This was announced a few days ago and to be honest, I wasn’t sure what to make of it… a battery-looking EEG thing. Certainly I’m not a ‘Dev’ and so I left it to those who are to parse the details, still… Ah, yes, further details arrived today via email I’m happy to share with you (below). I do get the feeling this will make EEG devs excited.
Thanks for all your feedback and questions about the focus EEG. A common question has been what exactly is included (see below) and is it everything required (yes).
Included in EEG Dev Kit
foc.us EEG 24-bit 8-channel EEG with tES & Wi-Fi
8 active dry electrodes for EEG, plus bias & reference electrodes
2 active bio-potential electrodes for ECG, EOG, EMG or EKG
2 wet tES electrodes for tDCS, tACS, tPCS or tRNS
10-20 placement cap
Mains power adapter for recharging
Raw data access
Next week we will provide more details on the software and SDK for EEG processing.
P.S. The first 100 66 are available at only $999 $499 – half price!
What I’m excited about is the Focus EEG headset, but a recent tweet exchange indicates we’re a good year away from release.

Analysing these high-standard studies revealed that tDCS seems to reliably improve the symptoms of depression, addiction and craving, and fibromyalgia. It also uncovered that the technique does not work for tinnitus, and that the evidence for using tDCS for stroke rehabilitation was not as strong as many had thought.
The paper, Gamma frequency entrainment attenuates amyloid load and modifies microglia makes clear that the light-flickering affected the visual cortex, which makes sense, as the light reaches the brain through the eyes. But wait, thinks I, what about tACS (transcranial Alternating Current Stimulation)… haven’t I seen numerous papers implying the ability to ‘entrain’ brain waves with tACS? What if you could increase 40hz Gamma in other parts of the brain? (Google Scholar Search: transcranial alternating, entrain, gamma)
But then I discovered that Radiolab just covered this exact story and it’s totally amazing! Really a must listen. So fun to hear the researcher’s amazement at this accidental (sort of) discovery!
So what’s with the photo of the Foc.us v2 device set up for a 40hz tACS session? Just that…

Hi John, our research centre (CIBF via The Brain Dialogue) is doing a project involving home users of brain stimulation, the details of which can be found here http://www.cibf.edu.au/unintended-consequences-research-project… We’re currently conducting a survey on how these home users find and use scientific literature. If it’s appropriate for your website, we would love if you could post about the survey as we want a broad range of home users to participate and DIYtDCS keeps cropping up in the conversations we have about home use. The survey can be found here https://www.surveymonkey.com/r/unintendedconsequences Please let me know if you have any questions or want more info about the project; you can also reach me via Twitter @ElizabethJPaton
Although the home use of tDCS is often referred to as a novel phenomenon, in reality the late nineteenth and early twentieth century saw a proliferation of electrical stimulation devices for home use.
In particular, the use of a portable electrotherapy device known as the “medical battery” bears a number of striking similarities to the modern-day use of tDCS.
Many features related to the home use tDCS—a do-it-yourself movement, anti-medical establishment themes, conflicts between lay and professional usage—are a repetition of themes that occurred a century ago with regard to the medical battery.
A number of features seem to be unique to the present, such as the dominant discourse about risk and safety, the division between cranial and non-cranial stimulation, and utilization for cognitive enhancement purposes.
Viewed in historical context, the contemporary use of electrical stimulation at home is not unusual, but rather the latest wave in a series of ongoing attempts by lay individuals to utilize electricity for therapeutic purposes.
An email from Michelle Pearson at the NIH (because I had signed up for the online version of the workshop) alerted me today to a trove of TES (Transcranial Electric Stimulation) info being made available to us. Presenter slides (in PDF form) from the workshop were available for download. Because the download process was pretty wonky, involving many clicks and declined logins to Dropbox I thought to make them available here as well.
Can a little electrical stimulation help people learn quicker? And how would technology that does this be used? And why would you want to use this over medicines?
Professor Roi Cohen Kadosh describes a phenomena that they’ve noticed where giving people a little electrical stimulation to the scalp appears to help people learn things quicker; and rather than using this to make super-geniuses, could this be used to help people with learning difficulties? Roi discusses how it might work, and discussed the moral and ethical implications of such a technology. From Oxford Sparks.

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.

We developed a cellular brain stimulation device as part of our ELEC5622 Sensors, Signals & Health assessment at the University of Sydney. The technique, known as transcranial direct current stimulation (tDCS), uses weak electrical currents to modulate ongoing brain activity, and is a promising treatment for a range of neurological and psychiatric diseases. As the feasibility of administering tDCS at home has recently become an emerging area of research, there is a substantial need for a tDCS device which send data to the clinician in real time.

Unlike commercial brain training products, which only improve performance on the skills involved, musical training has what psychologists refer to as transfer effects – in other words, learning to play a musical instrument seems to have a far broader effect on the brain and mental function, and improves other abilities that are seemingly unrelated.
“Music reaches parts of the brain that other things can’t,” says Loveday. “It’s a strong cognitive stimulus that grows the brain in a way that nothing else does, and the evidence that musical training enhances things like working memory and language is very robust.”
