NEWS FROM THE FUTURE – Transcranial direct current stimulation (tDCS) kits. NEWS FROM THE FUTURE – Transcranial direct current stimulation (tDCS) kits… via Joel. tDCS is one of the coolest pieces of health/ self improvement technology available today.
The US Army and DARPA both currently use tDCS devices to train snipers and drone pilots, and have recorded 2.5x increases in learning rates. This incredible phenomenon is achieved through a very simple device called a tDCS machine.Today if you want to buy a tDCS machine it’s nearly impossible to find one for less than $600, and you are typically required to have a prescription to order one.
We wanted a simpler cheaper option. So we made one. Looks like it’s not that hard to make your own… Phillip Torrone Editor at large – Make magazine. Related. tDCS thread - Brain Health. Where am I going wrong in my calculations below?
Take a voltmeter and set it on resistance (Ohms), put salty water on your fingers, and then hold the tips of the two probes in the wet finger tips of each hand. What do you read? When I do this experiment, my meter reads a resistance of about one hundred thousand (100,000) ohms +/- 100%. That seems to be a typical resistance across any two points on the human body. So if you want to create a current across two points on your body, then you can use Ohms Law to find out how much voltage to use: V(volts) = I(amps) * R(ohms) R = 100,000 ohms I = 2 milliamps = 0.002 amps (according to my reading of the tDCS literature) Solving: V = 100,000 * 0.002 = 200 volts (Better check my math) So a 9 volt battery is not going to cut it. Looks like you will need a lot bigger battery! Perhaps this higher voltage required explains why the the research systems are so expensive.
Informed Consent - tDCS video# Transcranial DC stimulation (tDCS) improves voluntary modulation of mu-rhythm used for brain-machine interface (BMI) control. The development of non-invasive and invasive BMI systems that translate electric or metabolic brain signals into control commands of external devices has experienced an impressive growth over the last years.
They usually rely on the subjects' ability to control neural activity. The more rapid and accurate the control of such activity, the more effective BMI systems are. However, learning to control such activity often requires extensive training and, thus, it would be desirable to find strategies to facilitate learning. In the motor domain, learning can be improved through designing practice protocols and/or by combining practice with stimulation of the central nervous system in the form of transcranial magnetic (TMS) or direct current stimulation (tDCS) that can facilitate learning effects.
It was shown that these stimulation techniques can influence brain rhythms. Preliminary data support this hypothesis.
