Not sure where to start?
Most people arrive with one of these questions. Each link goes to the guide that answers it.
Models you can operate
Set the inputs, step through the simulation, and watch a mechanism behave rather than reading a description of it. Each exhibit says plainly which parts follow from the physiology and which are assumptions laid on top.
Two processes, one sleeper
Sleepiness is not one quantity but the distance between two: a pressure that builds while you are awake, and a clock that sets how much pressure it takes to put you under. Move the bedtime, try to nap, lose a night — and watch why six in the morning feels better than four.
Open exhibitInsomnia & CBT-IWhy less time in bed produces more sleep
Ten hours in bed, five hours asleep. Set your own bedtime and wake time, watch the window shrink to fit the sleep, then step through the weeks as it grows back fifteen minutes at a time. Four steps, one bar each — built to be understood in a clinic visit.
Open exhibitSleep apneaThe airway closes, and four signals find out at different times
Between the back of the nose and the top of the larynx there is no bone holding the airway open — only muscle, and sleep turns the muscle down. Choose a mild, moderate or severe airway, set the arousal threshold, the sleep stage and which way the sleeper is lying, then watch the EEG, the airflow, the chest belt and the oximeter disagree about when the event happened — and about what it cost. Then put the CPAP mask on and watch the airway held open from the inside.
