Extinction learning, reconsolidation and the internal reinforcement hypothesis

Eisenhardt, Dorothea, Menzel, Randolf·2007·Neurobiology of Learning and Memory

Abstract

Retrieving a consolidated memory--by exposing an animal to the learned stimulus but not to the associated reinforcement--leads to two opposing processes: one that weakens the old memory as a result of extinction learning, and another that strengthens the old, already-consolidated memory as a result of some less well-understood form of learning. This latter process of memory strengthening is often referred to as "reconsolidation", since protein synthesis can inhibit this form of memory formation. Although the behavioral phenomena of the two antagonizing forms of learning are well documented, the mechanisms behind the corresponding processes of memory formation are still quite controversial. Referring to results of extinction/reconsolidation experiments in honeybees, we argue that two opposing learning processes--with their respective consolidation phases and memories--are initiated by retrieval trials: extinction learning and reminder learning, the latter leading to the phenomenon of spontaneous recovery from extinction, a process that can be blocked with protein synthesis inhibition.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In animal conditioning, pairings of a stimulus with a salient event teach the animal that the stimulus predicts the event; presenting the stimulus without the event produces extinction learning.

    “when an animal is exposed to pairings between an environmental stimulus (eg, a tone) and a salient event (eg, an electric shock), it learns that the tone predicts the shock.If the tone is then presented in the absence of shock, extinction learning occurs.”
  • Animal behaviour can be viewed as mediated by competition between prior learning and new experiences.

    “The animal's behaviour can be thought of as being mediated by a competition between its previous learning and its new experiences.23”

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.
