John splits the book up into twelve different sections, each with findings in neuroscience, as well as how to apply those findings practically. These sections are
Survival: How our brain is a product of our evolution, and some traits it has adopted as a result
Exercise: How exercise improves our cognitive abilities and staves off dementia
Sleep: What the brain does during sleep, how people are biologically predisposed to various sleep patterns, and how to use naps to improve performance
Stress: The various biochemicals involved with stress and how to have less stressful relationships and life
Wiring: How neurons interact, develop, and function
Attention: How multitasking works (or doesn't work), the relationship between emotion and attention, and the need for relaxation to enhance focus
Memory: How memory formation works and the optimal way to remember things
Sensory Integration: How all of the senses work together to provide a cohesive experience, and how multiple senses can be utilized to improve learning
Vision: How vision trumps all of the other senses and can be used to create more effective presentations
Music: How music can cause improvements in cognition, be therapeutic, and how music training can improve cognition
Gender: Differences between the genders in physiology, socialization, emotional reactions, and memory.
Exploration: How the brain is constantly exploring and looking for novel things
A lot of reviewers have pointed out that many of the tips that John gives are common sense - that may be true. However, I found that knowing the neuroscience behind many of the things which John advocates ensures their adoption into day-to-day life.
Overall, a great read that has caused me to change the way I give presentations, how much I exercise and sleep, as well as how I interact with people.
