Excerpt from Outline of Psychiatry in Clinical Lectures The importance, which the focal symptoms attain accord ing to this definition in our subject, makes it seem advis able to keep their nature fully in mind. Through Meynert we have learned that the voluntary muscles and sense organs are connected with the cortex of the cerebrum by conduction paths, which extend in physiological continuity through the brain, spinal cord and peripheral nervous system. The sum of these paths, in which the law of isolated conduction pre vails, he calls the projection system, and thus clearly and unmistakably expresses the fact of physiological continuity in contradistinction to anatomical continuity - a fact which by recent research is proven to be perfectly true. Corres ponding to the division of the cerebrum into two hemispheres, the projection system is also divided into two halves, as is known, with the arrangement that motion and sensation of each half of the body is associated with the opposite cere bral hemisphere.* The expression projection is evidently borrowed from optics; as here the course of the rays through a system of lenses is to be followed exactly, so, in spite of all interpolation of ganglion elements in the paths of the projection system, the physiological continuity and isolated conduction are universally preserved. The majority of the focal symptoms may be readily traced to local interruption or stimulation of the conduction paths in the projection system.
