Your Brain on Stress and Anxiety



hi I'm dr. John Kemeny welcome to the short tutorial in your brain on anxiety and stress it is essential to know how our brain responds to stimuli which trigger an anxiety response so that you are equipped to deal appropriately with anxiety let me highlight the key areas of your brain that are involved and then I will explain what happens inside the brain the thalamus is the central hub for sights and sound the thalamus breaks down incoming visual cues by size shape and color and auditory cues by volume and dissonance and then signals the cortex the cortex then gives wall sights and sounds meaning enabling you to be conscious of what you are seeing and hearing and I mention here that the prefrontal cortex isn't very key to turning off the anxiety response once the threat is Part B amygdala is the emotional core of the brain whose primary role is to trigger the fearlessness information plus all three theme is associated with an emotional significance the bed nucleus of the stria terminals is particularly interesting when we discuss anxiety while the amygdala sets off an immediate burst of fear the bear st perpetuates the fear response causing longer-term army's typical of anxiety the locus coeruleus receives signals from the amygdala and initiates the classic anxiety response rapid heart beat increased blood pressure sweating and pupil damage the hippocampus is your memory center storing raw information from the senses along with emotional baggage attached data by the amygdala now we know these key parts what happens when we are anxious stressed or fear anxiety stress and of course fear are triggered primarily through your senses sight and sound are first processed by the fans filtering incoming cues and sent directly to the amygdala or to smell and should go directly to the amygdala bypassing the thalamus altogether this is why they smells often evoke very powerful memories any cues from your incoming senses that are associated with a threat in the amygdala whether that threat is real or not current or not are immediately processed to trigger the fear response this is the express way it happens before you consciously feel the hypothalamus and pituitary gland cause the adrenal glands to compound high levels of the stress hormone cortisol dissolved short circuits the cells of theater campus make it difficult to organize the memory of the trauma or a stressful experience memories lose context and become fragment the body's sympathetic nervous system shifts into overdrive causing the heart to beat first blood pressure to rise and lungs to fight the mentally respiration increases and the skiis nerve endings tingle causing goosebump your senses become hyper alert freezing you momentarily as you drink in every beat adrenaline floods to the muscles preparing you to fight the brain shifts focus from digestion to focus on the potential dangers sometimes causing evacuation of the digestive tract through urination defecation or vomit heck if you're about to be eaten as someone else's dinner why bother digesting only after the fear response has been activated does the conscious mind get some sensory information takes a little thoughtful route from the thalamus to the cortex the cortex decides whether the sensory information warrants our fear response if the fear is a genuine threat in space and time the cortex septums the amygdala to continue being on our fear is a good useful response is essential to survive however anxiety is a fear of something that cannot be eat it in space-time most dr. it is that indefinable something triggered initially by something real that you sense but that in itself was not threatening but it is associated with a fearful and the bad nucleus of the striatum perpetuate that fear spots anxiety is a real fear response for the individual feeling anxious and anxiety can be debilitating for the cetera now that you know her anxiety horrible deal in your brain you can pay attention to how we can deliberately use prefrontal cortex to turn off and inappropriate anxiety response wants our attitudes

  1. I can’t stand anxiety! I’ve struggled with drug addiction due to anxiety. I’m still struggling today and it just makes me so upset that I can’t think normally

  2. To bad you use music in the background. It is to loud and very annoying when you are listening to a mood creation, while learning something new 
    in 4 minutes. Which is quick info plus music. It is a marketing thing this music idea and it is very annoying for the brain. To many senses in for minutes..one could say. Thank god you do not switch scenery every second. Our brain is not made for that …

  3. This is the first video I've found that really breaks down what's going on in the brain during anxiety. I wanted to have an understanding of this so that I could better decide what treatments and therapies I would prefer. This was so helpful, I love that you even explained the difference between fear and anxiety as I never understood them in that light before.

