I have always found the brain's inner workings fascinating, but I don't want to get lost in medical jargon. Johnson states at the outset that he will only hit the high points, and that was what he did. The jargon was controlled and well explained, and the anecdotes were easy to follow. He repeats himself a lot, and at first I thought this was fluff to fill out the book, but then I realized it helped me remember the concept. Rather than zip from topic to topic, we dwell on one for a while before moving on to the next. This is important because each concept builds on the next.
Johnson's writing style is smooth and clever, and several times I chuckled out loud.
My only complaint is the book was too short! In the end, it doesn't cover a lot of ground. At least the ground it does cover is well done and topical. Recommended for anyone who is interested in a pop-sci version of neuroscience.
