BARR'S The Human Nervous System: An anatomical viewpoint, 9th Edition

Preface to the Ninth Edition

Murray Llewellyn Barr (1908-1995) obtained his medical degree in 1933 from the University of Western Ontario in London, Canada, and after a few years in practice, he entered the Department of Anatomy at the same institution. He studied and taught neuroanatomy there until 1978. This period of service was interrupted by the Second World War, when he served in the Medical Branch of the Royal Canadian Air Force. In 1949, the direction of Barr's research changed abruptly from neurohistology to cytogenetics. With Ewart G. (“Mike”) Bertram, who was then a graduate student, he had observed an intranuclear inclusion in neurons of female animals. This was the sex chromatin, now widely known as the Barr body; its discovery was an early landmark in the science of human cytogenetics. For this and his later work in the field, Murray Barr received more than 30 awards and honors, including the Kennedy Foundation International Award in Mental Retardation, Fellowship of the Royal Society of London, the Order of Canada, and seven honorary doctorates.

Although Barr's research career was largely concerned with the cytological diagnosis of inherited diseases, he continued to teach neuroanatomy. The first edition of this book, published in 1972, was one of the first medium-sized texts in its field. It was written to make life easier for those approaching neuroscience for the first time, especially medical students and those in the allied health sciences. This objective has not changed, although a greater variety of students now study the subject. Advances in the science necessitated much revision over the years, and the book became larger with successive editions. With the Eighth Edition, this trend was reversed, resulting in a somewhat smaller book. The illustrations were enhanced, however, with more extensive use of colors.

New to This Edition

In this Ninth Edition, the improvement and changing of illustrations has continued, and nearly all are now colored. The text and recommended readings have, of course, also been updated. Readers of this edition have access to the publisher's Web site—www.lww.thepoint. com—which includes a variety of additional materials. These include labeled and unlabeled versions of all the illustrations for instructors, sample exam questions and clinical cases, an extended glossary, and biographical information about researchers and physicians whose names are associated with anatomy, physiology, and diseases of the nervous system. The-Point also carries expanded versions of some chapters. A marginal icon in the printed book indicates subjects for which additional material is available online.
