tDCS

tDCS is the most basic form of electrical brain stimulation. A fixed current for a fixed duration through a region of the brain.

so-tDCS

slow oscillating tDCS adds a rise and fall to the current at 0.75Hz. See the Go Flow 4 image above which shows so-tDCS in action.

tACS

Alternating Current is distinct from tDCS because the current changes direction. So the anode becomes the cathode and vice versa.

tRCS

Rippled Current stimulation, also termed α-tACS uses frequencies in the alpha wave band to entrain your brain waves.






tRNS

Random Noise stimulation. Stimulating the brain with a random current and a random frequency.

tPCS

Pulsed Current

EEG

EEG measures the electrical activity of the brain.

fNIRS

fNIRS is a technology to measure blood usage in the brain.

What people say about focus:

It's no secret that I'm a bit of a fan of foc.us. The small London based DIY company has been on a serious innovation binge since they entered the market with the foc.us V1 - which was by far the most versatile tDCS* device in its time. Later foc.us released the V2 which is still one of the most capable brain stimulation devices on the market (not just tDCS.) Late last year, foc.us introduced the Go Flow - a simple, very portable, tDCS device for a very low price. It has evolved into a complete kit that the company is calling the Go Flow Pro - it includes all you need to have a very capable tDCS device that is simple to operate - and only $99 complete. Dr Brent Williams


The Foc.us device, which was released in the summer of 2013, was arguably the first true direct-to-consumer tDCS device. With its sleek, ready-to-wear headset design, it looked more like Google Glass than a cobbled-together DIY device. Anna Wexler
