- This video focuses on the serotonin receptors and their molecular biology, pharmacology, and psychological effects when stimulated.
Serotonin (also known as 5-hydroxytryptamine or 5-HT) is a neurotransmitter molecule used in a huge variety of neurobiological processes. There are 14 different 5-HT receptors in the brain and body, each with a fairly unique intracellular signaling mechanism and distinct psychological effects.
What do you think of Sense of Mind’s new style (more visuals, shorter videos)? Let me know in the comments.
This is the first in a miniseries on the neurobiology of the serotonin system. Link to the rest of the serotonin videos: • Serotonin Miniseries

Just have to comment again to say that you are ridiculously good at explaining this stuff, it's so easy to follow and understand - I really hope this channel gets the growth it deserves
Very much appreciate the compliment.
I had been searching how does few Serotonin Antagonist drugs help in increasing Serotonin levels, (but could not find it anywhere on internet) but you answered that specifically in your video. Thanks!
This is great! I like the way you don't assume that people know exactly what you're talking about and provide context and links where required. Keep up the good work!
Thank you! I'm so glad it made sense. Keep it up with your channel too! 💪
Your team’s explanations are so clear it awesome. I can’t see how this channel won’t blow up with views
Thank you so much!
This video is underrated!
Thanks for the deep dive! Really excellent stuff!
Honestly, soooooo good! Just what I was looking for!!
Love the timestamps organization. Subscribed!
Underrated video production value. I’ll browse your page more later. Love neuroscience
Thanks so much for the compliment and for checking it out! 🙌
The video was highly informative and very well put together
I really enjoyed it.
Thanks bro !
Thanks for checking it out!!
so happy I came across your channel! Definitely subscribed. I'm doing research for a research paper & presentation on the effectivity of SSRIs and MAOIs for one of my senior biochemistry theses. This series (and your references) has been so helpful, as I am have very little background in neurochemistry. Super organized, clear, and interesting, thank you and great work!!!
Thank you very much! I'm glad to hear it could be of help.
I'm so happy I found you. I love neuroscience and will definitely watch some more videos.
I'm so glad to hear that! Just curious, are you a student? I'm just interested in learning about where people are coming from. Thanks for being here!
@@senseofmindshow Yes, I am a psychology student. We talked about the serotonin system in a course and I wanted to know more. That's how I found you.
@@Elena-tt6gs Very cool. Good luck in your degree! And never hesitate to reach out if you want to suggest topics for future videos!
Thanks!
Thank you so much!!
Thank you so much! I finally understood!
Great to hear!
Great or glad😜@@senseofmindshow
5HT1A receptor is an autoreceptor so it stops the release of serotonin from the cell if there is high accumulation of serotonin accumulation in the synapsis. Please correct me if I am wrong. You said that 5HT1A receptor removes serotonin from the synapsis back into cell. This is job of SERT. Maybe I am just misunderstanding your way of explaining it but I wanted to clarify?
Thank you for pointing out my mistake. That was an unfortunate fumbling of words on my part. You’re correct that presynaptic 5HT1A autoreceptors do NOT function as reuptake pumps. They instead trigger a mechanism that inhibits further presynaptic release of 5HT.
@@senseofmindshow Thank you for your reply!
Thank you for helping me study for my RANZCP exams x
Clear explanation❤❤❤
Thanks so much for watching!
Excellent
Thank you!
Will Get Back...
With Gratitude,

Excelente trabalho. Obrigado
obrigado por assistir o video!
Great job
Thank you!
You have a new subscriber June 30,2022!! So excited to learn from you..🥰
Much appreciated!
@@senseofmindshow yup!!!
Great video man , working with more diagrams would make it a plus maybe you could use an ipad to walk us through and you could include a few analogies to make us understand
Appreciate man!
Do you also have a serotonin transporter series?
Thanks for watching! And no I’m sorry I don’t right now… I will look into that for the future though.
@@senseofmindshow will wait for that 😁
Great video! Do you recommend any pharmacology books?
Thank you! And sorry I don’t. I wish I did! The articles I referenced are the best I can do on that front :)
Okay! Thanks! :)
Is there a difference between the word expressed and the word found? When we are talking about the presence of serotonin receptors or other NT
Excellent video well explained
Can you give us key reference papers please
Thank you! For a full list of references, see the caption for this video. But, if I had to choose, I would say the most important paper is this one: pubmed.ncbi.nlm.nih.gov/32522572/
Good staff. But can you explain what happens during bipolar disorder syndrome? For example, a relative of mine is given leponex. The symptoms almost disappear. When the dose is reduced (leponex is co-given with haloperidol) the symptoms de-masked slowly. I have noticed that when he starts showing the initial symptoms slowly (not straight away in few days) he is acting like OCD with some signs of compulsions, like going out to have walk. What happens in such situation at that exact point? He has low serotonin or high (he is agitated a little)? Is there a possibility that his brain after usage of leponex and blockage of HT2 receptors starts to build up new HT2 receptors for compensation or making new serotonin. Thank you
sex, digestion, LSD, emotions
4:00 neuromodulator. Relatively weak effects/
about 75 percent of serotonergic neurons also have
glutamate receptors
15 subtypes of serotonine receptors
10:00 anti psychosis, antidepressant, antianxiety, sexual arousal in some women
Please tell me how to find this table.
Is there a video on synaptic pruning by any chance? 🥰
Unfortunately, I haven't gotten to that topic in any detail yet (though I plan to eventually do a video on neurological development)... However, I VERY briefly discuss synaptic pruning in my video on neuroplasticity (th-cam.com/video/q-iQGoxmRkM/w-d-xo.html)
Is possible unblock serotonin receptors
Sir ,I know that human brain has no nociceptor.
But if I ask you this - If someone touches my brain gently,will I be able to feel that?
As far as I know, the brain has no touch receptors at all so I think the answer is no.
@@senseofmindshow ok sir
You is handsome dude!!!!🥰
It's probably just a camera trick ;)
@@senseofmindshow it's no camera trick you really are handsome with a great sense of humor dude!!!!
I've been wanting to learn more about serotonin and this video literally gives everything I was trying to find out! Your videos are produced really well and the content is great, also you look so much like link from Good Mythical Morning!
I've noticed you also post a lot of shorts, I think you'll find this video helpful: th-cam.com/video/bmnVYwVEzpE/w-d-xo.html
That's really great to hear! Thanks for checking it out and sending that video about yt shorts, I also post them on reels on IG, and they seem to do better there but I've definitely noticed less traffic on shorts lately. Also, that I look like Link is really funny. I had never heard of him before but I agree we could be long lost twins.
why stimulation of serotonin receptor a2 lead to depression
I think my serotonin receptors are fried.
you should realy get more light on you....
