If you're not sure where to begin, Chapter 1: Nervous Systems is the natural starting point.- Nervous Systems — An overview of the nervous system's major structures, from the spinal cord to the brainstem , up through subcortical regions and the cerebral cortex. The various brain regions contribute and interact to produce sensation, thought, emotion, and behavior.
- How Neurons Work — How individual neurons communicate through release of neurotransmitters that excite and inhibit receiving neurons.
- Sensory Systems — How the brain processes information during vision, hearing, touch, and other senses, with an emphasis on vision.
- Movement (coming soon) — How signals from the frontal lobe, parietal lobe, basal ganglia, and cerebellum allow us to generate voluntary and automatic movements.
- Sleeping, Waking and Circadian Rhythms (coming soon) — The brain's internal clock, slow-wave sleep and dreaming, and what's known about the neural bases of sleep disorders.
- Hunger (coming soon) — The physiological and neural signals that govern hunger and satiety, as well as obesity, anorexia and other disorders of weight regulation.
- Sex (coming soon) — The hormonal and neural basis of sexual development, behavior, sexual preference, and gender identity.
- Brain Development and Plasticity (coming soon) — How the nervous system develops from before birth through adulthood, and how experience reshapes the brain across the lifespan.
- Long-Term Learning and Memory (coming soon) — What are the different types of learning and memory? How does the brain store memories and retrieve them?
- Attention and Working Memory (coming soon) — How does the brain focus on particular objects from among all those around us? How do we hold information about an object in mind after it is no longer present?
- Reward, Reinforcement, and Addiction (coming soon) — The brain's reward circuitry, including the role of dopamine in natural rewards and addiction to drugs.
- Stress, Fear, and Anxiety (coming soon) — How does the brain and the periphery of the body respond to stress and threat? What goes wrong in anxiety disorders.
- Neuropathology in Neurology and Psychiatry (coming soon) — An overview of four major neurological and psychiatric conditions: depression, schizophrenia, Parkinson's, and Alzheimer's disease.
- Higher Cognitive Function (coming soon) — What are the specialized functions of the two hemispheres of the brain? How does the brain produce and understand language? What do we know about the neuroscience of self-reflective thought and predicting the intentions and behaviors of others.
