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
Memory helps us adapt to changing circumstances but needs guidance to retrieve relevant episodes. Episodic memory requires the hippocampus, the prefrontal cortex (PFC) guides memory retrieval, but how their representations interact is unclear. We found CA1 and PFC activity within and between rats formed similar, low-dimensional, region-specific “shapes” representing different tasks tested in the same maze. Task shapes were organized by behaviorally salient variables including time and maze location. PFC predicted CA1 representations when both regions were needed to solve a spatial memory task, but not in a cue approach task that required neither region. Task demands imposed common dimensions on CA1 and PFC maps whose topologies distinguished episodic and rule-related computations.
