TRANSCRIPT
Disrupting Biological Rhythms AO1
• Write down all you know about the disruption of biological rhythms
• Add your name and then swap papers
• Mark the work based on the following success criteria
Success criteria = Max 80 marks
Mentions jet lag = 5 pointsExplains jet lag = 10 points
Mentions shift work = 5 pointsExplains shift work = 10 points
Mentions DSPS = 5 pointsExplains DSPS = 10 pointsKey terms = 5 points each
(Circadian rhythm, oscillators, SCN, melatonin, phase delay, phase advance, desynchronisation)
• Excellent = 50-80 points
• Good = 30-49 points
• Average = 15-29 points
• Needs work = 0-14 points
Objectives
• The Big Question….– Discuss the disruption of biological rhythms (8+16)
• AO1 topics– Jet Lag– Shift work– Delayed Sleep Phase Syndrome
• What do think you need to be able to do for the AO1 part of this question?
Disruption of biological rhythms
• So far we have found out that biological rhythms are controlled by endogenous pacemakers or oscillators.
• Some of these oscillators can easily be reset by exogenous zeitgebers, whereas others are more resistant.
• This means that sometimes, our oscillators can become desynchronised – out of time with each other.
How are our circadian rhythms disrupted?
• Our circadian rhythms can be subject to;– Phase advance – e.g. having to get up earlier than
usual – Phase delay – e.g. going to bed later than usual
• Which do you think is easiest to deal with?
• Why?
What are the consequences of disrupting biological rhythms?
• Today, you will be looking at three of these:– Jet Lag– Shift Work– Delayed Sleep Phase Syndrome
• You will be responsible for finding out about the effects of one disruption, and teaching this to others.
• You need to fill in your sheets as you go along

How did you do?
Consider your progress…
• How do your results compare?
• If you made progress from last time, how did you do it?
• If you did not make progress from last time, what could you do differently next time?
The Big question…
Discuss the disruption of biological rhythms (8+16)
• You have already completed the AO1 for this
• Today you need to gather the AO2
Disrupting biological rhythms AO2
• Using your hand outs and planning grids you should work in pairs to get the AO2 for disrupting biological rhythms together.
• Remember to work on tying up those implications
• These need to be linked to the question and the point in your MRI paragraph
