Introduction

The rat brain is the most widely used animal model in neurobiology. The frequency of its use underlines the need for stereotaxic atlases of the rat brain. The first attempt to fulfill this requirement was made by Krieg (1946c), but his atlas contains only very rough data based on 30 schematic drawings of coronal sections. The drawings are exaggeratedly schematic and significantly distorted. This, together with the fact that Krieg delineated far too few structures in the di- and rhombencephalon, makes the accurate placement of electrodes difficult. Accurate electrode placement is essential for advanced techniques in modem neuroanatomical, neurophysiological, and neurochemical studies. Nevertheless, Krieg's work represents the first delineation of cortical areas in the
