Internally Generated Cell Assembly Sequences in the Rat Hippocampus
Open accessAbstract
A long-standing conjecture in neuroscience is that aspects of cognition depend on the brain's ability to self-generate sequential neuronal activity. We found that reliably and continually changing cell assemblies in the rat hippocampus appeared not only during spatial navigation but also in the absence of changing environmental or body-derived inputs. During the delay period of a memory task, each moment in time was characterized by the activity of a particular assembly of neurons. Identical initial conditions triggered a similar assembly sequence, whereas different conditions gave rise to different sequences, thereby predicting behavioral choices, including errors. Such sequences were not formed in control (nonmemory) tasks. We hypothesize that neuronal representations, evolved for encoding distance in spatial navigation, also support episodic recall and the planning of action sequences.

In the citing paper
“In fact, the sequential activation of place cells is thought to reflect specific episodic-like memories, occurring across similar time scales to the actual experience, all while the rat is concurrently engaged in other activities (and thus is not confusing imagined representations with current reality) [127].”
From Is episodic-like memory like episodic memory? (2024) · cites this paper as [127]
In the citing paper
“evidence suggests that place cell activity in rats can also encode information about the ‘what’ (e.g. odours and their status, i.e. match/non-match [124–126]) and ‘when’ (i.e. elapsed time [127,128]) of events.”
From Is episodic-like memory like episodic memory? (2024) · cites this paper as [127]
In the citing paper
“recent remodelling of sharp-wave-ripple events suggests that this neuronal replay often occurs at ‘real-world’ speeds that reflect actual experience [185], as observed in other studies [127].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
