2. What is the neurobiological basis for the efficacy of exposure techniques with individuals who have experienced a trauma?
By remaining in a physiologically arousing situation, the parasympathetic nervous system (PNS) returns the body to a restorative
mode and the limbic system resets its ability to regulate the HPA axis.
These techniques reduce levels of neurotransmitters in areas of the brain impacted by trauma.
О
Through repeated stimulation, the hippocampus becomes less reactive to traumatic memories and eventually those memories fade
from the brain altogether.
These techniques accelerate the rate of myelination, leading to more efficient communication in neural pathways associated with
safety and emotional regulation.

Exposure therapy has been related to the neurobiological basis of fading away of memory by continuous simulation thereby resulting in the release of fear. Thus, option C is correct.

Exposure therapy has been the psychological treatment that has been addressed to the person facing the long-termed trauma. The therapy has been helpful in dealing with the post-traumatic disorder.

The therapy has been mediated with the reduction in the sensation to the fear. It has have been achieved in vivo or by flooding.

The therapy has resulted from a decreased response to the stimulus with continuous simulation and thereby results in the fading of memory. Thus, option C is correct.
