Hi,
The amygdala is the part of the brain that processes fear, threats and anxiety. The amygdala is involved in the assessment of threat-related stimuli and is necessary for the process of fear conditioning.
It has been found via PET/neuroimaging studies that the amygdala is hyperresponsive in PTSD .
Also when people are presented with personalized traumatic stories,combat sounds, combat photographs and trauma-related words the amygdala also shows signs of being hyperresponsive.
The amygdala is involved in the assessment of threat-related stimuli and/or biologically relevant ambiguity and is necessary for the process of fear conditioning.
In PTSD neuroimaging studies suggest that the changes that occur lead to a shift from a brain where:-
- the stress, reward, and self-reflection systems operate in learning mode. This allows people to investigate and enjoy the world around them. This allows them to obtain and remember knowledge that enhances their life
-to a brain operating in survival mode. This means that one becomes defensive and prone to negative emotional, cognitive, and behavioral reactions.
I hope this helps.
