Neuropsychiatry and Quantitative Electroencephalography (qEEG) in the 21st Century

The human brain weighs about 3 pounds and consumes 40% to 60% of blood glucose. This disproportionate amount of energy is used to create electricity in about 100 billion interconnected neurons. Quantitative electroencephalography (qEEG) is a real-time movie of the electrical activity of the preconscious and conscious mind at frequencies from about 1 Hz to 300 Hz. Numerous studies have cross-validated Electrical Neuroimaging by structural MRI, fMRI and Diffusion Spectral Imaging (DSI) and thereby demonstrated how qEEG can aid in linking patient’s symptoms and complaints to functional specialization in the brain. Electrical neuroimaging provides an inexpensive millisecond measure of functional modules including the animation of structures through phase shift and phase lock. Twenty first century Neuropsychiatrists use these methods to link patient’s symptoms and complaints to functional specialization in the brain and use this information to implement treatment via Brain-Computer-Interface and neurofeedback technology.
