a presentation for the course “Introduction to Sleep and Dreams.”

Student Presentation 4 - Memory and other functions of sleep (and what happens without sleep) (questions to Katharina)

Please include:

 Memory function of sleep
 (Metabolite) clearance
 Consequences of sleep deprivation
 Other functions (learning, emotional processing)

May include: whatever else you find interesting, e.g. Targeted memory reactivation (current study project)

Memory Function of Sleep

Metabolite Clearance

during the day toxic substances are released:
β-amyloid (Aβ) (antimicrobic, ),

during sleep, anaesthesia:
60% increase in the interstitial space

α-synuclein (transports synaptic vesicles (therefore neurotransmitters in those vesicles))
and tau (stabilisation of microtubules)

Why? Aβ is a byproduct

What do they do? degenerating, leading to cell death

How are they washed away? ISF and CSF

How does this occur during the night? ISF is widened by 60%, less pressure and therefore more exchange
