I invented, published and made open source a single EEG channel sleep/wake metric. It is called z-ratio. It has been peer reviewed and published in SLEEP, and as well the AASM has kept in the loop of possible new methods for future sleep/wake automation.
IT DOES NOT STAGE SLEEP, it provides a METRIC to gauge the relative contribution of slow to fast EEG within a single channel of EEG initially in 2 seond epochs, now down to 1 second epochs. First published in 1990.
The bibliography compilation of publications can be found here: www.z-eeg.com

The foundational basis was also recently corroborated by a study out of Boston's Mass General: http://journals.plos.org/ploscompbiol/article/asset?id=10.1371/journal.pcbi.1003866.PDF
Feel free to let me know how I can help.

ADMINS: I have applied for download rights, but have not heard back. What else do I need to do to be able to download the EDFs and start using them to investigate z-ratio on this open source of cases?
By the way, Teuniz has included z-ratio in his Open Sourced EDF browser http://www.teuniz.net/edfbrowser/
