Mechanism of sleep physiology | CNS physiology mbbs 1st year lecture

Physiology lecture on central nervous system physiology is about sleep physiology mechanism and wakefulness mechanisms. How Wake on neurons, NREM-On neurons and REM on neurons in RAS and hypothalamus interact with each other to cause switch between wake state, NREM sleep and REM sleep.

Welcome😊

Ma'am in the video you had told that serotonergic neurons that lie in Dorsal raphe nucleus promote wakefulness (wake-on neurons)...but in the text of guyton it is written that.. serotonin help in sleep.... These two things are contradicting each other.... Can you plz clear this confusion ma'am?

[@PhysiologyOpen]

Yes previously it was thought that it has sleep promoting rols but now it is found that its concentration is high during wakefullness. In case of controversy, go to book is Ganong that too most recent one

[@Prelovedbylanina]

mam, I wanna ask about the adenosine one, is it inhibit the vlpo nrem-on neuron or is it activate them? because the effect of adenosine is sleep-inducing, I'm a bit confused how does in inhibit NREM-on neuron but the effect is sleep-inducing?? thank you, by the way, it's a very very helpful video, keep going, mam!

[@PhysiologyOpen]

I think I have mentioned it inhibits the neuron which inhibits nrem neutrons...so it disinhibits nrem neuron...or else I will check the video and get back

[@Prelovedbylanina]

@@PhysiologyOpen oooo I see, thank you for the explanation maam

[@PhysiologyOpen]

Welcome

[@chaimaasalhi9646]

what is basal forebrain ? Is it same as meynert nucleus ?

[@PhysiologyOpen]

Meynert nucleus is located in basal forebrain

[@chaimaasalhi9646]

@@PhysiologyOpen Thank you so much ma'am

Do you have a Power point presentation format?

[@PhysiologyOpen]

Nope

[@lakshmineuroscience]

Imagine the number of mcqs from this sleep physiology

[@PhysiologyOpen]

yeah...many

[@Matt_pitter]

Mam how does REM sleep to nonREM sleep take place?