  4. For people with post-traumatic stress disorder depression of any kind it is unbearable when medication does not work and your family and friends abandon you the state systems abandon you your doctors tell you it is worse than having a cancer terribly sad to say no one wants to suffer from any type of disease then a few States if you have a terminally ill disease such as cancer you have the right to make a choice to live or die yes there is perhaps a cure for cancers maybe sometimes you cannot beat the odds so you're suffering and pain sadly to say I know this sounds awful but eventually you get to move on from this world to the next and your pain is gone it is hard for the loved ones left behind but if you suffer from post-traumatic stress disorder or any type of depression you are not able to commit suicide or have the choice to end your life in a dignified way your left here to suffer alone everyone has abandon you we have no choice medications does not give you quality of life and the side effects that you get from the medications are you slow and terrible death living with this disease is a terrible and slow death you may live to your 80s and you have to suffer in pain and alone I believe and it's my opinion you do not have to agree with me for those who want to make a choice just like in some states you have the right to choose life or death when you have a terminally ill disease I believe this is a terminally ill disease it is a slow death yes sadly for the ones that are left behind that isn't that the case with all illnesses terminally ill and being abandoned by friends and family you have nowhere to turn not even to the mental health or the doctors the state also has failed me what are we to do live out on the streets alone depressed made to be fun of people judging us only if everyone could trade shoes and walk in another someone else's shoe for just a day or perhaps a week then we are called burdens on society and people don't get things right they say many things about depressed people and post manic stress disorders that aren't even true always making people feel less than and unworthy unloved and unwanted so why not if it is our own choice side to live or die I think that should be everyone's choice not just for the terminally ill I hope these laws will change otherwise people have to commit suicide and horrible terrible

  5. I suffer anxiety / stress and when I sleep at night my heart feels like it's going to explode when I'm trying to sleep

  6. What if there's no apparent trauma or trigger? My anxiety just seemingly comes out of nowhere. I feel all of the symptoms he explains…I just don't know why. That's what frustrates me the most.

  7. The music with the fast beat in the background and the fancy editing are really stressful, mate. Sensory overload in a video about anxiety, quite ironic actually.

  8. I got severe panic attacks mostly from old trama n I can't control it happens out of the blue n I take xanax for it n I wish there's a way to deal with it *breathing doesn't do me anything I need to take a pill or it will last half n hour or more n it's like heart attack or * u gonna die something wrong * i wish this goes away

  9. My therapist gave me a playlist of videos to watch before we start Expsoure Therapy for Trauma. Thanks for using "real english"! I just wanted you to know that therapists are using your work with clients, so please, keep up this important information and congratulations!

  10. The brain is just too complicated and too much for me to handle lol like for real I have anxiety, depression, OCD, irrational thoughts, & gender/sex mismatch…

  11. But what we see are color dots. We form separations and shapes, so we can perceive a wolf attack or fire from some glazy nuances. So we make our perceptions in every aspect. We are second to our amygdala to know or decide what we feel, but we are always first to proper learn about the world in order that amygdala will find an accurate reaction and not expose our uneven perceptions that we might understand correctly when conscious.

  12. Very helpful video. Thank you doc.
    it seems that the anxiety route is more invading to the emotion brain first than the executive's brain area ?

  13. I have flight path brain. Is there such thing? living under the flight path is causing trauma to my brain every time one approaches and flys over I make mistakes or lose concentration this causes my anxiety, fear, pain and depression, brain hurts most often most times a plane flys over.

  15. This video was fascinating. I'm fascinated by the science of anxiety disorders as I was only recently diagnosed with GAD as well as moderate Social Anxiety. (Also, whomever did the writing in this video has VERY pretty writing.)

  16. Thank you very much for this video. I have a question: have the frontal lobes the appropriate connections to regulate the physiological responces of fear such as heart rate increment? Or they do that via amygdala? And how they instract the amygdala to set off those responces?

  17. There are several factors in treating panic attacks naturally. One resource I found that successfully combines these is the Trevs Panic Fixer (check it out on google) it's the most useful guide that I've seen. look at all the great information .
