With its trillions of connections, the human brain is more beautiful and complex than anything we could ever build, but it’s far from perfect: our memory is unreliable; we can’t multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but.

Weaving insights from philosophy, neuroscience, and history into a rich narrative, The Shallows explains how the internet is rerouting our neural pathways, replacing the subtle mind of the book reader with the distracted mind of the screen watcher. A gripping story of human transformation played out against a backdrop of technological upheaval, The Shallows will forever alter the way we think about media and our minds.

From Parkinson’s disease to Tourette’s syndrome and depression to psychopathy, Broken Brains reveals the mysteries of brain function - and dysfunction. In this no-nonsense introduction, Ian Mitchell takes you on a tour through the sometimes devastating and sometimes bizarre effects of what happens when brains break down.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

With the lucid verve and solid scientific grounding of an Oliver Sacks or Malcolm Gladwell, Dr. Brian Boxer Wachler guides listeners on a fascinating tour of the bedrock of our existence - the way our senses perceive everything and everyone in the world around us. Why does one person see Jesus in a shower curtain, get a "bad feeling" about someone they've just met, or hear a conversation so differently than the other person? Boxer Wachler describes some of the mysterious medical conditions that cause non-psychiatric hallucinations and neurological mix-ups.

People behave in strange ways. We sometimes giggle when someone falls down, swear we've been to places we haven't, or continue believing in something despite scientific evidence to the contrary. For more than a decade, Scientific American MIND's long-running feature "Ask the Brains" has addressed questions from their readers on the quirks and quandaries of human behavior, psychology, and neurology. Here, in Ask the Brains, Part 1, they’ve compiled some of the best and most interesting inquiries about the human brain.

Losing your memory? Can't focus or concentrate? Do you have brain fog or tire easily? Have you lost your zest for life or motivation? Do people tell you this is all a normal part of aging? If so, your brain may be growing old too fast, or degenerating. Modern diets, a stressful lifestyle, and environmental toxins all take their toll on the brain. This doesn't just happen to seniors - brain disorders and degeneration are on the rise for young and old alike. The good news is the brain is extremely adaptable and wants to get well.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.
