Summary
Changes in the intramural nerve ganglia and in the myocardium caused by experimentally induced compensatory cardiac hyperfunction followed a definite pattern. During the first stage there was an edema of the neurones, various stages of diffuse lysis of the Nissl substance, and vacuolization of the processes of the nerve cell. The second stage was one of relatively stable hyperfunction, during which the edema disappeared from most of the neurones. A small proportion of the neurones were irreversibly damaged, and died.
