How the Amygdala Works
ฝัง
- เผยแพร่เมื่อ 8 พ.ค. 2024
- The amygdala detects important features of the environment and it can trigger the fight or flight response. This brain region used to be thought of as the brain’s ‘fear center’ or sometimes as the emotional core of the brain, but in recent years neuroscientists have discovered that the amygdala’s function is more general. It now appears that the amygdala’s function is to detect important and relevant features of our sensory experience, and it activates most strongly when those features are unexpected. More specifically, the amygdala can be thought of as a prediction error detector which is sensitive to things that are biologically relevant and/or important for the task at hand.
This video explains how the amygdala works, including a discussion of amygdaloid nuclei anatomy, how the fight or flight response works and how the amygdala triggers it, how the amygdala can be “hijacked” and lead us to doing things we later regret, and how we can calm our amygdalae if we experience the amygdala hijack often.

The whole first 39 seconds before I turned it off would have been a whole lot better without the blaring music. Do you usually sit in educational lectures with music blaring in the background?
Love it, but would prefer without the music
Thank you! And thanks for the suggestion!
Agreed
The music was right on point as he began to talk about how your amygdala reacts to mudical tones
Yeah. Music is distracting.
Agree, had to turn it off
Explains so much of why I get certain sensations when I get panicky. Ty for this explanation...it helped
I love your video but have a request. Would you consider deleting the background music? It makes your voice hard to listen to. Thank you
Thank you. Perfectly presented.
Enjoyed this very much! I’m a psychologist working with neurologically impaired individuals and see the impact of the unmodulated amygdala all the time in individuals with frontal lobe injuries. This makes a lot of sense
Keep up the good work!
Your videos are top notch. Thank you.
So well done! This was so in depth and fantastic. I've been doing a lot of reading of Joseph Ledoux and his work on fear processing lately and I really like how you steered clear of claiming it was a "fear" circuit. Evolutionarily it looks like it's a salience and survival circuit and that our perception of fear is something we cognitively tack on after the fact. Loved the part about Amygdala hijack and the b-roll is 🔥
Thanks so much Taylor! I think you might be right about that. Ledoux is certainly an important figure in this area, so I need more of his work. I've also been reading about the "extended" fear circuit, which involves a more dispersed network and seems like a more realistic picture of fear processing compared to a single brain region doing everything.
Exelente, video muchas gracias por compartir.
This is such a good lesson. Thank you so much for uploading this since I got to control my behaviour better after recognizing when my amygdala is taking action
I’m so glad to hear that you got something out of it. Thanks for checking it out!
You have a very pleasant personality and therein much beauty as expressed through your intelligence. Your the type of instructor who can do the most good. Thanks for sharing and thus enhancing my understanding of the subject matter.
Thank you !
Keep up the content man hidden gem!
Thank you!
Great, thanks !
Music is destracting for me
Interesting talk, thank you for sharing. It's seems like to help people over come PTSD, we need to learn how to build a squelch knob (used in old radios to differentiate between noise level and signal).
Great point and thanks for your comment! I think something like that squelch knob might already be in the human brain: the prefrontal cortex!
Brilliant one. Can you make one on judgment and decision making? . I have watched pfc video.
Thank you! And thanks for the suggestion. I’ll put that on the list for future videos!
Thanks.
I really enjoy watching your videos, and learn so much! Thank you for your work! Would you be willing to make a video about the (triune) lizard brain and why is wrong, and what model we should study instead? I've read the lizard brain is a myth but then what model should we use?
Thanks for your question and suggestion! I’d love to make a video about that in the future. You’re right that the triune brain model is something of a myth. I think the alternative is a more nuanced understanding of the whole brain as a complex system that functions through network interactions. Still, there are aspects of the triune model that are useful and should be retained.
Often Amygdala damage (not over active) cause *No Fear* , but the inverse is possible. Also Visual Snow Syndrome and Hyperacusis (Sound Sensitivity) are strongly related to the Amygdala Functions, since any issue with it could trigger these conditions.
Muito obrigado. Eu achei sua explicação excelente.
