Serotonin 5-HT7 Receptor in the Ventral Hippocampus Modulates the Retrieval of Fear Memory and Stress-Induced Defecation

摘要

Background:Patients with posttraumatic stress disorder or panic disorder are often troubled by inappropriate retrieval of fear memory. Moreover, these disorders are often comorbid with irritable bowel syndrome. The main aim of the present study is to elucidate the involvement of hippocampal serotonergic systems in fear memory retrieval and stress-induced defecation.
