The focus of the second day of the workshop will be non-invasive brain stimulation medical devices, which are medical devices that are intended to improve, affect, or otherwise modify the cognitive function of a normal individual (i.e., without a treatment objective) by means of non-invasive electrical or electromagnetic stimulation to the head. The purpose of this workshop is to obtain public input and feedback on scientific, clinical, and regulatory considerations associated with medical devices for assessing and influencing cognitive function.
An overwhelming amount of tDCS-related information is about to descend upon us.
Neuroscience 2015 will take place October 17-21 at McCormick Place in Chicago. Join more than 30,000 colleagues from more than 80 countries at the world’s largest marketplace of ideas and tools for global neuroscience.
Here’s a small sample of some of the tDCS-related presentations/abstracts that caught my eye. (Unfortunately I can’t link to my search results so I also scraped the page so you can see for yourself here.)
Revisiting this post from a few months ago because as I slowly wade through these state-of-the-art brain stimulation presentations from the leading scientists in the field, I’m discovering a lot of new information that is not generally known or being discussed. For example, in this talk ‘BrainSTIM2015 – Physiology and functional effects of tDCS and related techniques’, Michael Nitsche explores why 1mA may be a better dosage choice and also how a second session of tDCS 30 minutes after the first may lead to increased plasticity effects.
Vince Clark has just published video presentations from the recent BrainSTIM conference.
This is a real treasure trove of state-of-the-art tDCS and brain stimulation information.
Presenters: Vince Clark, Giulio Ruffini, Marom Bikson, Peter Bandettini, Michael Nitsche, Katie Witkiewitz, Peter Fox, Luke Torre-Healy, Erika Ross, Mayank Jog, Abbas Babajani-Feremi, Alexander Opitz, Mark Lowe, Hiroyuki Oya, Felipe Salinas, Shalini Narayana, Branislava Curcic-Blake, Franca Tecchio, Yuranny Cabral-Calderin. https://www.youtube.com/channel/UCJXWh-KAWQdAYXZAMeH4SCg
Dr. Giulio Ruffini, “Transcranial Current Stimulation: Going Multifocal”
“…I will describe a new class of devices using multi electrode montages and small, EEG-compatible electrodes, complemented by advanced biophysical models.”
Dr. Marom Bikson, “Targeting transcranial Electrical Stimulation using EEG: The scalp space approach”
“…Next, how to optimize tES based on either evoked or spontaneous EEG recording is discussed including a novel “scalp space” approach which requires no source localization and no computational modeling.”
I see also that the The Neuroelectrics Team will be demonstrating their “latest wireless EEG (Enobio) and tCS (StarStim) technology as well as our latest StarStim Research Home Kit.

How far would you go to improve your focus, memory, or even learning ability? Would you be willing to strap on headgear that delivers electrical shocks to targeted areas of your brain? You may soon have that option. It’s called transcranial direct current stimulation, and while variations of the technique are already known to help depression patients, it’s currently being tested on soldiers, and used by gamers, students, and others looking for a cognitive edge. Does it work? Can carefully directed electrical stimulation improve cognitive function? What are potential long-term effects? And how should it be regulated?
BrainSTIM 2015 will be the first ever meeting focused on the combination of brain imaging and stimulation. The meeting will have keynote lectures by leaders in the fields of imaging and stimulation, talks selected from submitted abstracts, educational sessions on integrated brain stimulation and imaging, poster sessions and other opportunities to network. The meeting is designed to inform and educate all who are interested in these topics, from novices to experts. [Get more info]
To clarify the takeaway message: we weren’t actually training fluid intelligence. Fluid intelligence has been shown to rely on fundamental cognitive abilities like working memory and attention, and the games were designed to train those underlying abilities. Training on fluid intelligence tasks would be like teaching to the test.
In a talk, “Can HD-tDCS Enhance Cognitive Training”, Aldis Sipolins describes a ‘wildly ambitious’ cognitive training study called the INSIGHT Project. Funded by IARPA, the study combined rigorous exercise and HD-tDCS-enhanced cognitive training in an attempt to increase ‘fluid intelligence’. 518 subjects, half of whom underwent pre and post fMRI scanning, undertook a 16 week course of combined exercise and brain training. The results? Anodal HD-tDCS improved performance on 3 of 6 brain-training video games but had no effect on transfer, i.e. the improvements did not transfer to general intelligence. As a result tDCS will not be a part of the study moving forward.
Partnered with Aptima to create a suite of six brain-training games. Games were ‘adaptive’, i.e they increased in difficulty as the subject’s performance improved.
Montage used was 2 x 2 (4 electrodes) designed by Soterix to affect DLPFC (dorsalateral prefrontal cortex). Dosage was 2mA for 30 minutes. Training started once current ramped up.
BOMAT (bochumer matrices) test was used to determine whether enhanced game performance transferred to fluid intelligence.
A future study on the INSIGHT Project will include a Mindfulness meditation segment and include nutritional supplements (brain shake).
In a recent Reddit thread when asked what he’d do differently, Aldis Sipolins said:
1) Include a cathodal group, with the hope that it impairs performance. Vince Clark suggested that impairing performance during cognitive training may have led to greater transfer. Kind of like how strapping weights to your body when you train makes it easier to move once you take them off.
2) Include a tDCS group that doesn’t complete the exercise intervention. It’s possible that exercise masked the effects of tDCS.
An intensive two-day international meeting dedicated on the design and implementation of tDCS in clinical and research settings. Update on 2014 state-of-the-art methodology with presentations and discussions on the development of professional standards for safety, validity and reproducibility of functional outcomes in tDCS applications.
