Sampling of the EEG is done by the amplifier with 5000Hz fixed and either 1000Hz anti aliasing filter (normal) or 250Hz anti aliasing filter (MRI only!). Downsampling can be done realtime on the computer to 200, 250, 500, 1000, 2500 or 5000. An appropriate anti-aliasing filter should be selected for that as well, depending on the downsampling frequency.

At the default sampling rate of 500Hz, use a cutoff frequency of 200Hz.

At the default sampling rate of 500Hz, use a cutoff frequency not higher than 200Hz.

Skin impedance should be kept low, e.g. below 3kΩ. We are currently looking into the possibility of running experiments with high skin impedance.
