The Spinning Disk

You have to love the classic, now cliche, spinning disk as a hypnotic tool. You know the one - the disk is divided into four parts, two black and two white that merge together when spun. Simply mesmerizing.

Well, in the interest in studying the famous masters of this art form and our talk about Charcot's hypnotic sessions, I was hoping to find an induction that he used. I have not given up on it, but it is taking some time. But what I did come across was a reference to a tool he or his assistants may have utilized for hypnotizing his patients. Indeed it was a spinning disk. However, it is described as being a four-inch long cylinder that is about one and half inches in diameter. Within this is a little spinning disk, black and white segmented as mentioned above. Without spinning the disk, it is placed three inches away from a midpoint between the eye brows (eye fatigue inducing). After a few moments there is a button on the cylinder that starts the revolution of the disk. The patient is told to concentrate on it. The theory is that as the patient does this it causes a state of suggestibility.

It is good to know that somethings don't change.
