In selecting components for an EEG development kit, I'm wondering if certain types of electrodes capture signals better in the presence of (a small amount of) head hair?
For instance options include:
- Gold and silver cup electrodes*
- Spider electrodes**
- Webb electrodes***
- Flat electrodes
and many others. My intuition is that the Spider or Webb designs might be better because hair could go through the gaps, but that's just a guess.
