEEG) is the transformation of the EEG by spectral analysis in which the amount of electrical activity at a particular frequency is determined and compared against a normative data base. EEG findings are specific for different psychiatric problems and help reveal brain abnormalities associated with psychological symptoms. Repetitive transcranial magnetic stimulation (rTMS) is a system of delivering multiple pulses within a short time period that induce changes that outlast the stimulation period. Operant conditioning involves providing a reward to increase the probability of a certain behavior. Neurofeedback involves recording, analyzing, and presenting results of qEEG analyses in near real-time to patients in order to promote changes in brain electrical activity. This chapter reviews how neuromodulation works both clinically and from a neurophysiological perspective. This chapter also reviews current clinical data on the use of neuromodulation approaches for improving mental health and well-being.
