[Eeglablist] LPP and skin potentials

[Makoto Miyakoshi]

Dear Sahar,

To control skin potential you need to control room temperature and
moisture. I'm not sure if it is a common practice in recording EEG.

Our group uses relatively high cutoff frequency for highpass filter
(around 1 Hz) because suppressing the skin potential improves ICA
performance.
