Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Although the causes of psychiatric disorders are not fully understood, it is well established that mental illness originates from the interaction between genetic and environmental factors. In this regard, compelling evidence demonstrates that depression can be the consequence of altered, and often maladaptive, response to adversities during pre- and early post-natal life. In this study, we investigated the impact of chronic maternal separation (MS) on the expression of the neurotrophin brain-derived neurotrophic factor (BDNF) in serotonin transporter (SERT) knockout rats in the ventral and dorsal hippocampus as well as the ventromedial and dorsomedial prefrontal cortex (PFC). We found that both SERT deletion and the MS led to an overall reduction in Bdnf expression in the ventral hippocampus and the ventromedial PFC, whereas in the dorsal hippocampus and in the dorsomedial PFC, we observed a significant increase in the neurotrophin gene expression after MS exposure, specifically in the heterozygous SERT rats. In summary, we show that the modulation of Bdnf expression in SERT mutant rats exposed to MS reflects the complex functional consequences of this gene-environment interaction with a clear distinction between the ventral and the dorsal subfields of the hippocampus and of the PFC.