Obrigado por todos os seus comentários! (A propósito, estou usando o tradutor do Google, então me desculpe se minha gramática estiver ruim)
Your amazing
I´alsso recommend Havening technique to regulate the amydala.
Wonderful and informative.
I am recovering from years of narcissistic abuse. Mental abuse on a very high level and physical abuse. As bad as it can be..
I can’t seem to recover I guess it takes time.
My psychiatrist handles soldiers with past and he is frustrated.
Any help would be appreciated.
Andrew, this was excellent... I had a stroke (tia), just after the world closed down for covid, March, 2020. The doctor at the hospital did an mri
of my brain ( my whole head, down to my neck).. Would the results possibly have shown any amygdala function, either good or bad results? It's sort of an awkward question, but I'm curious if the amygdala would have shown up. Does this make sense? My thanks, jan
Cut the music. You will do better.
True. It is distracting
Two things: Would you say the prefrontal cortex is that FILTER to which people refer when they say one is lacking a filter? And in music, is it that break in which the music momentarily pauses before continuing that serves as a hook to draw up atavistic emotions stored in the limbic region of the brain -- e.g., the Supremes' "You Can't Hurry Love" -- that break in the music which the listener comes to anticipate (perhaps with relish) after hearing the song more than a couple times, because it elicits an emotion embedded deep inside with which you are subconsciously very much in tune (no un intended)?
The music is so disturbing.
Here after August-d solo album
Could you provide a video of how it is explicitly exploited by scammers and tools to help people avoid it and recover from it?
I don't able to create any memory (2016)
I don't feel feeling. Can you tell reason ?
Hi. You said "mindfulness" and "pay attention to the causes" to calm de amygdala... what about exercise contribution to it? is it neglectable?
Great question! I should have included this in the original video, but there is research suggesting that exercise helps to reduce the amygdala's reactivity in response to fear and that this may be one of the mechanisms responsible for the anxiety-reducing quality of physical exercise: www.nature.com/articles/s41598-019-56226-z
I don't know if I'm soothed or irritated that this video confirms many things I had been thinking on my own. oof
I won’t finish this video bc of the background music… hmmm
Can you help me understand why my son has contamination OCD since last September 1 2022 literally overnight after having the evil vi rus early Aug. What should ppl who suffer from this focus on? I'm going to relisten to this video but just desperate for answers. This issue is heartbreaking what ppl are going through. My son struggles with fear of urine and he feels like something is always poking him, brain fog and memory issues. He had a Nuroquaint MRI. We haya FMaps neurologist and the analysis of the MRI numbers shoes he has a mold infection. His hippocampus asymmetry is off the right side is smaller than the left side. She says he has inflammation and no permanent brain damage but there is damage. Basically inflammation damaged but it can rejuvenate. I'm now wondering of the inflammation is hindering the amyglydala and it's causing memory issues. He's only 21. It's been a tough journey. 😢♥️🙏
Sir, does conscious attention convert Short term memory into Long term memory in human ?
Attention is definitely very important to the process of forming a long term memory. But I wouldn’t say it converts short term into long term memory, because for something to be a short term memory you have to pay attention to it. I talk about this in an interview with Artem Kirsanov (go to 38:15) th-cam.com/video/nFtouEhBj7I/w-d-xo.html
@@senseofmindshow 😊
the subscribe pop up is too redundant please stop overdoing it it distracts me from enjoying the video
Sir, is human long term memory capacity unlimited?
I haven’t studied this specifically, but according to one article in Scientific American from 2010, the human brain may be able to store around as much as 2.5 million gigabytes of data… but that makes a lot of assumptions about how our brain’s memory system works. The true answer is that memory is almost certainly not unlimited, but its capacity is really, really big.
@@senseofmindshow could you please give me an idea about how much big it is?
damn
ugh TAKE THE MUSIC OFF
Well explained, thank you. Beside that I find animal testings are barbaric. Plus: They are mostly not really useful for humans. For all the "Shut-Uppers" rising now: It is standard that under every experiment you will find the note: "However it is not clear if it applies to humans".
