Amygdala help

  1. Oct 11, 2012 #1
    Am I right that the level of aggression in a person will make the Amygdala Biger?

    What I meen is if you are always aggressive your Amygdala will be very big in Size and stay Big in size?

    So if the Left Amygdala isis Bigger then the Right the person will be more aggressive all the time?
    And is everybody Born with a Bigger Left Amygdala?

    And I know it is Almond Shape but is it the same size as an Almond?

    It appears I may have it backwards, though this is opposite of what I remember, so I'll look a little more.

    " Volunteers with higher aggression scores displayed a 16-18% reduction of amygdala volumes."

    I don't know how amygdalas are in a neurotypical brain, I'll see if I can find anything. Harder to search for that than disease basis.

    Also, a note on the complexity of the amygdala:

    So someone with a High Aggressive will have both left and right Amygdala smaller or just the left?

    They say the Hypothalamas is as big as an Almond.

    How Big is the Amygdala?

    I wasn't able to find out whether they measured left/right amygdala. No access to the paper, sorry.

    This paper describes measurements of amygdala ranging form 1 to 4 cubed centimeters in volume:

    Well I am in the USA so if you had to give a round about gess is the Amygdala the size of a Pea?

    wouldnt it be smaller, it processes primal emotions not causes aggression. A small one would mean one thats atrophied? I mean this would correlate with people who had brain injuries in their amydgala that are more prone to emotional issues.

    Well when I look up Amygdala it says it controls Flight or Fight.

    And people that always worring about things and think people are out to get them I thought it would be Biger?

    in the studies involving brain trauma and later criminal activity, the hippocampus actually plays a bigger role relative to the amygdala, try to look that up
