Early life stress and novelty seeking behavior in adolescent monkeys.
Recent evidence suggests that early exposure to mild stress promotes the development of novelty seeking behavior. Here we test this hypothesis in squirrel monkeys and investigate whether novelty seeking behavior is associated with differences in cerebrospinal fluid (CSF) levels of the serotonin metabolite 5-hydroxyindoleacetic acid (5HIAA), the dopamine metabolite homovanillic acid (HVA), the n...
متن کاملL-carnosine Improves Short-Term Spatial Recognition Memory and Passive Avoidance Learning and Memory in Streptozotocin-Diabetic Rats
Background and Objective: Diabetes mellitus (DM) affects synaptic plasticity in the hippocampus, leading to impairments in learning and memory. L-carnosine, an endogenous dipeptide, is reported to exhibit anti-diabetic and antioxidant effects. Therefore, this study was designed to evaluate its effect on learning and memory in diabetic rats. Materials and Methods: In the present study, male Wis...
متن کاملAcute stress does not affect the impairing effect of chronic stress on memory retrieval
Objective(s): Due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. This issue was tested in this study. Materials and Methods: Adult male Wistar rats were randomly assigned to the following groups: control,...
متن کاملRecognition Memory: What's New in Novelty Signals?
A new study indicates that signals distinguishing between new and old stimuli are present very rapidly in the human brain, but only when subjects are motivated by explicit reward instructions.
متن کاملEnvironmental enrichment and chronic restraint stress in ICR mice: effects on prepulse inhibition of startle and Y-maze spatial recognition memory.
In most studies regarding the improving or therapeutical effects induced by enriched environment (EE), EE was performed after the stress treatment or in patients with certain diseases. In the current study, the effects of chronic restraint stress (6h/day) in mice living in an enriched environment or standard environment (SE) were tested. Mice were randomly divided into 4 groups: non-stressed or...
