What is Serotonin? - One Minute Medical School

Serotonin is one of the critical neurotransmitters involved in mood and anxiety regulation, and it is a target of many psychiatric drugs. So, what is it, where does it come from, and what does it do?

I didn't really understand this. But then again, I have no medical background. I think a "serotonin for dummies" is what I need.

Serotonin: molecule. Regulates intestinal movement, mood, memory & sleep! & falling in love 😍..

I have no background in medicine, but years of experience in watching university courses on double speed, so I actually understood a good chunk lol.

THANK YOU. I've been trying to find out what it does, but First Aid doesn't explain Neurotransmitter functions for some reason. This quick explanation has finally revealed to me why Serotonin Syndrome involves GI upset and Diarrhea which always confused me.

Wow! Studying for my neurobio pharm test and this was so freaking Running to your page to watch more videos 😄 THANK YOU!!!! Why can't my instructors do this instead of rambling about irrelevant topics for hours 😴😭

"Dude Whats Up" explains it so much better and makes it more interesting.

Sincere thanks for your videos. With regards to tryptophan, it is my understanding that it is not found in greater quantities in turkey meat relative to other forms of meat. The phenomenon of postprandial somnolence is somewhat more complex, with many hypotheses having been posited. The one pertaining to tryptophan is actually related to insulin release following carbohydrate ingestion, which facilitates the uptake of leucine, isoleucine and valine into skeletal muscle, leaving a disproportionately high ratio of tryptophan:other BCAAs in the bloodstream. The LAT1 transporter at the blood-brain barrier, normally transporting all BCAAs, therefore has comparatively more tryptophan substrate, increasing its uptake into CSF, escalating raphe nuclei serotonin synthesis and subsequent pineal conversion to melotonin (a hormone key to the circadian rhythm, darkness anticipation and, ergo, somnolence). Keep up the good work, as your current viewing figures will continue to expand.

So 5 - hydroxytryptamine is in the same family as 5 Meo dimethyltryptamine

I’m not particularly thick, but can’t say I understood any of this 😱😱😱😱😱😱

[RaqibZaman]

Very nice video! I think I'll use it in my article :D

[cristop]

It's converted to 5-hydroxytryptophan to serotonin (metabolized by MAO) and also metabolized to 5-HIAA)

So its' metabolized to both?

What does serotonin have to do with migraines? Does it wax and wane, causing migraines when it is low? Is low serotonin during a migraine the reason people get GI problems (nausea, vomiting, slow peristalsis)? Thanks.

Seratonin increases vascular tone? That totally explains why some SSRI's help people with Postural Orthostatic Tachycardia Syndrome!

[MightyYoungSir]

does any find this topic as important??

[Mijn]

Turkey contains other amino acids that compete with tryptophan.

Times up! You're passed a minute.

[FourtyShorty]

why would 5HT be decreased in the phase of falling in love?

[grrumakemeangry]

I am sorry but I can only concentrate for one minute

[albyv.]
