Each day for two weeks, Bennett would don a headband equipped with moistened sponges and attached to what she called a “big cellphone”—a tDCS stimulator. When she was ready to start the session, a clinician would give her a four-digit code to enter on a keypad, and the current would surge through the wires and into her brain.
Stumbled upon this device today, the Omni Stimulator, which seems to be mostly sold in Australia. That lead to this video where Brendan Morgan makes the case for the use of tDCS in the treatment of his depression. Again, I am not advocating the use of tDCS for the self-treatment of your depression. I’m simply collecting evidence, clinical and anecdotal, and making it available. That said, I know that if I myself were experiencing depression, I would be experimenting with tDCS. Especially in light of the fact that the efficacy of treatment of depression with SRRIs remains controversial, tDCS would definitely seem to be worth a try.

Featuring Swansea University researcher Claire J. Hanley @clairejhanley. Lucy Owen explores a new way of improving her memory. Will she score better at a memory test once her brain has been stimulated by electromagnetic impulses?

Market forces, the for-profit bias that imbues every aspect of health care in America, skew R&D towards solutions and products that are highly profitable. That’s one of the reasons I was so curious about tDCS. You can do it at home. It doesn’t cost a fortune. My initial curiosity was inspired by research papers that seemed to indicate the potential for cognitive enhancement, primarily memory and learning. Many papers later, I’m not so sure, but where it comes to tDCS and depression I’m much more confident. There does seem to be an overwhelming amount of both research and anecdotal evidence to support the use of tDCS in depression. If that were better known, perhaps someone like the woman featured in this NBC news clip would have had somewhere to turn when she was denied coverage for continuing TMS treatment for depression.
For the first time, UNC School of Medicine scientists report using transcranial alternating current stimulation, or tACS, to target a specific kind of brain activity during sleep and strengthen memory in healthy people.
Memory has always fascinated me and it’s thrilling to be alive at a time when breakthroughs in our understanding of memory are happening so frequently. I had never heard of Highly Superior Autobiographical Memory before catching a recent (this will slip behind a paywall in a week or so) This American Life episode that features Jill Price discussing how having the extremely rare condition, HSAM for short, has left her ruminating over her husbands passing for years. (More about Jill Price from 60 Minutes Australia here).
As someone who has journaled for most of my adult life the idea of being able to recall every single day in vivid detail seemed thrilling and I wondered if Jill Price’s experience was the norm among people with HSAM. That led to these 60 Minute pieces. The first two are from 2010.
After the show aired, hundreds of people contacted Dr. James McGaugh including the family of 10 year old Jake Hausler who also has HSAM. Scientists at Washington University are working with Jake to try to understand how it’s done.
And finally, ‘Memory Hackers’ from NOVA, has an update on the Jake Hausler research, and also delves into a wide variety of cutting edge memory research.
TechKnow: How do you plan on measuring your progress with the tDCS headset?
Erica: So I’m using a brain training game called Dual N-Back. So far I’ve tracked my progress with the game without using the tDCS, and I plan to use tDCS, and then practice the game and see how far I can get.
TechKnow: Are you going to record this information? Do you plan on making it available to other people?
Erica: I plan to track the amount of time I’m spending using tDCS and how well I’m performing in the game to see what is correlated.
