SLEEP ARTICLES Flashcards
1
Q
What is the role of the Thalamic Reticular nucleus in sleep?
A
It initiates rapid arousal during NREM sleep. Sleep- wake transition.
2
Q
What is the connection between the Lateral Hypothalamus and the Thalamic Reticular Nucleus?
A
Through feed-forward inhibition between the Lateral hypothalamus and the Thalamic Reticular Nucleus, the thalamocortical cells are dis-inhibited. –> inducing a rapig arousal.
3
Q
What brain region initiates and prolongates REM-sleep from Non-REM-sleep ?
A
Ventral medulla (Gabaergic pathway)
4
Q
What is sleepwalking?
A
The dissociation between body sleep and mind sleep.
5
Q
Which brain areas are involved in sleepwaling?
A
Wheras the thalamo-cingulate pathway is activated, other thalamocortical arousal systems are deactivated.
