This night I spent equipped with:
* EEG for brain activity
* EMG for muscle action around my eyes, around my mouth and in my legs
* Blood oxygen saturation meter on a finger
* Thermistor in front of my mouth, to measure breaths
* Air pressure meter up my nose, to distinguish mouth breathing from nose breathing
* Chest bands to measure breathing activity at all
I had a second pony tail made out of cables!
