why is sleep important?
1. allows the body to repair itself
2. growth occurs during sleep
3. immunity is lost with sleep deprivation
4. learning, concentration and memory

how does sleep affect the prefrontal cortex?
1. prefrontal cortex is responsible for higher functions such as problem solving
2. is vulnerable to the negative affects of sleep deprivation
3. you are unable to work efficiently, concentrate, and form memories as well
3 of 15
list the effects of sleep deprivation
1.negative mood
2. unrested muscles
3. impaired judgment
4. fatigue and exhaustion
5. cannot accurately assess situations
6. impaired acquisition and consolidation
of memories

describe the architecture of sleep
1. NREM - inactive brain in a moveable body (has 3 stages)
2. REM - active brain in a paralysed body (1 stage)
6 of 15
explain the functions of sleep
1. NREM is responsible for restoration and
growth, and immunity

1. our bodies have their own clocks
2. endogenous pacemaker use exogenous zeitgebers to help adjust to timeframe
differences
