1) feotal sleep
range of weeks for early foetal sleep?
for majority?
20-28 weeks
30-38 weeks
1) feotal sleep
name 3 types of sleep feotals have
quiet sleep
active sleep
indeterminant sleep
1) feotal sleep
what is quiet sleep a precursor of?
eye movements, HR, msucles, ampitude?
what type of brain waves? mixed?
inc/dec as brain matures?
NREM sleep
no eye movements, HR, muscles jerks
LOW amplitude
delta waves early-38 weeks
38 weeks + MIXED amplitude
inc as brain matures (NREM1,2,3 long to develop!)
1) feotal sleep
active sleep is a precursor of?
eye movements, HR, msucles, ampitude mixed?
inc/dec as brain matures?
REM sleep
inc muscle, breathing, eye movements, mixed EEG
dec as brain matures (only quiet inc!!)
1) foetal sleep
intederminant sleep is?
inc/dec as brain matures?
not classified as quiet or active, undeterminned
dec as brain matures
1) feotal sleep
what is feotal sleep time dependent on?
mother’s entrainment
1) feotal sleep
when does the foetal sleep oscillate/sync?
hint: which trimester - early or ending
final third trimester
2) newborn infant
how many hrs a day do newborns sleep?
16 hrs
2) newborn infant
what are 3 main changes in infants/newborns that feotals don’t have?
change in entrainment
c rhythms
daytime naps
2) newborn infant
bio rhythms of infants
infant: ? hrs per cycle
6/8-16 weeks ?
16 weeks+?
3-4 hours/cycle (short)
free running first (no rhythm)
entrainment (rhythm)
2) newborn infant
c rhythms of infants include what type of env factors?
mother’s feeding, melatonin, coritisol
2) newborn infant
diurnal sleep is young or old infants learning to do?
young
2) newborn infant
nocturnal sleep is young or old infants learning to do?
older
2) newborn infant
How many % do infants distribute sleep nights and day?
60-70%
2) newborn infant
naps of infant 3-6 months, 7-9 months, 10-12 months inc or dec from 1-2-3, or 3-2-1?
dec 3-2-1
2) newborn infant
How many months are infants longest night sleep?
2-3 months
2) newborn infant
what are some challenges for infants sleep?
env, routine, arrangements (crib, light, parents, siblings), culture, rocking
2) newborn infant
What are 3 main architecture components infants develop in 4, 6 months?
NREM, REM = 4 months
spindles = 6 months
k-complex = 6 months
2) newborn infant
When do infants (how many months) develop NREM/REM sleep (quiet sleep dec)?
how long is a cycle?
4 months
short 30-35 min cycles
2) newborn infant
spindles develop at what age (how many months)?
pre spindles *4 weeks, shape spindles 6 weeks –> fully developed spindles 6 months
2) newborn infant
k-complexes develop at what age (how many months)?
6 months
3) toddler/child
what 2 components DEC in this stage?
daytime naps
sleep duration (time)
3) toddler/child
what do toddlers develop?
diurnal preferences
4) adolescence
what component (continues to) dec in this stage?
reasons?
sleep duration
phase delay (bedtime sleep later wake up same time, pressure, env school time, screens)
5) old age
what 3 components DEC in this stage?
what 1 component INC in this stage?
DEC = duration time %, efficiency, SWS 3+4
INC =arousals/ awakenings
5) old age
There are gender differences in sleep duration %. True or false?
false
minor diff not sig
males dec SWS more only
5) old age
which sleep stage do elderly still spend most time in?
which dec?
NREM 2 ~60%
NREM 1, SWS, REM
5) old age
inc awakenings/arousals are measured by what?
which NT dec?
respiritory breathing rate
GABA
5) old age
dec SWS is observed by what waves inc/dec?
SWS invovles in what roles?
delta waves DEC amplitude
memory, cogniton, neural regulations, temporal spatial , use dependent,
5) old age
what part of the brain is observed dec in elderly?
pressure
SCN signals

While in utero, what is the most common type of sleep to be observed?
a.Quiet Sleep
b.NREM sleep
c. Active Sleep

d.Minimum core body temperature is negatively associated with sleep onset latency
a.Minimum core body temperature is negatively associated with time from bedtime to first disturbing parents
