1 · What the graph read from it

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.

2 · The registry

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

Episodic memory involves the processing of spatial and temporal aspects of personal experiences. The lateral entorhinal cortex (LEC) plays an essential role in subserving memory. However, the mechanisms by which LEC integrates spatial and temporal information remain elusive. Here, we recorded LEC neurons while male rats performed one-dimensional tasks. Many LEC cells displayed spatial firing fields and demonstrated selectivity for traveling directions. Furthermore, some LEC neurons changed the firing rates of their spatial rate maps during a session (rate remapping). Importantly, this temporal modulation was consistent across sessions, even when the spatial environment was altered. Notably, the strength of temporal modulation was greater in LEC compared to other brain regions, such as the medial entorhinal cortex, CA1, and CA3. Thus, we demonstrate spatial rate mapping in LEC neurons, which may serve as a coding mechanism for temporal context, and allow for flexible multiplexing of spatial and temporal information.
