    What do you already know?

    Circadian rhythms govern behaviour over roughly 24 hours and are seen in many different species.

    In humans, one example is the sleep-wake cycle that is governed by the SCN which causes melanin production when it's dark, making us sleep.



    What species are you looking at? How much detail do you need?

    I have only had two lessons haha! I know the basics about the rhythm and then know studies such as siffre and morgan/silver etc i know about the sleep wake cycle and that the suprachiasmatic nucleus sends a message to the pineal glad to produce melatonin etcetc and that exogenous zeitgebers help to keep this cycle on track e.g. light and dark triggers the cycle.

    (obviously that is terribly explained but just to outline what i do know - it's more how i can structure it!!)

    I just have no idea how to start it i.e. do i explain what a circadian rhythm IS, or do i go straight into explaining how the exogenous zeitgebers and endogenous pacemaker works together i just don't know haha!

    I'd definitely start with what a CR is as youll be referrring to it the whole time.

    The go onto explaining EZ and EP and then their interactions.

    That's just me though!
