The atlas is a set of photomicrographs of technically excellent sections of the brain of the laboratory rat. Each plate consists of matching cell and fiber stains labeled for neuronal groups and axonal tracts, respectively, with abbreviations directly on the appropriate structures and annotations explaining criteria, and other problems of nomenclature, for structures requiring commentary. Structures can be traced in photomicrographs in sagittal, horizontal, and transverse sections; the latter at 0.3 mm intervals, for both cell and fiber stains. The reasonable page size and sturdy binding renders the book suitable for use both at the laboratory bench and as a convenient reference. The text and tabular material provide guidance for the use of this atlas of the brain for stereotaxic placement of electrodes, or for destruction using cranial landmarks. The atlas will be useful to neuroscientists and psychologists who refer to the structure of the brain in their research and for students of brain anatomy in all biomedical fields.
