Welcome to the ZZZratio Web site. Thanks for dropping in to learn about Z-Ratio.

Z-Ratio is my offering to the Sleep field. Availing all, a unified, standardized, reproducible, understandable, workable, transparent, intutitve Sleep/Wake metric. A possible foundation upon which to further the sleep/wake experimentation paradigm for the future of the sleep/wake circadian rhythm field.
Feel free to browse around. If you have comments or questions please drop me a line at info@claudealbertario.info.

Z-Ratio is part of Gnu-Sleep Network, where all work regarding sleep, is open sourced. I know that GNU is really a Linux based group, but I liked the name of “New Sleep” and the association with the open source movement.
Why Open Source Software or Free Software
If we were to wait for manufacturers of sleep systems to give us a standardized, unitary measure of sleep/wake, we would be waiting forever. Because, the reality in business is that if someone makes it, then no one else can use it. If the field demands the ubiquitous use of a free algorithm, then the manufacturer’s cost is only for the programming to interface it into their system. Then, the field has a basis to compare sleep/wake EEG, lab to lab, patient to patient, study to study. The benefits of an open source movement in Sleep far out ways any drawbacks.

Thanks for visiting,
