1. Who found that daytime sleep is typically between 1 & 2 hours shorter than a nocturnal sleep period and that REM in particular is affected? (6, 3, 9)
4. Who calculated that it's the equivalent to one day to adjust to each hour of time change? (6, 2, 2)
5. --------- has been put forward as a 'miracle' cure for shift lag and jet lag, which makes sense as it's the natural hormone that induces sleep. (9)

8. The effects of circadian disruption ---- between individuals. (4)

10. Who were able to entrain circadian rhythms to longer than 24 hours just by using bright light pulses - modulated light exposure (MLE)? (8, 2, 2)
