Controlled by a tear drop shaped area in the hypothalamus called The Suprachiasmatic Nucleus (SCN) All other clocks take their cue from SCN. The SCN itself is kept in synch with day-night patterns by a hormone ‘Melatonin’ secreted by the Pineal gland. Insomnia is correlated with and has been treated with low Melatonin levels • Way to test these cycles: Free running experiments. Here you very carefully remove people
