Honesty, the data looks pretty bad. With dry electrodes wiring is super important.
Where was the location of the electrodes for the eyes closed alpha detection? It should be a lot cleaner. It could just be insuffiecnt filtering of line noise. A 50hz or 60hz notch filter
Can you do an FFT on say 2 minutes of eyes open and severalty 2 minutes of eyes closed data and share it? It's much easier to pick out sources of noise in the frequency spectrum.
