Drowsiness

[Nicole L Simone]

Hi!!

I need to devise a device to that will prevent a tired driver from 
getting into an accident.  I was wondering if anyone in neurophysioology 
could explain to me the mechanics behind the eye and what happens when a 
person is drowsy.  Does the movement of the eyelids change and can you 
detect this with EMG, ECG etc.

Thanks in advance for your help!
