  1. Well…that explains a lot. The left hemisphere of my brain was damaged after a near-death experience. The damage showed up most heavily on the left side. The loss of oxygen had to go somewhere and that's where it chose to park itself; on the left side of my brain.

  2. Thanks for your great 'emotions videos'. I have prolonged ptsd, anxiety and grief due to sudden death of my parents and other issues. its great to learn again about the brain so I can have an idea.

  3. 1: There are two amygdalas, not one.
    2: They don't just generate negative emotions. They generate ALL emotions, good or bad. They also generate first impressions, interpret facial gestures, etc. They are at the core of our personalities.
    3: Men and women generate fear in opposite hemispheres, so the notion that positive is left and negative is right, is incorrect.
    4: Don't overexplain so much.

  4. I think what he means by negative emotions are EMOTIONS which are harmful due to the spectator's [person]
    interaction.

    Take hormones into consideration in relation to the nature it has with emotions and memory. Representations remind us of memory; our logical thinking is on the left side (experiences) and our creativity (abstract thought) is on the right. Obvious negativity tends to come from experiences no?

  5. Just want to say that not everybody with this damage behaves bad…some of us actually behave To Well in most situation. Take Attention Defecit Disorder for example. I dont curse unless severly hurt or provoked…but time management and memory recall is difficult, and I get hurt psycologically to easy. I also get bored very easy, even though I try very hard to sit still and stick things out anyway, and usually I try not to show it, in order not to hurt anyones feelings by ignoring them, often because I feel sorry for them and think they deserve beeing listen to. I also tend to keep shut a lot so I dont say things by impulse because I analyse situations and informations too slow usually.

  6. I watched this woman on Ted talks who said that the left hemisphere is responsible for rational thinking while the right is much more creative and positive! ! you confusing me

  7. There is quite of bit of contradictory research on which hemisphere is associated with 'negative or positive' emotion. I was just reading how the right amygdala is associated with happy/joy feelings and the left with fear….so is it 'flipped' in the cortical region? Also, it's interesting that it is our left-hemisphere that is more socially 'independent' or 'I' focused…so for studies to associate it with connection and relating with others…doesn't make sense. I have to wonder how much assumption or projection is being made within these so-called scientific studies…

  8. The problem is Phineas Gage's effects were only observed by his friends. Emotionally he probably always had those feelings of disgust inside but used his left prefrontal cortex to keep his emotions controlled. We all live in a facade because we learned to suck up our emotions and put on a happy face, which causes a lot of depression because we aren't being real with our emotions like we naturally were as children.

    Also when test subjects view videos, some people may find pleasure in grotesqe videos which would give a different effect than you may be suspecting. There is a huge problem with observing without understanding what is really be going on inside someone's head. Even if you ask the test subject what they felt they might not know because many people are very suppressed or they could lie if they feel they're wrong for feeling pleasure. You can come up with many false conclusions experimenting this way. Sadly this is the state of modern science.

  9. I find it difficult to relate brain function to social influence.. in a medical aspect i think its irrelevant to the brain itself. EXAMPLE; IF YOU GO TO A WAR TORN COUNTRY, PEOPLE ARE NATURALLY SCARED ,ALTHOUGH BROUGHT ON BECAUSE OF ACTUAL ISSUES OF ATTACKS. JUST BECAUSE A PERSON ISOLATES THEMSELF AWAY FROM ABUSE AND VIOLENCE DOESNT MEAN ITS BECAUSE THEY FUNCTION LESS .. POSITIVELY THEY WOULD BE DOING WHATS WISE AND PLANNED SO THAT WOULD INVOLVE THE LEFT HEMISPHERE ..POSITIVE THOUGHT PROCESS.. IF A PERSON SITS IN THE MIDDLE OF BOMBS FLYING AND ADMIST THE VIOLENCE RATHER THAN ISOLATING THEMSELF FROM THAT THEN THEY ARE HAVING A MISFUNCTION with HIGH RISk TAKING MECHANISM. So i disagree with his introvert extrovert theory. An introverted person still may be a very sociable and high functionsble person. Many extroverts whom are heavily associated to others often engage in negative high risk situations

  10. I liked your video, but I found a few things wrong with it.

    1. I know that research on borderline personality disorder suggests a frontal asymmetry whereby the left hemisphere is more active than the right. However, if the left frontal lobe was more associated with positive emotion than negative emotion, it would not follow that individuals with borderline personality would experience chronic dysphoria and unregulated negative emotion.
    2. I think the error here is that you are making quite a few generalizations. It is incorrect to assume that the feelings of disgust associated with gore are generalizable to other forms of disgust provoked in different settings (e.g., disgust as a reaction to moral repugnance, disgust as a reaction to disgusting tasting foods, etc.)
    3. Even if it were the case that disgust primarily resided in the right hemisphere, one should not generalize this finding to all negative emotion. For example, I recently stumbled upon an article that suggested that anger and frustration are primarily processed in the left hemisphere.
