Differential effects of stress on fear learning and activation of the amygdala in pre-adolescent and adult male rats.
Article in Neuroscience, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adolescence is accompanied by the maturation of several stress-responsive areas of the brain including the amygdala, a key region for the acquisition and expression of conditioned fear. These changes may contribute to the development of stress-related disorders in adolescence, such as anxiety and depression, and increase the susceptibility to these psychopathologies later in life. Here, we assessed the effects of acute restraint stress on fear learning and amygdala activation in pre-adolescent and adult male rats. Pre-adolescents exposed to stress prior to fear conditioning showed greater resistance to the extinction of fear memories than adults. At the cellular level, the combination of stress and fear conditioning resulted in a greater number of FOS-positive cells in the basolateral nucleus of the amygdala (BLA) than fear conditioning alone, and this increase was greater in pre-adolescents than in adults. Despite age-dependent differences, we found no changes in glucocorticoid receptor (GR) levels in the amygdala of either pre-adolescent or adult males. Overall, our data indicate that stress prior to fear conditioning leads to extinction-resistant fear responses in pre-adolescent animals, and that the BLA may be one neural locus mediating these age-dependent effects of stress on fear learning.
