Scientists Create Lullabies From Brain Waves 239

Posted by CowboyNeal from the songs-stuck-in-your-head dept.
Lord Custos writes "From ABC News: Your Brain Waves are Better than Sleeping Pills! Everyone has a song in them...literally. And you can use it to put yourself to sleep. Canadian scientists have discovered that deep sleep can be induced in insomniacs by copying the insomniacs brainwaves, turning it into 'music', and then playing this 'audio transcription' of their own sleep brainwave pattern back to them."

    Isn't this actually 'old'? It's a well known fact you synchronize your brainwaves to the music you hear if it falls into an acceptable pattern. Heck, even look at commercial stuff like CoolEdit, which has a brainwave pattern generator built in for editing music. It even has some scripting to make your brain ready for specific things (like sleep brainwave patterns).

    There are even commercial devices based on the concept. Like the flashing-glasses-beeping-headphones combo machines. And it seems only natural that you'd sleep better when you can listen to a sleep brainwave pattern tuned exactly to yours, instead of a 'general' one...

        i do know about lucid dreaming, even though i very rarely manage to have one. the lucid dreaming devices are usually different in that they are timed to bring you back to consciousness in your sleep at a predefenide time.

        THERE ARE devices that are solely for the brainwave stimulation approach, NOT for lucid dreaming (although they could be used for that purpose)
      • Those are for LUCID DREAMING.
        There are goggles that blink a few times to indicate that the dreamer has entered the REM stage of sleep. When the dreamer sees the blinking in the dream, it's a reminder that it's a dream and it serves as a cue to have a lucid dream. But that's not what the poster is referring to.

        The poster is referring to "light and sound machines", which can induce brainwaves using blinking lights and beeping. They're great for helping to induce a hypnotic state and also to induce sleep. Do a Google search to find out more...

    • Kind of along similar lines - I participated in several "brain training" sessions where I was hooked up to a computer and when my brain waves were in a sweet spot, a tone would sound. The tone was interpreted as positive reinforcement by my brain and over time my brainwaves adjusted to the more efficient state. This allowed me to sleep better, concentrate better, etc. Kind of related to what you're talking about, but cooler.

  • Filter out the differences among various subjects, figure out what the common patters are and we'll have a nice, common bit that should work for anybody. Cool idea. I don't have trouble sleeping most of the time, but this would be nice to have at my disposal for those "project crunch" moments.

        > Where did you come up with that idea?

        It's a logical extension of the "conclusions" presented in the article. We assume that since most of us non-meth-snorting humans have common brainwave characteristics that there should be common sonic patterns that will help induce relaxation and/or sleep.

        It's not much different than chanting-based meditation techniques except that whereas saying "ooooohm" is based on religious practice, we now have a way of analyzing things in a scientifically sound fashion that, by rights, should be reproducible.

        Of course, while some will be studying how to use such tones to relax and induce sleep, you wanna bet yer sweet bippy that there are going to be Very Secret Places studying how to use these same techniques to induce stress, terror and other psychological trauma.

    "For the placebo group, the improvement was only about 15 percent as compared to 75 to 85 percent for the experimental group. So it's a highly significant statistical difference," Kayumov says. It also shows that brain music is highly individualistic.

    It worked, he adds, because the sleep music was lower in frequency than other brain waves and induced kind of a relaxed, meditative condition. In other words, each subject's brain recognized its own lullaby and reacted accordingly.

It seems to me that it could addictive. Many addictions result from the body lowering production of naturally ocuring substances because it's being replaced with the addictive substance. Remove the substance and you go into withdrawl. Who's to say that, over time, the brain wouldn't lose the ability to generate these patterns naturally?

      But it would depend on your definition of "nap". Does it last 1 hour? 2 maybe? I seem to recall the garbage collection stuff being related to REM sleep, which starts about 1 hour into your sleep (figure pulled entirely from memory). So naps of 2 hours or so should definately help you keep your mind, but in the long run you'll probably just have to come to turns with the fact that we're DESIGNED (creationist?/Darwinist? - still true) to need sleep.

A more convenient solution that is already in use in infant soothing toys is a simulated heartbeat noise, like the kind a fetus would hear while inside the mother. It reminds the baby of being inside the womb, and comforts them into falling asleep faster. But I've found that this also works well even on adults, as I think this "comfort pattern" that is etched in our brains from before birth remains in our subconscious as long as we live.

    this reminds me of schumann resonances.. you can read about them at: http://www.innerx.net/personal/tsmith/Schumann.htm l [innerx.net]

    i was telling a buddy about these and he recommended i check out http://www.bwgen.com/ [bwgen.com] .. its a sound generator that can create a wide variety of frequencies (including shumann resonances) .. i have found several presets all over the place and now i use it to relax, to fall asleep, to study for that big test.. many applications :]

  • The good Doctor (Asimov) wrote a story about this very effect: "When the Saints".

    In the story, a musician is hired by a psychologist to assist in a research project. They are recording the brainwaves of depressed patients, diffing them against the brain waves of normal folks, inverting the difference, and feeding that back into the patient with sound and laserlight. It works, sort of, for a while.

    They hire the musician because (rough quote) "...while the laser light is precise enough to convey the information, the sound isn't. We need somebody to work out what part of the sound is important, and what part isn't."

