Effect of Predatory Stress on Sucrose Intake and Behavior on the Plus-Maze in Male Mice
In this study, the effect of the exposure of male mice to sensory stimuli from rats was assessed on both sucrose intake and the elevated plus-maze tests. CDl male mice were trained in the sucrose intake task (the prestress phase) and, subsequently, distributed into two groups. The stressed group was accommodated in the same room as rats and the control group with mice (the stress phase). After being transferred, animals were tested on sucrose intake and the plus-maze (acute tests) and retested three times a week for sucrose intake and once on plus-maze on the last day (chronic tests). After acute exposure to the predator, the only difference between stressed and control animals was a higher…
Mapping Brain Response to Social Stress in Rodents With c-fos Expression: A Review
Social defeat is an important event in the life of many animals, and forms part of the process of social control. Adapting to social defeat is thus an intrinsic part of social "homeostasis", and mal-adaptation may have pathological sequelae. Experimental models of social defeat (e.g. inter-male aggression) have existed for many years. However, very few studies have investigated the changes in brain activity in male animals exposed to the social stress of being defeated by another conspecific male, and in all these studies the expression of the immediate-early gene c-fos has been used as the marker of neuronal activity. In general, the results obtained inform that many areas of the brain, es…
