Overview

Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them?
Your Brain, Explained is a personal tour around your gray matter. Neuroscientist Marc Dingman gives you a crash course in how your brain works and explains the latest research on the brain functions that affect you on a daily basis.

You'll also discover what happens when the brain doesn't work the way it should, causing problems such as insomnia, ADHD, depression, or addiction. You'll learn how neuroscience is working to fix these problems, and how you can build up your defenses against the most common faults of the mind.

Along the way you'll find out:
· Why brain training games don't prevent dementia
· What it's like to remember every day of your life as if it were yesterday
· Which popular psychiatric drug was created from German rocket fuel
· How you might unknowingly be sabotaging your sleep

Drawing on the author's popular YouTube series, 2-minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks from the perspective of a neuroscientist—using real-life examples and the author's own eye-opening illustrations. Your brain is yours to discover!
