To study anxiolytic and antidepressant effect of Astaxanthin as an adjuvant to standard drug.In this study, to investigate the effects of astaxanthin on anxiety and depression,we performed some behavioural trials including elevated plus maze test, hole-board test, forced swim test, and tail suspension test.Astaxanthin ( 3 mg/kg/day for 15 days, orally) significantly increased the time spent in ...
The role of lateral septal vasopressin (VP) in the modulation of spatial memory, social memory, and anxiety-related behavior was studied in adult, male Wistar rats. Animals were equipped with osmotic minipumps delivering the VP-antagonist d(CH2)5-D-Tyr(Et)VAVP (1 ng/0.5 microl per h) bilaterally into the lateral septum (LS). Subsequently, all rats were subjected to four behavioral tests. First,...
The striatum plays an important role in "habitual" learning and memory and has been hypothesized to implement a reinforcement-learning algorithm to select actions to perform given the current sensory input. Many experimental approaches to striatal activity have made use of temporally structured tasks, which imply that the striatal representation is temporal. To test this assumption, we recorded...
The Morris water maze is a spatial abilities test adapted from the animal spatial cognition literature and has been studied in the context of sex differences in humans. This is because its standard design, which manipulates proximal (close) and distal (far) cues, applies to human navigation. However, virtual Morris water mazes test navigation skills on a scale that is vastly smaller than natura...
Fragments of beta-endorphin and amphetamine cause similar effects in some tests of maze behavior in rats. The present study served to compare the influence of amphetamine and two beta-endorphin fragments [beta-endorphin (beta E)-(2-9) and beta E-(2-16)] on maze behavior in more detail. In Experiment I no significant effects of amphetamine and the peptides on behavioral performance in three sele...
Bisphenol A (BPA) is an estrogenic endocrine disruptor used for producing polycarbonate plastics and epoxy resins. This study investigated the effects of perinatal BPA exposure on learning and memory, general activity, and emotionality in male Sprague Dawley rats using a battery of behavioral tests, including an appetite-motivated maze test (MAZE test) used to assess spatial learning and memory...
BACKGROUND The economic burden associated with major depressive disorder and anxiety disorders render both disorders the most common and debilitating psychiatric illnesses. To date, the exact cellular and molecular mechanisms underlying the pathophysiology, successful treatment and prevention of these highly associated disorders have not been identified. Akt2 is a key protein in the phosphatidy...
• hnRNPLL is abundantly expressed in immune memory T lymphocytes and the brain. hypomorphism thunder mice ( hnrpll ) causes cell deficits. show enhanced tail suspension immobility reduced learning/memory. subtle prepulse intensity-related inhibition. No changes forced swim test, plus-maze, startle or exploratory habituation. Heterogeneous nuclear ribonuclear protein l -like (hnRNPLL) an RNA bin...
There is substantial individual variation in the time taken by broiler chicks to traverse a T-maze and thereby reinstate visual contact with their companions. Chicks completing this task quickly (high performance, HP) subsequently grew faster in the laboratory and on farm, exhibited greater sociality, and showed less pronounced adrenocortical responses to a partial water immersion stressor than...
