transcranial or intracranial direct current stimulation tDCS

To all experimenters: the flash do nothing, is used as a placebo in the studies; to get the effect you must apply the current for minutes (15-20) every day for a week or so. For safety reasons limit the current at least with a transistor (constant current generator). Wet the electrodes with saltwater (or special gel) or you will get nasty burns on the skin (painless but ugly to see for weeks, imagine how I know it...). Check polarity twice to be sure.

wait so is this safe or what?
i wanna try it but not if its dangerous haha.

well, according to the doctors at UCLA performing the study, the current is so low it barely penetrates the cranium. however, the device they use has a limiter for the amount of current in the circuit. the initial point where you make contact, there is a surge of current. the current is sooo low .... hundreds of thousandths of that of ECT or Electro Convulsive Therapy. i cant say what is ok for you to do... but i know that it is such a small amount of current that it most likely has no effect!

unbelievable how some people make comments and do experiments with a project they don't know anything about it
first of all you always has to be sure that that the maximal 3 ma current never want to be exceeded by a 9 volt battery
just putting a 9 volt without a current regulator
on your head can be very bad for the 100 billion
neurons in your motor and frontal cortex
why don't you all first analyzed this great device first

the current involved is so low it can barely make it through the cranium! it just traverses the skin of the forehead, creating a tingling sensation. i think drinking a few beers should take care of the side effects! thank you for you comment and suggestion. it is true that one should research and learn how to properly electrocute their brains. thank you and have a great day!!

@upawko
Indeed 9 Volt is completely retarded. The general intensity is 1 V and occasionally you can use 2V if you want to stimulate deeper structures such as the motor cortex zone of the leg. 3 Volts is not done and 9 Volts.. I can't believe how people experiment like this
People can't get less scientific than this

did you use a car sponge?

it was a big yellow sponge. it was a fun experiment... but it has little if no effect. thanks for watching!

i think you forgot to add some resistors, that probably why you felt the stinging sensations.

true, the anode (+) has to be on the left hemisphere and the cathode (-) has to be on the right hemisphere.

Reason being is that the left DLPFC is responsible for being happy and the right DLPFC is responsible for being sad.

People who suffer from depression have an underactive left DLPFC
