Is there any technology to control the brain waves?

Answer

There is a technology called brainwave entrainment that uses audio to alter or influence brainwave activity.

Basically, you listen to a special audio CD with a pair of stereo headphones. In one channel a particular frequency is introduced, and in the other a slightly different frequency is played. The difference between the two signals is called a beat frequency. The developers say that the brain interprets this beat frequency, and causes brainwave synchronization at the beat frequency between the two hemispheres of the brain.

There are a number of commercial producers of these disks. Hemi-Sync, HoloSync and Dr. Jeffrey Thompson are some of the more well known producers. I've tried them and found them to be very relaxing. Whether this is due to a measurable effect on my brainwaves I don't know but there is something happening when I listen. I prefer the Jeffrey Thompson CDs because they are more musical. Visit their websites for more info. There are also software packages that allow you to create you own brainwave entrainment audio.

Answer

Yes. It's called the electric chair, and it makes the brain waves stop very quickly.

Answer

I loved the last answer best but yes there is. It's called an alphawave inducer. Basically, a set of flashing lights that fill your entire field of view (that parts important) and that blink between 3 and 7hz. The blinking lights cause the brainwaves to sync with them.

I've built one once using plans from an electronics mag and bought one that I use now for about $50. There are also high end devices (called NovaPro or something like it) that do the same thing for hundreds of bucks.

And yes they really do work. Great for relieving stress or getting rid of a tension headache. The first one I built was a set of swim googles with leds in the center of them and a rubber coating poured over them. The electronics was a quick 555 timer circuit run off a 9 volt battery. Nothing complicated.
