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.

What else can I help you with?
How are brain structures such as the amygdala hypothalamus and prefrontal cortex involved in the manifestation of ptsd symptoms?
The amygdala plays a crucial role in processing fear and emotional memories, often becoming hyperactive in individuals with PTSD, leading to heightened anxiety and fear responses. The hypothalamus is involved in the stress response, regulating the release of stress hormones like cortisol, which can be dysregulated in PTSD, exacerbating symptoms. The prefrontal cortex, responsible for executive functions and emotional regulation, often shows reduced activity in PTSD, impairing the ability to manage fear and anxiety effectively. Together, these brain structures contribute to the persistence of PTSD symptoms, such as hyperarousal, intrusive memories, and emotional dysregulation.
