INTRODUCTION
 Human nature
 Curiosity, emotion (happiness & hurt), movement, reasoning, learning, memory (remember & forget),and madness Neuroscience definition Study of the brain / nervous system The Society for Neuroscience Association of professional scientist In need of interdisciplinary approach to understand the brain

THE ORIGINS OF NEUROSCIENCE
 Prehistoric ancestors Brain was vital to life Brain surgery (Trepanation) Aim: not to kill but cure Skulls show signs of healing after surgery Views of ancient Egypt Heart: consider as seat of soul and memory (not the brain)
