More Thoughts on Thync

Just because it’s come up quite a bit lately on the tDCS subReddit , I thought to re-publish this link to a talk Jamie Tyler gave just prior to the release of their device, where he explains his understanding of what’s going on, as well as their intentions. Jamie’s intro starts at 45:46. He begins his explanation of how Thync’s device works at 52:46.

“Cognitive Enhancement by Non-invasive Brain Stimulation” with Roy H. Hamilton

An intelligent introduction to tDCS and TMS in the context of Cognitive Enhancement. Dr.  Roy Hamilton (at around 19:00 in the video, the beginning is basic intro boilerplate) discusses studies which demonstrate significant positive cognitive effects in healthy individuals. I especially liked Dr. Hamilton’s take on the concerns and potential risks of non-invasive brain stimulation which he discusses towards the end of his talk.

Marom Bikson lecture “Non-invasive brain stimulation: mechanisms, effects and opportunities”

Unfortunately, the quality of these videos is quite poor (always use a tripod, always get a direct audio feed of the lecture 😉 You can download an enhanced audio-only mp3 of the lecture here.

A Treasure Trove of Stimulating Information!

universityNMJust found this in iTunesU. Wow! You’ll recognize many of these names if you’re reading the tDCS literature. I’ve only watched the Michael Weisend talks (whom we met earlier on the blog) so far. I have a much better understanding of the difficulty of running a tDCS trial now. There’s a lot that can go wrong. If your protocols aren’t set up just right, your information might be useless. Here’s the web link iTunes Link from which you can download in iTunes. Downloads are quite slow.

Marom Bikson’s ‘tDCS State of the Art’ Lecture Now On YouTube

There’s just so much going on in tDCS right now that it’s hard to keep track. Coupled with the fact that I don’t have a Uni account that lets me access new paper (although I’ve had some help there from time to time). One of my objectives is to understand what’s going on well enough to present you with an accurate overview of what’s new. But lately research papers are coming so quickly that it’s been overwhelming.

But here’s my take-away from Marom’s lecture: Electrode placement does not necessarily correlate with current flow! At least not the way one might assume. Watch the videos to get a clear picture.

 

Juri Kropotov – Institute of the Human Brain of Russian Academy

Another significant player popped up today. Juri Kropotov (bio) Institute of the Human Brain of the Russian Academy of Sciences. You can download his 2006 Powerpoint presentation, “Transcranial Direct Current Stimulation (tDCS): a new old tool in neurotherapy” Here. You can see the Google Quick View version (and print it) here. Of special interest may be Kropotov’s use of tDCS in treating ADHD.
