Transcranial Direct Current Stimulation ( tDCS ) has come a long way in just a few years. This incredible technology can relieve depression, improve memory, speed learning, and more and is slowly moving toward main-stream as new research, products, and government approvals come along. It’s been the darling of university research centers since Scientific American published a ground-breaking article about tDCS in 2011 ( see https://www.scientificamerican.com/article/amping-up-brain-function/ )
Now foc.us (www.foc.us) has another product in their portfolio of brain stimulation and EEG related products – the Go Flow 4 – which is available in the US from http://www.caputron.com for $244. This complete kit includes a versatile, compact tDCS device, battery, electrodes, wires, headband and basic instructions.
Here’s How It Works
The Go Flow 4 tDCS device passes an extremely small direct current through your brain via specific locations on your scalp in order to enhance or reduce a particular kind of brain activity. It is thought that the excitation level of various brain cells is modified by the current and can result in reduction or elimination of depression symptoms, improved memory, quicker learning (including physical task learning), improved sleep, and more. Electrodes must be placed correctly and 20 minute sessions must be repeated daily for a number of days in order to receive the full benefit of tDCS. tDCS is used by the US military, various mental health professionals, and pioneering individuals around the world.
To use the Go Flow 4 you follow some simple steps:
- Attach the battery to the Go Flow 4 device
- Place electrodes in the headband at the desired button-hole locations and moisten the electrode sponges with tap water or saline water.
- Set the current and duration for the session using the rocker switch on the Go Flow 4
- Place the headband on you head and position as desired. Start the tDCS session and monitor current and time remaining using the LED lights on the tDCS device
More detailed instructions are included with the Go Flow 4 and should be read carefully before use.
While most tDCS scenarios (called “montages”) use two electrodes and a current of two milliamps or less, the Go Flow 4 has some advanced capabilities that permit the use of four electrodes simultaneously, a current of up to four milliamps, and a special mode call slow oscillating tDCS (sotDCS.) More on these in my next post.
Using the Go Flow 4
My experience with the Go Flow 4 is very positive. It is easy to use, very convenient, great for portable and travel use, and delivers predictable and reliable tDCS sessions. I love that you no longer need to disconnect the battery after use as a prior version of the Go Flow required.
Before you buy this or any tDCS device, do your homework. tDCS is not for everyone. Read about tDCS (google search at least) and decide if it is right for you. I can also suggest you visit:
