Design outcomes

Primary

Measure	Time frame
Can the participants detect more alpha peaks in the power spectral density using the first derivative of the raw EEG? To measure the primary outcome parameter we present 180 power spectral density (PSD) plots of 10 sec of the raw EEG, and 180 PSD plots of the time-discrete first derivative of the EEG (diffPSD) to the members of the department of anesthesiology and ask for the presence of an alpha peak.	—

Secondary

Measure	Time frame
Does the presentation of the power spectral density of the first derivative of the EEG result in a more homogeneous evaluation? Does the number of detected peaks correlate with experience/training?	—
