Indeed very short, Corballis's little nuggets were full of exciting current ideas about the brain, a topic getting more and more popular (dare I say 'headway'?). Many topics have been covered elsewhere, but I appreciated his frank criticism of popular theories and offerings of his own alternatives (eg about the evolution of language). I highly recommend this book even though it's quite short (or esp because it's so short!): it offers more than it's share of information and insight.
