The present study explored the behavioral stressing action of a 15-min forced swim test (FST) session, changes in CA3-medial prefrontal cortex (mPFC) connection responsivity, and whether ketamine reverses such changes. Two groups of male Wistar rats were subjected to a 15-min FST session. Sixty minutes later, they were injected with either saline (stress [STR] SAL group) or ketamine (STR KET...
Ketamine is a dissociative anesthetic that has been proposed to be a useful alternative in cases of a poor response to other treatments in patients with depression. Remarkably, beneficial clinical actions of ketamine are detected once its psychotropic actions disappear. Therefore, clinical actions may occur independently of dose. Most current studies focus on actions of ketamine on neurotrophic...
