Mesmer and the Birth of Hypnosis

You gaze at a slowly spinning pocket watch. As you follow the hypnotist's soft voice, you slip almost unknowingly into a deep state of absorption.

Many people think of hypnosis as a mere magic show, or a bizarre trick for bending other people to one's will.

But is hypnosis really a scientific phenomenon that affects our brain and body, the way popular belief assumes?

The origins of hypnosis trace back to the outlandish claims of an 18th-century Austrian physician, Franz Anton Mesmer.

He proclaimed that by manipulating an invisible force flowing from the cosmos — "animal magnetism" — he could cure every illness.

But his lavish treatment rooms and mystical cures soon drew deep suspicion from the French royal court.

In response, the French crown convened a commission of the era's finest scientists, led by Benjamin Franklin.

They ran the first blind experiment in scientific history — blindfolding patients and deceiving them about whether a real magnet was even present.

The body reacted only when patients believed energy was flowing — and animal magnetism was exposed as a baseless fraud.

Though it ended as a hoax, it marked the dawn of the "placebo effect" — proof that imagination and expectation can stir real bodily responses.

Later, the 19th-century physician James Braid redefined hypnosis not as magic or religion, but through the lens of neurophysiology.

He found that intense focus on a single object can send the brain into a temporary "nervous sleep" and a powerful state of absorption.

Today, modern science has mapped its mechanism by peering into the hypnotized brain with fMRI scanners.

Remarkably, under hypnosis the activity of the anterior cingulate cortex — the region that registers pain — drops dramatically.

Thanks to this, modern medicine now uses hypnosis directly for anesthesia-free surgery in patients who can't tolerate drugs, and for intensive psychotherapy.

Hypnosis is no supernatural magic, but a precise and powerful tool of the mind — forged by human imagination and the science of the brain.
