Welcome to the strange and wonderful universe inside your brain: the realm of neurotransmitters. These microscopically-teeny chemicals play a crucial role in every moment of your day, from how you decided what to eat for lunch to whether you swiped right or left on Tinder. Memory, meaning-making, and basic human desires such as hunger, fear, sleep, sex, snuggles, and chocolate can all be traced back to the interplay of tiny molecules in your brain. Some of them go by familiar names—adrenaline, dopamine—and others will likely be new to you. Is it our brain chemicals that cause us to be “hangry”? How do hormones and neurotransmitters affect the trajectory of our romantic relationships? The author of this mind-expanding book explores questions relevant to your daily life, using the cutting-edge science of brain chemistry to better understand your feelings and behaviors.(This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
