"Polysomnography is a comprehensive recording of the biophysiological changes that occur during sleep.... Polysomnography is used to diagnose, or rule out, many types of sleep disorders including narcolepsy, restless legs syndrome, REM behavior disorder, parasomnias, and sleep apnea. It is often ordered for patients with complaints of daytime fatigue or sleepiness that may be caused by interrupted sleep." (Wikipedia, http://en.wikipedia.org/wiki/Polysomnography)

- If both the ROC and LOC are placed in their recommended positions, and they occupy channels 1 and 2 respectively, they will converge when the patient is looking down.
- If the patient looks down and to the left, what type of deflection will be seen in the ROC channel?
- If the senstivity is is set to 5 µV/mm, a voltage of 50 µV will cause how much deflection?
- With a sensitivity setting of 10 µV/mm and deflection of 8 mm, what is the input voltage?
- Sensitivity is calculated by dividing the input voltage(µV) by the deflection (mm).
- It is recommended that the high-pass filter on an EEG channel be set around 35 Hz.
- In polysomnography, amplitude is typically measured in_____.
- Which is an appropriate low-pass setting for an EMG channel?
