Chronobiology Flashcards
1
Q
Wakefulness
A
High freq beta waves
2
Q
Drowsy
A
Alpha waves
3
Q
Stage 1
A
Theta waves
4
Q
stage 2
A
sleep spindles and K complexes
5
Q
Stage 3
A
delta waves
6
Q
Stage 4
A
more delta waves
7
Q
REM
A
fast waves with sawtooth waves
- dreams occur
- EEG appear awake
- sympathetic tone dominates
8
Q
6 transmitters keeping you awake
A
Ach glu ne hist serotonin
9
Q
Ach
A
Released for Basal forebrain and Laterodorsal and pedunculopontine segmental nuclei
10
Q
Basal forebrain
A
Releases Ach- during wakefulness and REM
11
Q
Laterodorsal and pedunculopontine segmental nuclei
A
Release Ach- promotes wakefulness most robustly via projections to thalamus
12
Q
NE
A
Released from Locus Coeruleus
13
Q
Locus Coeruleus
A
releases NE- during wakefulness some during NREM and NON during REM -attention and task performance -overfiring causes insomnia and anxiety - has to have optimal release
14
Q
Histamine
A
Released from tuberomammilary nucleus
15
Q
Tuberomammilary nucleus
A
releases histamine
increased firing while awake>NREM>REM
