Brain arousal and information theory

the long version

"Donald Pfaff argues that, beneath our mental functions and emotional dispositions, a primitive neuronal system governs arousal. Employing the simple but powerful framework of information theory, Pfaff revolutionizes our understanding of arousal systems in the brain. Applying his hypothesis to heightened states of arousal - sex and fear - Pfaff shows us how his theory opens new scientific approaches to understanding the structure of brain arousal. Brain Arousal and Information Theory challenges current thinking about cognition and behavior. Whether you subscribe to Pfaff's theory or not, this book will stimulate debate about the nature of arousal itself."--Jacket.
