Term
| NREM Sleep stage 1 is characterized by |
|
Definition
transitional phase-low threshold for waking
3-7 Hz on EEG
occurs max of 7 mins.
Big sign of sleep deprivation: Stage 1 INCREASE
2-5% |
|
|
Term
| NREM Sleep stage 2 is characterized by |
|
Definition
45-55% sleep
EEG shows SPINDLES (12-14hz)
K complexes (slow neg deflect, then positive |
|
|
Term
| NREM Sleep stage 3 is characterized by |
|
Definition
Slow Wave Sleep
3-8% sleep
EEG slow DELTA waves |
|
|
Term
| NREM Sleep stage 4 is characterized by |
|
Definition
Resp. rate decreases
brain temp decreases
cerebral blood flow decrease
blood vessels DILATE
10-15% |
|
|
Term
| REM sleep has two stages... |
|
Definition
Phasic- Irregular breathing, variable HR
Tonic- near paralysis, vasoconstriction, increase blood flow EXCEPT Frontal lobe |
|
|
Term
| REM increase or decrease in duration throughout night |
|
Definition
Increase
20-25% 4-6 discrete episodes |
|
|
Term
| Common features of both REM's |
|
Definition
muscle atonia
rapid eye movement
no thermoregulation
Where erections happen! pychogenic or organic |
|
|
Term
|
Definition
they control BRACs
need "zeitgeibers" to maintain rhythm (alarm clocks, etc) |
|
|
Term
| Basic Rest Activity Cycle |
|
Definition
repeats continuously day and night
occurs in 90 min. cycles (Highs and Lo's) |
|
|
Term
| Strongest and most consistent factor affecting pattern of sleep |
|
Definition
|
|
Term
|
Definition
spend half of time in REM sleep
50-60 min cycles
EEG activation- 2 to 6 months (NREM patterns) |
|

Term
| This can disappear in the second NREM/REM cycle |

|
Term
| Slow wave does what with age? |
|
Definition
|
|
Term
| When you recover, which pattern is first |
|
Definition
| slow wave sleep (NREM) followed by REM |
|
|
Term
| These areas facilitate sleep |
|
Definition
basal forebrain
solitary tract
dorsal raphe nucleus |
|
|
Term
| This provides the clock for circadian |
|
Definition
|
|
Term
| What are the core nuclei of the RAS |
|
Definition
LC- noradrenergic
PPN/Basal-cholinergic
Raphe- serotonin |
|
|
Term
| What is relationship b/t LC, PPN, and RN? |
|
Definition
PPN excites LC
LC inhibits PPN
Both are inhibited by RN |
|
|
Term
| Relationship b/t Schizo/RAS |
