1. A method of sleep stage determination, comprising:

  • receiving electrical potentials corresponding to biological signals from an electrode assembly positioned over a head of a patient;

    processing the biological signals to determine EEG signals, EOG signals and EMG signals;

    calculating, with a processor, a pre-score based on the EEG signals, the EOG signals and the EMG signals and a plurality of rules;

    using said processor for determining based on said plurality of rules and said pre-score whether the sleep stage can be categorized by the pre-score;

    checking whether a sleep stage has been categorized based on said pre-score using said processor; and

    when said checking step determines that the sleep stage could not be categorized based on said pre-score, determining the sleep stage based on at least one epoch.
