As indicated in the preface, this chapter is not intended to be a detailed atlas of neuroanatomy. Its aim is simply to illustrate the principal anatomical structures in the brain, using photographs rather than diagrams, that should be recognised by a competent pathologist, if only to allow him to state reasonably precisely the site of any lesion identified post mortem. Provided slices of uniform thickness have been cut as described on p.104 using a very simple technique, the pathologist will also be able to measure the size of any abnormality with a reasonable degree of accuracy.

The first four illustrations demonstrate the principal structures on the medial and lateral surfaces of the brain and at the base of the brain. These are followed by a series of coronal slices of the cerebral hemi-spheres. Fig. 8.11 includes the mamillary bodies and represents the first cut made in the cerebral hemispheres as suggested on p.100. Thus Figs. 8.5 to 8.10 are anterior to this first cut, and Figs. 8.12 to 8.20 behind it. With the aim of illustrating as many levels as possible, Figs. 8.11 to 8.17 have been cut at 5 mm intervals using angles 5 mm thick but similar in all other respects to those illustrated in Fig. 7.9. We have attempted as far as possible to restrict key numbers to one hemisphere so that the corresponding structure in the other hemisphere can be clearly seen. Finally, there are illustrations of the cerebellum and the brain stem obtained as shown in Figs. 7.18 to 7.21.
