Paul Tyler brings us up to-date on findings related to electromagnetism. He reports that the National Institute of Mental Health studied rats addicted to morphine and found that current stimulation to the lower part of the concha (posterior to the external auditory meatus) precipitated signs of morphine abstinence.
Researchers (Sjolund, Clement-Jones, Salar and others) have reported an increase in B-endorphins in cerebrospinal fluid following electro-acupuncture and other forms of electrotherapy. Increased rat brain levels of serotonin, tryptophan and hydroxyindole acetic acid have been reported. Numerous studies show changes of calcium ion levels in the brain following the use of magnetic fields.
It is believed that the body's own production of B-endorphins is turned off by drug addiction and that electro or magnetic stimulation enhances the natural production and release of encephalms and £3-endorphins by the body, preventing the onset of withdrawal symptoms. Tyler speculates that calcium is the critical factor and not the endorphin system. He further states that modern medicine has studied and treated the chemical side of the equation but has almost completely ignored the electrical/magnetic side.
The body's natural chemicals are released by an electrical signal so it seems plausible that an external signal can do the same at a specific site without drugging the rest of the body.
