- toddb@vu-vlsi.ee.vill.edu (Todd Blakaitis) asks:
- TO>** Has anybody ever tried those "Mind Machine" glasses with the blinking
- TO> led's and headphones? They claim to introduce a hallucinagenic-like (sp
- TO> state?!?!?!
-
- Yes, my wife and I have one called "MasterMind" which we bought at an
- outrageous price from the Hammacher Schlemmer catalog. It definitely
- has an effect, but whether it's anything like chemical hallucinogens I
- can't say due to lack of experience. (Honest!)
-
- The unit consists of a small black box containing the electronics, a set
- of earphones, and a set of opaque "sunglasses" with four red LED's (2 on
- a side) mounted so they will flash in your eyes. (Note: you use this
- device with your eyes _closed_.) The idea is that your brain waves will
- synchronize to the flashing lights, and you will be drawn into various
- medidative states associated with the different frequencies. The unit
- also provides pulsing sounds via the earphones to intensify the effect.
-
- You can select any of a dozen "sessions" of 10 to 40 minutes duration
- (plus another dozen that are half-length versions of these). The
- different sessions follow different patterns of moving between high and
- low frequencies. There are also some user-unfriendly controls for
- volume, pitch, brightness, etc.
-
- The device really does do more-or-less what it claims, in our
- experience. You would think that having bright rapidly-flashing lights
- next to your eyelids would be unpleasant, but it's not. As for
- "hallucinogenic", here's what you get: At high flash frequencies (10 to
- 30 Hz or so), the eyes and/or the visual center of the brain generate
- all sorts of lines and swirly things and plaids and geometric patterns
- in red and blue and yellow. The pattern varies with the frequency and
- with how the lights are synchronized (both eyes together, or
- alternately). I found the patterns to be overwhelmingly brilliant the
- first time I used the device, but less so after I got used to it. (The
- human mind seems to have an infinite capacity for getting bored!)
-
- At lower frequencies there is very little "light show", and the effect
- is hypnotic. I assume this is the "alpha state" that people achieve
- with meditation. Yet lower frequencies (a few Hz) take the user into a
- light doze. A typical session with the machine starts at the
- high-frequency end, slowly wanders down into the lower range, and then
- comes back up again at the end to wake you up and give you a final light
- show.
-
- Sometimes, when the frequency starts to increase from its minimum, I
- will notice what feels like a flood of warmth and general well-being
- spreading out through my body. There's some actual physical effect
- here: cold feet and hands become warm, for example. I suppose some
- hormone is being released. This doesn't happen every time (and I can
- ruin it by waiting for it to happen).
-
- I use this device for a "controlled nap" -- I can set in advance exactly
- how long it will be and how deep, and ensure that I wake up gently.
- Five minutes is enough to relax computer-strained eyes, but 10 to 40
- minutes is needed to really give my brain a reset.
-
- I know someone who used one of these along with a moderate dose of
- dextromethorphan, and had a loss-of-ego experience ("I couldn't
- distinguish what was me, what was the light show, and what was the bed
- I was lying in"). If anyone has used one in conjunction with other
- psychoactive materials, I'd like to hear about it.
-
- WARNING: THESE DEVICES CAN TRIGGER SOME FORMS OF EPILEPSY! Remember the
- epileptic researcher in "The Andromeda Strain" who got knocked out by a
- flashing computer display? That part wasn't fiction.
-
- I suppose this really ought to be in alt.cyberpunk.tech. But it's not.
