Brain Rules - A popular book about brain and cognitive science 'rules' by John Medina. Medina is a molecular biologist interested in brain and cognitive science. His book distills some of the most important principles uncovered by cognitive and brain scientists such as the importance of exercise and sleep in improving cognition and promoting neural growth. Each of these 12 rules is really a principle or a discovery. The book makes for interesting reading and is backed up by peer-reviewed research. Unfortunately, Medina does not include references in the book. They're collected at this website. Also at this website are videos and other materials to enhance and reinforce the claims made in his book.
