BRAIN BYTES

From the history of neuroscience to how the brain gets represented in contemporary popular culture, the authors tackle queries such as "Does size matter, and do humans have the largest brains?," "Are there foods that make people smarter?," "Does watching TV, playing video games, or surfing the Internet kill brain cells?," "Why do we dream?," "Can memories be implanted?," "Why can’t I tickle myself?," "Why do we yawn and why are yawns contagious?," and "What is the most common mental health issue?" The questions are organized into 12 general topic areas, including intelligence, memory, the senses and perception, technology, medicine, and brain health.
