3rd eye activation using electrical brain stimulation

Pineal gland stimulation was added to V3 in response to requests from v2 users for specific stimulation frequencies. tACS in V2 could only reach ~400Hz and the request was for 936Hz so we had to make some tweaks. But it seemed interesting so we did it.

You need to place the electrodes to try and make a path through the pineal gland but since there is no paper on this area you’re going to have to suck it and see!

Many studies stimulate below the surface and so do some commercial products e.g. Modius Health. Try some tACS through your hypothalamus and you can easily confirm it.

3rd eye activation using electrical brain stimulation? from tDCS

Every foc.us product works.

tDCS was shown to improve working memory and so we marketed that as a benefit to Gamers in our first product before consumer tDCS was a thing. Rippled current is our name for alpha-tACS if you want to check the studies. 3rd eye was added because customers asked for that frequency to try and stimulate the pineal gland but we don’t know the results yet.

Theranos raised $700m from investors and made a vapourware product. Foc.us raised $0m from investors and have developed and retailed real physical products. In our 5 year history that includes Gamer, V2, Go Flow, EEG Dev Kit, V3 and now Go Flow 4. Each years new device improves and pushes what is possible for diy stimulation. We welcome being looked into and we stand behind all our products.

Although I guess our fNIRS sensor is a little Theranosy 🙂

Go Flow 4 Display showing active so-tDCS session.

Focus Go Flow 4 includes a sotDCS mode.

To turn on Go Flow in sotDCS mode – press the red button twice – short, then long. You will see a red rainbow effect to confirm sotDCCS mode.

  1. Set your current level & 2) set your duration – the same as tDCS mode.

But now, instead of constant current, it will oscillate at 0.75Hz

You can see this oscillation on the display – pictured above.

tDCS Clinical Trials

I’ve been noticing a growing number of announcements of clinical trials investigating the efficacy of transcranial Direct Current Stimulation (tDCS). Eventually, they were getting hard to ignore. So I got to wondering whether this was just me or whether there was genuinely an identifiable increase.

A lot of the trials are announced on clinicaltrials.gov, so that’s the first place I looked. Here’s a graph of the number of trials that were announced each year since the inception of the site in February 2000.

So it certainly does seem that there has been a huge increase in the number of clinical tDCS trials being undertaken. These are not all medical in nature. Many published trials involve investigation of the effects of tDCS on healthy participants.

The vast majority of the clinical trials have not published results yet, but we at foc.us greatly welcome these. The scientific studies conducted in universities tend to have smaller sample sizes and, as we know, meta-analyses of these have had mixed outcome.

Clinical trials tend to have larger samples sizes so they can throw valuable light on just how effective tDCS interventions are. We’ll be following and reporting on the results as best we can.

The effects of Transcranial Alternating Current Stimulation (tACS) at Individual Alpha Peak Frequency (iAPF) on motor cortex excitability of young and elderly adults

Interesting new paper about tACS and peak alpha :



Transcranial alternating current stimulation (tACS) was shown to modulate brain oscillation, cortical excitability and behaviour. This technique allows for the direct perturbation of brain oscillation such as the EEG alpha wave (8–12 Hz). In aging, there is correlation between the decrease in alpha activity and the profound cognitive and motor impairments. Studies suggest a state-dependent effect of tACS on alpha activity: upregulation of alpha oscillations only occurs in conditions of low alpha power (e.g. in the elderly).


Remember, the foc.us v3 is the only brain stimulator that has rippled current designed to increase your peak alpha.
