Thread: Ultrasound to induce Lucid Dreams?

does anyone know how I can get my hand on any low frequency Ultrasound devices?

a hospital? lol

I dunno, seems quite ballsy to me to start screwing with your head like that. I wouldn't do it unless I knew precisely what I was doing, which I don't. I'm cautious about things like this though, I don't even like the idea of binaural beats because I have no idea what they are actually doing or if the person who made it was qualified to screw with my head

"One prior stumbling block to using ultrasound noninvasively in the brain has been the skull. However, the acoustic frequencies utilized by Tyler and his colleagues to construct their pulsed ultrasound waveforms, overlap with a frequency range where optimal energy gains are achieved between transcranial transmission and brain absorption of ultrasound - which allows the ultrasound to penetrate bone and yet prevent damage to the soft tissues. Their findings are supported by other studies examining the potential of high-intensity focused ultrasound for ablating brain tissues, where it was shown that low-frequency ultrasound could be focused through human skulls."

I doubt that low frequency ultrasound is dangerous, some people already use it with their electric toothbrushes.

Ultrasound is just sound that is higher in frequency than what the human ear can hear.

Dogs, cats and other animals can hear ultrasound.

I realize all these things, I just don't like screwing around with things I don't fully understand. And I'm not talking about soft tissue, more about things like brainwave entrainment and what exactly you're doing to your brain. Since I'd have no idea what I'd be doing, I don't like the idea of arbitrarily using things to mess with it

I read the study, and it stated that the feasibility of in vivo usage of LILFU as a therapeutic tool is yet to be proven. It seems like they tested a variety of tissues in vitro, and noticed ion/voltage modulation, citing studies that showed ultrasound can be focused beyond the skull, but had not actually tested this technique on human subjects (understandably).

Things may begin to flower in the coming years, however. I've always wanted to look into dream-induction via neurological modulation, but am finding myself limited by economic concerns (the darn economy doesn't appreciate science as much as it used to ).

This is what im thinking, the reason where not lucid duing dreams is because the dorsolateral prefrontal cortex is deactivated during dreams.

The dorsolateral prefrontal cortex is located behind your forehead and its role is sustaining attention and working memory and consciousness



If i can find some way to have low intensity low frequency Ultrasound (LILFU) on my forehead while im dreaming. This could possibly become a huge breakthrough in Lucid dream Tech if it works.

But as you pointed out, i lack the resources, by any chance do you know where I could possibly find/buy an Ultrasound thing?

Well the actual study is here:
http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0003511

It states the researchers had used "custom built PZT ultrasound transducers" with a diameter of 35mm. I've made intrasonic speakers before (20-20k Hz range) but never anything capable of MHz range. I'd imagine they use some sort of piezoelectric element (perhaps why they are referred to as PZT). They also used a function generator to create square-waves, fed into yet what I can only guess is another function generator to generate pulses (I think they mentioned pulse-length sweeps), and finally fed the resulting signal into an amplifier for the transducer.

Generally these sort of high speed function-generators and amplifiers can be pretty costly, but eBay might a good source for this type of equipment.

The following are the parts they use:

• Agilent 33220A Function Generator
• ENI 240L RF Amplifier

Also westonsci, I'm pretty sure that lucid dreaming is much more complicated matter than either having a part of the frontal cortex active or not.

And besides, you need to first have a version that can focus. In the end, if there was a certain mechanism to induce LD's, you'd need a helmet and a system that stimulates only key areas in a certain way with certain timing. That's way beyond. Don't hold your breath.
