Recording EEG and EP data

Recording evoked potentials (EPs), electroencephalogram (EEG) signals and polysomnographic biosignals requires particular attention with respect to amplification, filtering, and data handling. The present paper is aimed at providing a short overview of the fundamentals on recording techniques and the basics on biosignal processing methods used in EEG studies. It also examines the aspects associated with the reproducibility of EEG measurements, as well as the recording duration by Pharmaco-EEG (PEEG) studies.
