Excerpt: ...formed by the divergence of the right and left peduncles, or stems, as they emerge upward from out the Medulla Oblongata, and continuing upward until they unite with their respective hemispheres of the cerebrum--brain. You will observe that it is apparent that when those "stems" are brought nearer together, those two small spheres are also brought nearer together, and that, upon those "stems" being separated more widely that those two small spheres are also more widely separated, moving in uniformity as they do, and that when those ' stems' are sufficiently separted those two small spheres are separated sufficiently to form a space, or break, between them. Dr. Trall says: "These two small globular bodies are white, and about the size of a pea, and are between the peduncles." (The Doctor here uses the same term that Dr. "Whitehead does in describing the Crura Cerebri--"stems.") They are composed of nervous fibres and form a part of the great nerve-wiring system within the human brain. They are located each upon one side of the fissure existing between the right and left hemisphere of the brain, one belonging to the right side set of nerve-wires, and the other to the left side set, and with their "breaking contact" one from the other, there is caused a "break" between these right and left sets of nervewires. The Author claims that the point for breaking the electrical thought circuit within the human electrical power plant is at the mammillares, those two small white spheres so fully above described; that when they are in close contact one with the other, thought transmission is taking place, the operator being then on active duty; and when they are not in contact, one with...
