Hello :)
I have a question about the sleep-wake cycle/circardian rhythm:
During adolescence is melatonin released at a later time (hence the reason adolescents fall asleep at a later time) or is less melatonin produced during adolescence which causes sleepiness at a later time?
Thanks :)
scarletmoon:
Melatonin is released 1-2 hours later

The Sleep-Wake Cycle shift in adolescence is due to biological/physiological changes associated with the hormone Melatonin (responsible for sleep onset) being released later in the night, which causes adolescents to 'feel sleepy' 1-2 hours later than younger children.
This also makes it difficult for adolescents to wake up earlier in the morning as their 'circardian/biological clock' (which is controlled by a region in the brain known as the Supachiasmatic Nucleus and works by detecting how light or dark it is) has been shifted 1-2 hours forward :)

Hi guys! I'm struggling to get my head around association areas and the different association areas in the cerebral cortex lobes and was wondering if anyone would be able to elaborate and explain what association areas and the different ones in the four lobes are? - Sorry if this is a bit vague!! :)

Hi guys
when we are writing up a hypothesis, are we allow to write it like if we are writing an chemistry report? Cos my teacher said we have to use the hypothesis recipe which is a bit confusing to use sometimes do I still lose mark in the final exam if I use the normal hypothesis?
