Book excerpt: A groundbreaking investigation of the brain’s hidden logic behind our strangest behaviors, and of how conscious and unconscious systems interact in order to create our experience and preserve our sense of self. From bizarre dreams and hallucinations to schizophrenia and multiple personalities, the human brain is responsible for a diverse spectrum of strange thoughts and behaviors. When observed from the outside, these phenomena are often written off as being just “crazy,” but what if they were actually planned and logical? NeuroLogic explores the brain’s internal system of reasoning, from its unconscious depths to conscious decision making, and illuminates how it explains our most outlandish as well as our most stereotyped behaviors. From sleepwalking murderers, contagious yawning, and the brains of sports fans to false memories, subliminal messages, and the secret of ticklishness, Dr. Eliezer Sternberg shows that there are patterns to the way the brain interprets the world—–patterns that fit the brain’s unique logic. Unraveling these patterns and the various ways they can be disturbed will not only alter our view of mental illness and supernatural experience, but will also shed light on the hidden parts of ourselves.
