Recording EOG signals with actiCHamp – active or passive electrodes?

The artifacts produced by eye movements and blinks are problematic for the EEG researcher and can have a negative impact on results. Advanced algorithms (e.g. Ocular Correction ICA) can be very effective in correcting the ocular related artifacts, however in some cases a dedicated ocular channel is required. Here, we will describe various approaches on how to use an actiCHamp amplifier to record an Electrooculogram (EOG).
