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.

Best video out there on physiology of sleep.

[@PhysiologyOpen]

Thanks 😊 Glad you liked it

[@ashishbhaskar7100]

Mam your videos are very concept clearing

[@PhysiologyOpen]

Glad they are helping you😊

[@Newton-ized]

loved your teacinng method ❤

[@PhysiologyOpen]

Thanks 😊❤️

[@bian_ka9]

very helpful thank you a lot❤❤

[@PhysiologyOpen]

Most welcome

[@Learner7777]

Mam You teach very well. And give good info in less time
Thanks mam❤

[@PhysiologyOpen]

Thank you 😊

Thankyou very much mam, this VDO is very useful.

[@PhysiologyOpen]

Glad you liked it

[@sejalbamble5905]

Mam thankyou sooo sooo much 🙌🏻♥️🙇🏻‍♀️

[@PhysiologyOpen]

Thanks and welcome 😊

[@vardelliramesh3412]

Very very helpful Mam 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

[@PhysiologyOpen]

So glad

[@satyamsingh-eo2vp]

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

[@heisenbergbroughtschroding474]

Mam thank youuuuu next week is the university.. really helped..

[@PhysiologyOpen]

Glad to hear that. All the best

[@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

[@mohamedazaarudeens1311]

Mam
Pls make a clear note on adenosine once again
Its confusing
Adenosine inhibits VLPO, so maintaining awakeness
Then how does caffeine on inhibiting adenosine keeps us on waking?

[@PhysiologyOpen]

Adenosine doesn't cause wakefulness...it promotes sleep..it's levels increase over the day (it's a metabolite)

[@Ham-os2wk]

🙏🙏🙏Excellent

[@PhysiologyOpen]

Thank you! Cheers!

[@minhajalam5384]

Thanku 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

[@AbhijitMaiti-n2e]

Do you have a Power point presentation format?

[@PhysiologyOpen]

Nope

[@Matt_pitter]

Mam how does REM sleep to nonREM sleep take place?

[@PhysiologyOpen]

Not known

[@Samhita-bg6ku]

maam I did not understand and I feel like I'm not smart enough to understand 😭

[@PhysiologyOpen]

This is a tough one actually...one of the most difficult topics in physiology..watch again, take notes..for mbbs , this may be a little too much as well..

[@lakshmineuroscience]

Imagine the number of mcqs from this sleep physiology

[@PhysiologyOpen]

yeah...many

[@deepakdeepu7433]

Waste of time bro...😢

May you be able to learn better using some other resource. Best wishes
