tDCS: We Were Stupid
- derekja 15y agoyikes, be careful! Hey, I'm curious how you plan to limit current issues through the electrode contact quality. I know when putting on EEG electrodes you can test the impedance, would something like that be needed here?
- teddyknox 15y agoI'm really glad he did that so I didn't have to. The effects sound pretty cool though.
- teddyknox 15y agoThis whole thing reminds me of Uncle Rico's time machine in Napoleon Dynamite. http://www.hulu.com/watch/8729/napoleon-dynamite-2004-the-time-machine http://www.hulu.com/watch/8729/napoleon-dynamite-2004-the-ti...
- ricksta 15y agoWhy would they put 6mA when you are suppose to send 2mA? 9v/6mA is 1500Ohms. If they added a 3k resistor in series with their setup, they would've up the total resistance to 4500Ohms, resulting in 9v/4500Ohms = 2mA of current.
- tiddchristopher 15y agoTo clarify, we measured about 8000 Ohms of resistance through the head, using our electrodes. For some reason, our measurement was off. I'm assuming it's a problem with the electrodes. To fix this issue, we'd need constant monitoring and adjustable resistance. In no way was I planning on running 6mA through my brain.
- freshhawk 15y agoI guess you're just braver than me but constant monitoring and adjustable resistance are the barest minimum features needed before I'd even consider running current through my brain.
- tanvach 15y agoWith two components you can build a variable constant current source very quickly: http://users.telenet.be/davshomepage/current-source.htm http://users.telenet.be/davshomepage/current-source.htm
