AMAZING Electrical Tests SHOW What Happens When You Think


By Edwin Teale
PIONEERS in an amazing new field of research recently traveled to the Loomis Laboratories, Tuxedo Park, N. Y., for the first meeting of its kind in America. The sixty scientists who compared notes are "brain-wave" experts, students of minute, telltale pulsations of electric current that come from the billions of cells in the human brain.
With supersensitive electricity-recording instruments, able to register less than a millionth of a volt of current, they are discovering curious facts about our brains and how they work. Already, these scientists have achieved such exciting feats as "photographing a dream," watching the electrical pattern made by brain cells in solving a mathematical problem, and witnessing an "electrical storm," piling up in the brain of an epileptic. By discovering rhythms in the varying strengths of these tiny currents, they are working toward a radically new technique in detecting and diagnosing various ailments of the brain.
