Welcome to IOU Digital Library

This book presents a bold, interdisciplinary theory of brain arousal grounded in neuroanatomy, neurophysiology, genetics, and information theory. Pfaff argues that beneath cognitive functions and emotional states lies a primitive, bilaterally symmetric arousal system common to mammals, responsible for responsiveness to stimuli, locomotion readiness, and emotional reactions. The book reviews the anatomy and neurochemical pathways of arousal mechanisms, explores gene networks supporting them, and applies information‑theory concepts to quantify and model generalized arousal — offering a unified framework for understanding arousal’s role in brain function, behavior, and mental states.
