Somewhere in the course of running down the Rabbit Hole this morning, I found myself thinking, ‘Wait, this feels familiar.’ Then I remembered where I’d seen Jamie Tyler recently- on the About page for Thync! He’s the CSO and Founder! Exciting to think about what may evolve from Thync based on the links below. We do know that Thync’s first product, now in Alpha will be tDCS based.
Are you ready for Digital Heroin?

“Other advantages of ultrasound are that it can be focused through the skull to any discrete region of the brain with millimeter accuracy.”
Tyler Lab of Neuroscience and Neurotechnology
Tyler has so far investigated whether ultrasound stimulation could stop epileptic seizures, in which lots of brain regions start firing in synchrony. In one of their first experiments along these lines,Tyler’s team induced seizures in mice before applying ultrasound pulses to their skulls. The sound waves broke up the synchronous firing, ending the seizure. He has high hopes that the technique could be used to treat people with head injuries, who often have seizures. “What if you could develop a device that was an automatic external defibrillator, except for the brain, to treat brain injury?” says Tyler. “That’s my vision.”
The work has inspired Stuart Hameroff to test the technique on himself. An anaesthesiologist and consciousness researcher at the University of Arizona Health Sciences Center in Tucson, Hameroff first suggested to a colleague that they try the therapy to treat chronic pain. The colleague agreed, on one condition. “He looked at me and said, ‘you have a nice shaped head, why don’t we try it on you’,” says Hameroff.
So they did. They applied ultrasound to Hameroff’s temple for 15seconds. Nothing happened immediately. “But about a minute later, I started to get a buzz, like I had a martini, and felt really good for about 2 hours.”

Are there results? When can we buy the “Think Cap” as in “Gyro Gearloose” (Disney), “Doc Brown” (Back to Future) and Fourth Season “The Flash” (DC Comics) :-)?
Is this “DIY”? Will we receive data for replica?
Do you use “CMUTs”? Where can we buy these “CMUTs” emitters?
How will it be possible to reach every part of the brain exactly? You can focus the depth of a single CMUT?
But you have to make the individual CMUT mechanically adjustable (on the head surface)?
If so, how many CMUT should such a part usefully have?
4, 8, 12, 16, …, 32 … channels?
Or you have to use a lot of strong little CMUT spread all over the cap.
Same technology ?:
I think we’re a long way off DIY for focused ultrasound. Jamie left Thync a few years ago and is back running his own lab. https://sites.google.com/view/tylerlab/ His most recent paper is ‘Ultrasonic modulation of neural circuit activity’ https://www.sciencedirect.com/science/article/pii/S0959438817302015 One way it may be possible to reach specific parts of the brain with ultrasound, is by combining two frequencies, from different directions. Where exactly the two frequencies meet another frequency is created and that frequency does the stimulation. But that’s a layman’s perspective from reading through a handful of papers. No I think haptics, though it uses ultrasound, is unrelated to brains stim. Thanks for stopping by. John
