REM sleep deprivation and conditioned fear in rats
As a test of the hypothesis that REM sleep deprivation reduces fear, the freezing behavior of 60 rats was measured under the conditions of the Bolles-Collier (1976) paradigm. These animals were first exposed to one of three treatments for 4 day s: a dry-environment control, a wetenvironment control, or a 4-day REM deprivation period. Next, the animals were fear conditioned in a square-box and t...
متن کاملSocial partnering alters sleep in fear-conditioned Wistar rats
Social support, when provided following a traumatic experience, is associated with a lower incidence of stress-related psychiatric disorders. Our hypothesis was that providing a social interaction period with a naive conspecific would improve sleep architecture in response to cued fear conditioning in Wistar rats. Rats were randomly assigned to either the socially isolated or socially partnered...
متن کاملFear acquisition requires awareness in trace but not delay conditioning.
The present study explored fear acquisition in differential delay versus trace conditioning in regard to the potential role of the acquired contingency awareness. One of two neutral pictures (CS+) either coterminated with (delay group; n=32) or was followed by the aversive unconditioned stimulus (UCS) after CS offset (trace group; n=32), while startle blink and skin conductance responses (SCR) ...
متن کاملCinnamaldehyde Antagonizes REM Sleep Reduction Induced by Immobilization Stress in Rats
Background and purpose: Sleep and stress are linked in a bidirectional manner. Immobilization stress is a simple model that could be used easily in animal studies for understanding the neurobiology of stress-sleep relationship. Cinnamaldehyde as a herbal medicine with antioxidant activities could be investigated in modulating sleep-stress interaction. Materials and methods: In the present stud...
متن کاملSpatial Learning Paradigm Can Increase Post-Stress Total Time of REM Sleep in Immobilized Rats
Background & Objective: Stress contributes to sleep-wake behavior in all animals. It seems that factors such as learning and memory processes can improve sleep disorders. Therefore, the present study was conducted to determine the effects of stress and learning (spatial memory) on total post-stress rapid-eye-movement (REM), non-rapid-eye-movement (NREM) and waking time in rats. Materials & Met...
