Biological rhythms RESEARCH

1. Sleep walking: insufficient GABA, examined motor excitability in adults, sleep walkers showed signs of immaturity (7)
4. Infradian rhythms: applied armpit pheromones on to a group of sexually inactive women. 4/5 women's periods synched to the donors. (7, 2, 2)
5. Jet lag: adjustment is faster for westbound flights than eastbound (5, 2, 2)
7. Function of sleep: protection from harm! (6)

2. Circadian rhythms:spent 6 months in a cave, his sleep wake cycle extended to 25 hours (6)
3. Marathon runners slept 1 and 1/2 hours longer for 2 nights after their marathon, 45% sws compared to 25% (8)
6. Jet lag: 40 flight attendants on a 4 day flight across 10 time zones. Sleepiness, temp, melatonin and cognitive measured. Sleepier, desychronised temp and melatonin, cog decreased. (5, 2, 2)
8. Sleep walking: 19Mz and 14Dz twins, concordance rate of 47% in Mz and 7% in Dz (6)
9. Circadian rhythms: blind from birth, had a circadian rhythm of 24.9 hours despite exogenous zeitgebers like social cues (5, 2, 2)
10. Function of sleep: Restoration theory! REM restores brain function by replenishing neurotransmitters and NREM restores bodily function (6)
