Hi, I wonder what type of EEG cap do you use/recommend for ERP research, in order to obtain better impedance, but still to be able to get an acceptable time btw cap installing and signal recording? Thank you!
Dear Gabriela Marcu,
I will always suggest using wet-EEG or semi-dry systems, as they can improve the conductivity between the sensor and the scalp. An example of these systems:
1- ANT Neuro
2- Brain Products ActiCHamp
3- BioSemi
Hi Gabriela Marcu,
If you are planning to record from a low-density EEG cap (e.g., 32 electrodes max), I would strongly recommend active (pre-amplified) wet electrodes for recording relatively noise-free signals even in face of rather high impedance (up to 50 kOhms, Article High and dry? Comparing active dry EEG electrodes to active ...
). For this sort of settings, I would suggest BrainProducts actiCap. In my experience, the set up time was ~20-30 min for having impedance < 5 kOhms at each electrode.Best,
Thomas