    The musician takes the tapes and goes away for a while. When he returns, he says, "Here's a tape. Try this." The psychologist cues the tape up for the patient. After the session, the patient says "I think I'm cured - before I always could feel the depression in the back of my mind, but it's gone now!" "Did you notice anything different about the therapy?" "Well, maybe the light was a bit sharper..." "What about the sound?" "I really didn't notice the sound..."

    After the patient leaves, the psychologist asks the musician what he did, and would he consider a position on the staff.

    (Roughly quoting the musician)
    "No need - the work's already been done. I noticed the patterns were like some music I know - revival hymns. I gave him the best of the lot - When The Saints Go Marching In"

    Dr. Asimov wrote this for an Audio magazine, and the story appears in some of his story collections. Good stuff.
  • my inner monologue of music music by chance be the right stuff to put me out. I can sleep pretty much all the time unless I have major stimulants in my system.
    in fact, today I slept through my alarm and was late for work.

    also, for me personally, if I turn up classical music I get vaguely annoyed and can't sleep - but if I crank say Tool, Rage Against the Machine, or even older stuff like Killing Joke - then I'm out like a light.
    My freshman year of college I scared my roommate on the first day there by falling asleep on the floor with White Zombie blasting on the stereo. he opened the door into my head and I didn't wake up.

    I personally don't care about these studies to help me sleep - I do that quite well. I want to know how to stay awake.
  • This kind of work has been done for about 25 years at The Monroe Institute [monroeinstitute.org] in Virginia, USA. They have a number of recordings of brain synchronization tones available for sale that induce sleep, deep trance states, and encourage self-awareness in various ways.
    Some of them come with voice overlays to encourage the user to have certain kinds of insights and experiences. It's great to see this kind of research becoming more mainstream; there's a lot of potential for helping kids with ADD, insomniacs, etc.

  • Hebb's principle (Score:5, Interesting)

    Assuming that the pattern of brain activity is always roughly the same when you're trying to fall asleep, this follows logically from a tenet of biological psychology called Hebb's principle. It states that when two neurons fire together, the connection between them is strengthened.

    To explain, I'm going to invent a symbology. X,Y,Z, and K represent neurons in different regions of the brain. I'll create an arbitrary pattern that represents when each of those neurons fire. Let's say that as you fall asleep you normally have a pattern like: XYZYYKKZXK. (I intentionally avoided using A, B, C here for the musical connotations therein.) Let's say it's mapped into music now:
    XYZYYKKZXK (neurons firing)->
    ABCBBGGCAG (notes played)

    When you hear the note A, a particular region of your auditory centers is activated. When you hear B, a slightly different region is activated, and so on. Coincidentally, a lot of your auditory processing takes place in your brain stem, which is also where a lot of sleep-related functions take place, such as shutting down the body's muscles so you don't sleepwalk every night, but this coincidence isn't necessary for this explanation to work.

    So you listen to your personalized auditory mapping and attempt to fall asleep. Because you're trying to fall asleep, even if you're insomniac, neurons for X will be a little more likely to fire, then neurons for Y, then Z, and so on. At the same time, neurons for A are firing, then B, then C.

    According to Hebb, the synchonicity of these events will cause a physical connection between the neurons to strengthen, regardless of how much neural distance separates them. All the neurons in between will get activated a little bit, and the more they fire together, the more the entire system of connections becomes stronger. You've directly mapped sleep waves into music, so the synchronicity will be very strong. Consequently, the connection between the auditory centers and your sleep centers will get stronger very quickly.

    Make that connection strong enough, and you will eventually be able to cause XYZK to fire by playing ABCG, in essence sending a message to your brain stem via your speakers. Do this long enough, and the feedback may go in the other direction as well: you may start to hear the music every time you fall asleep, regardless of whether it's actually playing.

    Theoretically this would work by mapping those brain waves into just about anything you can perceive, not just sound, although it may work better with sound. For example, mapping it into images would certainly work; you could take the entire discussion above, replace "auditory centers" with "visual centers", and you get the same explanation.
  • Can we measure brain waves when people are excited, or sexually aroused, and then make music out of that? I bet it would sell like crazy.
  • Well! This is a most interesting discovery. Let's take a quick trip into the minds of various people in various cultures, and find out just what they've got knocking around in their gray matter.

    From the mind of a somewhat suicidal insomniac in San Francisco: Van Halen's "Jump."

    From that of a gay preacher in Biloxi, MS: Barry Manilow's "It's a Miracle."

    From the neurons of the 3M rep for adhesive products in Irkutsk, Russia: Lionel Richie's "Stuck on you."

    A cabbie on the run from Heathrow airport in London to the downtown hotels was found to have "You Picked a Fine Time to Leave me, Loose Wheel" rattling around in his skull (and lug nuts rattling around in his trunk -- pardon me, 'boot').

    In Australia, a most sleepless LAN technician, one Arthur 'Sparks' McGill, was startled to find Icehouse's "Electric Blue" firmly embedded in his alpha waves.

    Finally, back here in the States, Slashdot's owner, Rob "Commander Taco" Malda surprised no one by having that (in)famous filk track Mr. Compatibility [ohio-state.edu] stuck so firmly in his brain stem that not even a jackhammer was able to dislodge it.

    That's all for now. Tune in again next week for another installment of "Spot the Looney!"
