Functional Recovery: the brains ability to adapt after damage to itself, healthy brain may take over the functions of those damaged areas
endogenous pacemakers
sleep/wake cycle
sunlight hits the optic nerve, travels to the SCN which is located in the hypothalmus and is sesntive to light, this triggers the release of cortisol and then at night the SCN tirggers the release of melatonin from the Pineal Gland
Morgan (1955) bred hamsters so that they had circadian rhythms of 20 hours rather than 24. SCN neurons from these abnormal hamsters were transplanted into the brains of normal hamsters, which subsequently displayed the same abnormal circadian rhythm of 20 hours, showing that the transplanted SCN had imposed its pattern onto the hamsters. This research demonstrates the significance of the SCN and how endogenous pacemakers are important for biological circadian rhythms.
