The multiple sleep latency test (MSLT) and the maintenance of wakefulness test (MWT)use objective measures to quantify sleepiness. The Oxford SLEep Resistance (OSLER) test, which is a simplified variation of the MWT, is another objective that can be used to indirectly quantify sleepiness. How do...
This means sleep latency is defined as the number of epochs preceding the first uninterrupted ˜16 s of an EEG depicting activity consistent with sleep. An individual could conceivably achieve this 16-s threshold within 2 min, wake up, and not return for another 2 h (SOL = 2 min). ...
