Final answer:

The hyperactivity of the amygdala is a key factor in explaining hyperarousal in PTSD patients.


Explanation:

Hyperactive amygdala most likely explains hyperarousal in PTSD. The amygdala is crucial in processing emotions, fear learning, and fear expression, and in PTSD patients, it shows increased activity, contributing to heightened stress sensitivity and fear responses. This hyperactivity of the amygdala, along with reduced activity in the hippocampus and prefrontal cortex, plays a significant role in the neurobiological underpinnings of PTSD.
