- Fear is a powerful, yet primitive, emotion that is also the root of much violence, war and suffering. Understanding the neuroscience of fear and how we overcome it has the power to change the world.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations) - วิทยาศาสตร์และเทคโนโลยี
Intriguing. This research holds promise for the thousands of vets suffering from PTSD.
This is incredible. Thank you for doing this work.
Amazing presentation, pure science
this seems more like a solid explanation of fear-based disorders and not as much pertaining to emotions in general
Thank you, I was thinking the same thing!
the way this dude sped through his words, it seems like his amygdala responds to public speaking
Got to know very useful things about fear ... thank you so much.
Very clear & good explanations. thanks.
Great video!
Love you doctor ressler
I can run in fear, I can cower in fear, I can kill in fear, I can freeze in fear, I can fight in fear, I can show fear outwardly, I can control my expressions of fear, I can be aggressive in fear, I can be passive in fear; it's the situation, we construct different expressions of the category of actions we call fear tailored to the moment. That's because there's no fingerprint for fear, it's a constellation of interactions.
PTSD can be understood through constructionist theory as an error of predictions; our brains run lots and lots of prediction loops at all times below the surface and when these predictions are dictated by toxic past events a lens of expected hostility colors all perceptions. Our brains are running these predictions loops and pattern seeking criteria in the background and we've found when we're looking for something we find it; pattern seeking is not pattern identifying. The brain is not identifying what's going on right now, it's identifying what from previous experience this most resembles and until we're aware of it this taints our 'objective' perceptions. We see faces in toast, pattern seeking is not pattern identifying and it leads to massive errors.
I'd like to suggest that instead of saying, "it leads to massive errors.", you say, "It leads to massive clues that still need to be verified with an honest/serious reality check. Too many people dismiss this as errors, and fail to do reality checks. No wonder the world is screwed up. Your opinion is being challenged. Do you fear my opinion? Whether you react in fear or not, depends more on your ability to identify what really is happening right now. Can you do it? If you DON'T react in fear, that can be just as much of an error as an unjustified fear. Reality Check.
Just read Feldman Barrett's book on emotions and trying to understand it more, so good to see a comment from a constructionist point of view under this video.
Hey Dr. Ressler, that was awesome. Brought back a lot of memories, lets me know I learned something :-D
Take control of your amygdala .... conscious control and visualize it and sooth it.... we are not animals or machines but humans..... use positive emotions and feelings to protect our brains this way.
"...use positive emotions and feelings to protect our brains this way."? I think it's more to remind ourselves that there's something still worth living for. Protect our brains? How about protect our lives? That was a good try, tho.
Dennis R. Levesque that's precisely what our amygdala is trying to do... protect our lives.
It would be nice if the studies were linked to (or cited at least) in the description
Exposure therapy REtraumatizes. If the shock/trauma is COMPLEX (is both physically and emotionally damaging), exposure therapy is drastically hurtful. Of course, gentle therapy that carefully cycles through in a natural timing, for example, SE somatic Experiencing or SRT (Self Regulation Therapy), the individual can become more resilient to verbal *exposure*. NEVER do exposure therapy to people who experienced infantile traumas.
I wrote the First Dictionary of Emotions in 1980, based upon the apparent lack of understanding and discourse on the subject.
You/your mind can't process information on the emotions unless or until you have a full vocabulary of emotions. (See the Stroop Effect) of how the mind processes information dysfunctionally.
What happens in the amygdala, doesn't stay in the amygdala.
Go into the snake hole to find the occluded engram(s).
Find the engram, find your hang up, issues, dysfunction or psychological problems. Kick that engram to the curb.
As I have been told, when in a court. Setting, your advised not to get therapy like EMD so your are more believable in the court room, so to increase the chance of a conviction, they want you to cry and shake , if you can give a calm recollection of assault, then "you must be lying" immediate treatment would be good for this kind of trauma would be good, just wish court rooms would be educated on the mental treatments and affects on a person, before deciding on weather it's true or not.
arent self esteem and confidence the opposite of being fearful
Can also be used to build fighter androids!
