Dermatitis from Army Spectacles

which these minute intercellular formations play ? Can one doubt that in various pathological affections of the brain as a whole, and of the cerebral cortex in particular, these delicate intercellular structures are the first to be exposed to disease, being the most vulnerable? Of special interest are these data from the point of view of pathological changes of the brain in the so-called " functional diseases" of the nervous system. Obviously, in various " functional diseases," and also in many cases of psychosis, where we are not in a position to identify definite changes in cellular structure, one must assume first ot all an affection of these intercellular connexions. The examination of these amazingly fine and diverse structural formations of the cortex presents us with more problems, the resolving of which is one of the chief tasks of modern neurology and neurophysiology. The work of the research staff of the Moscow Brain Institute is dedicated to the study of these questions.
