Effects of overtraining on extinction in newts (Cynops pyrrhogaster).

The overtraining extinction effect (OEE), a phenomenon in which extended training facilitates extinction, has been found in mammals and reptiles. However, fish have never shown OEE. No study has yet investigated OEE in newts, a representative amphibian species. We tested whether newts, Cynops pyrrhogaster, show OEE in a straight-array task. All animals received five trials per day and were give...

Massed-trial Overtraining Effects on Extinction and Reversal Performance in Turtles (Geoclemys reevesii)

Two experiments with turtles (Geoclemys reevesii) examined the overtrain ing extinction effect (OEE) and the overtraining reversal effect (ORE), under massed train ing conditions. In Experiment 1, three g roups of turtles received 7, 14, or 21 sessions of training in a runway situation for food reinforcement, followed by 15 se ssions of extinction. Extinction was faster, the greater the number ...

Effects of Systemic Administration of Oxytocin on Contextual Fear Extinction in a Rat Model of Post-Traumatic Stress Disorder

Introduction: One of the hallmark symptoms of posttraumatic stress disorder (PTSD) is the impaired extinction of traumatic memory. Single prolonged stress (SPS) has been suggested as an animal model of PTSD, since SPS rats exhibited the impaired fear extinction. Oxytocin (OXT) has been recently suggested as a potential pharmacotherapy for treatment of PTSD. In this study, using SPS rats we inve...

Chronic stress and sex differences on the recall of fear conditioning and extinction.

Chronic stress effects and sex differences were examined on conditioned fear extinction. Male and female Sprague-Dawley rats were chronically stressed by restraint (6 h/d/21 d), conditioned to tone and footshock, followed by extinction after 1 h and 24 h delays. Chronic stress impaired the recall of fear extinction in males, as evidenced by high freezing to tone after the 24 h delay despite exp...

Evaluation of immune response after moderate and overtraining exercise in wistar rat

  Objective(s): The effect of prolonged overtraining on cytokine kinetics was compared with moderate exercise in the present study.   Materials and Methods: Male Wistar rats were randomly divided into control sedentary (C), moderate trained (MT), (V=20 m/min, 30 min/day for 6 days a week, 8 weeks), overtrained (OT) (V=25 m/min, 60min/day for 6 days a week, 11 weeks) and recovered overtrai...