Is fear the basis of all negative emotions? Do agression, dominant tendencies, jealousy, competitiveness, etc all come from fear? Are they all based on a traumatic experience? Or are they written into our genes? We need so much more on this.
This is an excellent Ted Talk, but it is not about emotions, it is only about one specific emotion which is fear. The title is a bit misleading, it should be the "neuroscience of fear." :)
My amygdala is having anxiety over you spelling it "amGYdala" in the first slide. 😀
Ha haaaa
Why is Freeze regularly missed out.
Yep, in addition to the Fight/Flight trigger, Freeze is often omitted (adrenaline and cortisol response), but more so another two F's words associated of the other arousal pole of survival: Food & F**king (dopamine & oxytocin response); hence the Amygdala's 5F primary behavioral responses. Regardless of which arousal pole, whenever one is hijacked by any of those neurotransmitters, it's never a good idea to make important decisions, especially life-changing decisions ... Just look at the divorce rate or sour marriages once the effects of the "falling in love" phase promoted by dopamine & oxytocin response wear off.
The brain does not produce thought, emotions, sensations. It processes the physical world so our consciousness can observe it, which in turn stimulates thought, emotions, sensations; otherwise there is no self, and if there is no self, who is doing the thinking?
Right now I am generating information, via my computer. The computer is not generating information via me.
Self is constructed, but depends on being able to reflect on reflecting. The ghost in the machine is a hangover from a less scientific age. Also I suspect that your computer is generating considerable information about you!
I completely love your feedback and knowledge. Thank you so much for sharing! Makes perfect perfect sense!
I don't need a scientist to tell me that recreational drugs will make me fearless... haha just kidding! great talk
Oh come on, you can't equate fear with emotion itself. i don't care to learn just about fear. what about happiness, sadness, guilt and the dozens of other feelings we have?!
They all employ different systems, and the system underlying fear happens to be the most tractable one to study
This drug sounds like it could fux with a person's fear response, which is essential to our survival instincts.
No bueno.
Hope he ment "fear lives in the amygdala" as a figure of speak and not literal...
Extemporaneous speaking ? foget that !
So basically what Kessler is saying that we need drugs?!!! If this guy talks to Richard Bandler, he'd slapbitched by his stupidity and greed.
I'm getting OCD with his coat....urgh stop!
You can't "get OCD". OCD is a disease, not a description.
What a horrid film, couldn't watch it all. What a NASTY man: creates FEAR in rats who can't escape it - they are caged and subjected to his TORTURE repeatedly. How can this be justified? Maybe he never questions himself because he believes his actions are 'worthy' and that they might benefit humans? How? When we have PLENTY of people traumatised by war, poverty, exclusion, crime etc. ? We ALREADY KNOW what fear does, how it feels and what causes it. NO excuse for this man (and others) to intentionally inflict suffering on any animal (or person). WHO does this man get his funding from to torture rats (who are clever, family-orientated, creative & intelligent living creatures)?
Couldn't watch to the end, comments suggest it's about finding more DRUGS = pharmaceutical ones not 'recreational' - which are banned mostly - oddly alcohol isn't, who drew the line, when & why to control/'protect' us and how has it moved over time? Once upon a time cocaine was legal for all to buy, now it's for docs to use on us (/derivatives/similar - often unknowingly). Herbs/natural chemicals/weed-hash-dope+ have been used for millennia = now laws say who can use these 9and the untold number of newer chemical creations), not equal, often They use on us/OUR food+ but we aren't allowed by choice.
SICK of being poisoned by propaganda, air pollution, food full of who knows what, yuk water, noxious fumes, extreme fears imposed by others, noise, light-dark wrong times, made ill by complexity... but if I do any of that (including not providing info requested WITH 'proofs', I'd be fined or in prison and am threatened with such by numbers/names of laws I can't understand.
Go eat your salad vegan. This is science.
ew
This is the most textbook anti-science leftist response I've ever witnessed. You've made my day, my week and given me material for a million memes. Thank you.
What you're onto here, is that a lot of "scientists" can never see that other living life-forms are more than just objects to be studied for their own benefit. That's what makes bigots bad scientists. They always come up with bad theories and bad explanations to justify/maintain their bigotry.
