Research Methodology & Safety
Hi all,
I am new to this, and think amazing things can be done with this platform. I wanted to ask about your experience and know-how regarding the following:
1. What is the best and safest method to clean the dry electrodes between subjects in the study? (I was thinking - a toothbrush with 70% alcohol - to gently scrub and let alcohol evaporate...)
2. I need to register this device for approval by my local ministry of health (Israel).. So I can use it on subjects in a clinic. Does any of you have similar experience?
3. For the "Methods" section... Is there a pre-made piece of text you are using regarding the Cyton, Daisy and Ultracortex devices, or better yet, a citation I can use when I do the write-up? something official by OpenBCI team that I can also use for internal research comity approval?
4. I want to use a longitudinal bi-polar montage. For this I need a bunch of "Y" cables to connect the electrodes in a serial fashion to the positive & negative pins of the boards, so they form a bipolar chain with each electrode serving (except for the "end-chain" ones) as the negative of one channel and positive of the other... I don't want to make those myself (fearing clumsiness). Do you know where I can get a bunch of Y with one male and 2 female ends?
5. Also, I have a surge of rhythmic artifact on 50Hz and 25Hz ± I can't get rid of... Any idea where they come from? (yes, I am wearing the Ultracortex and I am not touching any surface that has a device connected to the grid [50Hz in israel]).
This is the beginning, many more questions to follow, Thank you all in advance,
SA
