In The Man Who Tasted Words, Guy Leschziner leads listeners through the five senses and how, through them, our brain understands or misunderstands the world around us.

Vision, hearing, taste, smell, and touch are what we rely on to perceive the reality of our world. Our five senses are the conduits that bring us the scent of a freshly brewed cup of coffee or the notes of a favorite song suddenly playing on the radio. But are they really that reliable? The Man Who Tasted Words shows that what we perceive to be absolute truths of the world around us is actually a complex internal reconstruction by our minds and nervous systems. The translation into experiences with conscious meaning–the pattern of light and dark on the retina that is transformed into the face of a loved one, for instance–is a process that is invisible, undetected by ourselves and, in most cases, completely out of our control.

In The Man Who Tasted Words, Guy Leschziner explores how our nervous systems define our worlds and how we can, in fact, be victims of falsehoods perpetrated by our own brains. In his moving and lyrical chronicles of lives turned upside down by a disruption in one or more of their five senses, he introduces readers to extraordinary individuals he’s worked with in his practice, like one man who actually “tasted” words, and shows us how sensory disruptions like that have played havoc, not only with their view of the world, but with their relationships as well. The cases Leschziner shares in The Man Who Tasted Words are extreme, but they are also human and teach us how our lives and what we perceive as reality are both ultimately defined by the complexities of our nervous systems.

A renowned neurologist shares the true stories of people unable to get a good night’s rest in The Nocturnal Brain: Nightmares, Neuroscience, and the Secret World of Sleep, a fascinating exploration of the symptoms and syndromes behind sleep disorders.

For Dr. Guy Leschziner’s patients, there is no rest for the weary in mind and body. Insomnia, narcolepsy, night terrors, apnea, and sleepwalking are just a sampling of conditions afflicting sufferers who cannot sleep–and their experiences in trying are the stuff of nightmares. Demoniac hallucinations frighten people into paralysis. Restless legs rock both the sleepless and their sleeping partners with unpredictable and uncontrollable kicking. Out-of-sync circadian rhythms confuse the natural body clock’s days and nights.

Then there are the extreme cases. A woman in a state of deep sleep who gets dressed, unlocks her car, and drives for several miles before returning to bed. The man who has spent decades cleaning out kitchens while “sleep-eating.” The teenager prone to the serious, yet unfortunately nicknamed Sleeping Beauty Syndrome stuck in a cycle of excessive unconsciousness, binge eating, and uncharacteristic displays of aggression and hypersexuality while awake.

With compassionate stories of his patients and their conditions, Dr. Leschziner illustrates the neuroscience behind our sleeping minds, revealing the many biological and psychological factors necessary in getting the rest that will not only maintain our physical and mental health, but improve our cognitive abilities and overall happiness.
