First published in 1881. The present work, on the structure and functions of the brain, is an abstract of the author’s persoal experience as regards this subject. It is divided into two distinct parts; the first, anatomical, serves as the foundation of the work. It is followed by a second, purely physiological, which is its complement and necessary sequence. It includes chapters on the optic thalamus, the corpus striatum, and the memory in exercise.
