Therapists have long recognised the role of brain chemistry in mental illness, but new thinking reveals that brain circuitry - its very rhythmic oscillations - plays an equally critical role in determining whether we function from a core position of regulation and emotional stability, or one of dysregulation and volatility. Indeed, how we are wired, and the very frequencies at which our brain operates, largely dictates how we behave in the world. In this groundbreaking book, Sebern F. Fisher explores the complexities of attachment trauma and self regulation, showing how neurofeedback training - a therapeutic protocol that teaches the brain to operate at different, more tranquil frequencies - can transform the circuitry of a brain seized by the fear and rage of early attachment wounds and restore calm.
