Evolutionary Anatomy of the Primate Cerebral Cortex

Rating:
Summary: Good summary of research trends
Review: This is a short, very readable book, consisting of a series of brief reviews of various aspects of primate cortical evolution. There are two main sections, "The evolution of brain size," and "Neurological substrates of species-specific adaptations," each with a very helpful introductory/summary essay. A fascinating epilogue is by Harry Jerison, in whose honor this volume was written, showing how the pioneers in a field can still stay on the cutting edge of things. Two of the articles I found most illuminating were by Todd Preuss, who shows how the idea of a canonical mammalian cortical circuit diagram is a gross oversimplification, and Katerina Semendeferi, who contests the received truth that human frontal lobes are greatly expanded; in fact her work shows they are of the expected volume for a primate of our size. Pasko Rakic also presents his view of how cortical expansion could have occurred (by simply expanding the number of cell cycles in the ventricular zone), which he has presented elsewhere, but here with some new data on the role of apoptosis. However, there is not much coverage of recent advances in the understanding of regulatory molecules involved in brain development (e.g. the hox genes). The book is also a priced a bit too high in my opinion. But for those interested in this area, it is a must read, and an enjoyable one.
