The first English-language publication of the complete works of the great Spanish neurohistologist, Santiago Ramon y Cajal, on the cerebral cortex. It is amazing to read Cajal so many years after the original publication and find that despite all the technical advances he is still fresh, readable, accurate, and valuable. To have the English translation done by two neuroscientists, one of whom is a native speaker of Spanish, is the best of possible worlds. We have had to wait a long time for this book, and many will feel that they must have it. –Dr. Pasko Rakic, Yale University School of Medicine
