As ever with the New Scientist books, this is a great introduction to a topic — and in this case, it’s a fairly narrow topic: the brain, and how it works. It’s not just a collection of stuff that’s appeared in the other collections, although I think a few of the info boxes and so on did come from other New Scientist publications originally. It’s also based on one of their Instant Expert courses, a great series of events that I do recommend if they cover a topic you’re interested in.
For me, even without my degree, this was a fairly simplistic view of the brain — “instant expert” isn’t quite what you’d become from reading it, I’d feel. “Instantly more informed and able to understand further information with a good foundation,” perhaps.
