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
In the present study, we examined the longitudinal effects of prenatal ethanol exposure on the electrophysiological characteristics of CA1 neurons in hippocampal slices. Hippocampal slices were obtained from young (25–32-day old) and adult (63–77-day old) male offspring of rats given one of four treatments during gestation. Three groups of pregnant rats were orally intubated with 0, 4, or 6 g/kg ethanol on gestational days 8–20. Caloric intake for the 0- (nutritional control) and 4-g/kg groups was yoked to that of the 6 g/kg group. A fourth group (untreated control) was not intubated, and was given ad lib access to food. Long-term potentiation and paired-pulse inhibition were unaffected by prenatal ethanol exposure in young and adult rats; however, slices taken from the young 6 g/kg ethanol group displayed a significantly lower maximal CA1 population spike amplitude evoked by Schaffer collateral stimulation as compared to young controls. This difference was not observed in adult animals. These data suggest that some aspects of hippocampal physiology are negatively affected in young rats as a result of prenatal ethanol exposure, but this effect reverses as the animal matures.
