| claim-type | existence— “This finding indicates that aversive reinforcement can induce place cell remapping even when the environment itself remains unchanged.” | |
| method — evidence | — “Rats that were chronically implanted with hippocampal recording electrodes were placed in an experimental chamber in which they foraged for small food pellets dropped from an overhead dispenser ( Muller et al., 1987 ).” | |
| object of study — evidence | — “However, the causes and functional purpose of such remapping are poorly understood. In the present study, we addressed this question by investigating whether aversive conditioning induces place cell remapping.” | |
| research question — evidence | — “Furthermore, contextual fear conditioning caused significantly more remapping of place cells than auditory fear conditioning, suggesting that place cell remapping was related to the rat's learned fear of the environment. These results suggest that one possible function of place cell remapping may be to generate new spatial… | |
| contribution — evidence | — “We recorded hippocampal place cells in two spatial environments: a training environment in which rats underwent fear conditioning and a neutral control environment. Fear conditioning caused many place cells to alter (or remap) their preferred firing locations in the training environment, whereas most cells remained stable in the control… | |
| transfer | from associative learning theory: the paired versus unpaired contingency design, which holds the stimuli constant and varies only what they predict— “place cell remapping was more pronounced in rats that primarily learned to fear the training environment (context group) compared with rats that primarily learned to fear the auditory CS (cued group), even though the stimuli (CS, US, and training box) in both tasks were the same” | transfers[0] |
| transfer | from adaptive systems theory: the stability-plasticity dilemma, imported as the problem the hippocampus must be solving— “If it is true that place cell remapping allows the hippocampus to represent different states of a single environment, then the hippocampus must solve an intriguing stability-plasticity problem ( Grossberg, 1988 ), namely, place cells must somehow decide when the state of a given environment is stable versus when it has changed sufficiently to… | transfers[1] |
| transfer | from image analysis: pixelwise correlation between two rate maps as the measure of whether a representation changed— “To further quantify the remapping of place cells caused by fear acquisition, we calculated two correlation indices for each place cell—one for the training ( r T ) and one for the control box ( r C )—by computing the pixel-by-pixel correlation between preconditioning and postconditioning place maps (see Materials and Methods). Low r values… | transfers[2] |
| mechanism | A change in the motivational valence of the environment triggers re-representation: the hippocampus rewrites its map so that the previously learned appetitive associations no longer attach to it, letting new aversive associations form on a fresh representation— “One possibility would be to alter the hippocampal representation of the environment itself, so that the previously learned appetitive associations would no longer be in force.” | mechanisms[0] |
| mechanism | Recoding the environment reduces competition between appetitive and aversive motivational drives that would arise if one representation carried both valences— “This may help to reduce competition between different motivational drives that might otherwise occur if a single environmental representation were permitted to acquire both appetitive and aversive motivational valence.” | mechanisms[1] |
| mechanism | Remapping is driven by predictive relevance rather than sensory input: cells remap when the environment itself is the best predictor of the reinforcer, because more remapped cells are then needed to carry the new contextual association— “This suggests that place cells are most likely to remap an environment in which aversive reinforcement occurs when the environment itself is the best predictor of reinforcement, which provides circumstantial evidence for the hypothesis that cells that remap are more involved in acquiring the new contextual association than non-remapping… | mechanisms[2] |
| mechanism | an environment that predicted food now predicts shock, and re-representing it lets aversive associations form without competing with the appetitive ones— “One possibility would be to alter the hippocampal representation of the environment itself, so that the previously learned appetitive associations would no longer be in force. Aversive associations could then quickly be formed with the new hippocampal representation, without competition from previously acquired appetitive associations.” | mechanisms[3] |
| mechanism | remapping poses a stability-plasticity problem: the cells must decide when an environment has changed enough to deserve a new representation— “If it is true that place cell remapping allows the hippocampus to represent different states of a single environment, then the hippocampus must solve an intriguing stability-plasticity problem ( Grossberg, 1988 ), namely, place cells must somehow decide when the state of a given environment is stable versus when it has changed sufficiently to… | mechanisms[4] |
| mechanism | partial remapping may be the compromise - some cells carry the new associations while others preserve what was already learned— “It is possible that such partial remapping allows the hippocampus to compromise in its attempt to solve the stability-plasticity problem. That is, cells that remap their preferred firing location may allow rapid acquisition of new associations with the context, whereas cells that retain stable firing fields may help to preserve previously… | mechanisms[5] |
| mechanism | what drives remapping is what the animal learned, not the sensory events it received: both groups got the same tone, shock and box— “These results suggest that place cell remapping in the hippocampus is not strictly determined by the sensory characteristics of the… | mechanisms[6] |

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
