Electrode Placement for Alpha Activity Detection as per 10-20

HST20 · December 2015

Hi,

I am a newbie to BCI.

I would like to know best electrode placement for single channel EEG with 3 electrodes (1 ref, 1 ch, 1 drl) to detect alpha activity.

Please suggest a best non hairy site for electrode placement.

I tried Fp1(ref), Fp2 (Ch) and back of earlobe for DRL, i could not able to detect the alpha activity. signals are full of noise.

I could not able to differentiate eye open signals with eye closed signals after filtering 0.5 - 45 Hz & FFT.

Similarly, please suggest me best electrode placement for 4 channel (6 electrodes, 4 Ch, 1 Ref, 1 DRL) for SSVEP detection.

This is covered in the tutorial docs,

http://docs.openbci.com/tutorials/01-GettingStarted#getting-started-w-openbci-v-connect-yourself-to-openbci-3-connect-your-electrodes-to-your-head-and-body

Use O1 as suggested.

Use the search box (lower right) to read some of the ssvep posts. Especially checkout Chip's blog.
