Why Brains Need Friends

"An exquisite book that reminds us our minds aren't soloists but symphony players: we are wired for connection."—David Eagleman, PhD, author of Incognito and Livewired

A neuroscientist’s guide to boosting your brain health by living a more connected life, and thriving in a post-interaction world

Headlines have made clear that we are in a crisis of loneliness, but the conversation has yet to explore how spending less time with others can impact the body and mind on a cellular level—and why this knowledge is part of the way forward. Renowned neuroscientist Dr. Ben Rein dives into the fascinating science of social interaction, revealing how our brains are wired for connection and why modern life is challenging those ancient instincts. Through the lens of neuroscience, he explains our need for community and provides new frameworks for bringing togetherness into our lives. Rein uncovers the mesmerizing biological factors at play in our moments together, from small talk with baristas to deep conversation with friends, and shares how to leverage this information to our advantage as we seek happiness and health.
