Neuroscience is the study of the brain and nervous system. The simplicity of that true and very mechanical definition belies the ongoing work to uncover the seat of human behavior, consciousness, and memory: what exactly is the connection between our neurons and our thoughts; our glands and our feelings; our cells and our dreams? Neuroscientists strive to unlock these connections and provide answers to our questions about our purpose, perception, and connection to the world around us and each other.
