A method and system for sleep stage determination is disclosed comprising: acquiring EEG data from two or more EEG electrodes of an electrode arrangement, wherein the EEG data is divided into one or more epochs; detecting graphoelements from the EEG data for each epoch using a graphoelement detector; calculating a differential entropy from the EEG data for each epoch in an entropy module; and assigning a sleep stage to each epoch based on the calculated differential entropy and the detected graphoelements in a classifier module. This new method and system of sleep staging is potentially suited for, but not limited to, unattended sleep diagnostic scenarios.
