The video delves into the complexities of serotonin, explaining its role beyond just being a happiness chemical. It discusses what serotonin does, emphasizing its influence on cognition, emotion, and motor control, and why serotonin is important, particularly in adaptive responses to adverse conditions. The transcript outlines two pathways influenced by serotonin receptor types: 5HT1A and 5HT2A. The former is associated with passive coping, improving stress tolerability, while the latter promotes active coping, facilitating changes in behavior or outlook to overcome stressors. The discussion extends to how different drugs interact with these pathways. SSRIs primarily stimulate 5HT1A, aiding passive coping, while psychedelics like psilocybin act on 5HT2A, promoting active coping. The video touches on the therapeutic potential of both SSRIs and psychedelics in treating depression, albeit with different mechanisms. It also highlights potential drawbacks, such as emotional blunting with SSRI use and the risk of developing unconventional beliefs with excessive 5HT2A stimulation.

Great video! I'm wondering about something you mentioned. You said that SSRIs act on the 5HT1A receptors to increase, but I thought their primary action was on the 5HT transporter? Thanks!

@PsychoFarm 6 ай бұрын

You’re correct- primary action is on the 5HT transporter! The theory from the paper is that because 5HT1A is the most common serotonin receptor in the brain, when SSRIs increase serotonin by blocking the transporter, it’s the 5HT1A receptor that most of that serotonin goes to.

OMG this makes so much sense. SSRI cured my anxiety but stop me from making music. Then one day I tried psilocybin and feel like this thing works like SSRI but i can make better music. I think SSRI is wonderful if you have an office job, while create job you are better off with psilocybin

Really great video ! In my opinion, it rehabilitates SSRIs. Moreover, this video helped me put into words a diffuse feeling about some heavy users of psychedelics (I'm thinking in particular of regular DMT users) who have always seemed to me particularly versed in bizarre stuff, even compared to other psychonauts. I'd love it if this picture could be completed with MAOIs and MDMA science !

@Nikolay76Gogol Ай бұрын

Before jumping to a conclusion that SSRIs have been “rehabilitated”, I would suggest to look at the clinical effects of these substances: drowsiness and lethargy, emotional blunting, loss of libido, occasional agitation ('activation') and dysphoria. I don’t think it’s appropriate and beneficial to create artificial emotional blunting.

Thank you, I’ve never heard of that article before. I like how you helped break it down for us. When it comes to those crazy amount of receptors, you may want to consider checking out Leo & Longevity’s channel. He has a playlist on Serotonin that goes more deeply into the neurotransmitter and receptors than anything anywhere else on the internet. Anyways, thanks again.

Thanks so much for your service to spreading good information! Am very pleased I found your videos at this time in my life (switch careers to psych in 2020 and am in school to become a psych provider eventually). Appreciate the shoutout to the carhart-harris paper and will be diving into that. Looking forward to the antidepressant course as well. I wonder if you have any more repositories of good papers or reference lists that would help one dive deeper into this material and avoid at least some of the wading through super dense, hard to digest papers on pyschopharmacology?

This really puts into perspective the danger of stopping SSRI treatment without tailoring down the dosage (as a patient may be inclined to do when confronted with the emotional dulling). I would imagine that in response to the artificially elevated levels of serotonin induced by the SSRIs, the 5-HT receptors (1A in particular being the most numerous) would down-regulate their expression to counteract the effect (curious if endogenous 5-HT biosynthesis would also down-regulate in response). So when someone stops taking their meds, and those inflated serotonin levels drop, they have even less capacity to passively cope than they would have had before taking the SSRI to begin with, potentially exacerbating a mental health crisis. Great vid! Going to have to go delve into that Carhart-Harris paper now!

Amazing video. Regarding the last part, Balance and Considerations, the Slate Star Codex articles "Why Were Early Psychedelicists So Weird" and "Mental Mountains" offer some fascinating insight into the potential of "becoming a crazy person" side effect of HT2A agonism.

ahha! so that's how you look like! almost exactly as I thought! on serious note: I've been taking SSRIs for severe anxiety and they helped me tremendously BUT I wish I knew all this receptor type stuff before. I wish I had sth to stimulate the other receptors too in a legal and safe way ;p You are extremely helpful with your education! Thank you. Also, I've learned in the meantime that I'm autistic- and as much as I'm better with adopting to some stressors, many are not possible to cope with- becasue of innate way of how my brain processes stimuli. The thing is, autistic people, especially ones unaware that they are autistic, are super sensitive to how current human civilization works, and many psychiatrists/therapists likes to omit influence of the environment, even if it's adverse to the point of breaking a person :/ Just a digression, but sth to think about for psych students ;) (also, I take pregabalin as , at least my psych says it works in synergetic effect with my specific type of SSRI I take, seems to be true)

Hey man, long time watcher first time commenter. Love your stuff. Regarding your new product, I am hoping it will be of help when I sit for my boards in the latter half of the year but even more so for general knowledge and real world practice. Not sure how PRITE compares to boards but would you say the boards goes into these kinds of details? I plan to back the kickstarter regardless, though am currently doing a rotation abroad and had a credit card SNAFU, will back you as soon as its resolved!

@PsychoFarm 6 ай бұрын

Appreciate the message! I'd say the board doesn't go into this level of detail on these things, which is to say you'll never be asked a specific question that a video like this covers... but I'd argue that when you have a good framework for organizing knowledge, you intuitively are able to get a lot more questions correct. On tests, I outperformed smarter people who were better studiers, because I focused more on understanding things and less on facts. The pass rate is quite high, and if you're not an incredibly anxious test taker, and put in a minimum amount of effort, statistically you will pass. I found most of "conventional" board studying to be meaningless collections of facts. I guess what I'm saying is.... you're probs going to pass... you might as well learn some things you enjoy along the way. WTF do I know though, I'm just a Farmer.

This. He should have used the term Indifference. Indifference is often confused with terms like stoicism, equanimity or composure which can be described as being at peace while deeply emotionally involved and active.

@@Benjamin20672those terms contradict each other though. You cannot have peace alongside passion. Passion invariably leads to conflict. What you reference isnt stoicism, it's actively detaching, dismissing, and disengaging from things you cannot control and upset you. That is not peace.
