Alteration of the neurogenesis and long term potential of olfactory bulb in an animal model of PTSD.

Failure of extinction of fear-conditioned traumatic memory is the main pathology behind post-traumatic stress disorder (PTSD). Functional and structural dysfunctions in the olfactory system are implicated by studies in PTSD patients. However, little is known regarding the neurobiological networks of trauma‑related odor sensitivity in PTSD.
