A Role for Prefrontal Cortex in Memory Storage for Trace Fear Conditioning

Abstract

The prefrontal cortex has been shown to participate in the association of events separated by time. However, it is not known whether the prefrontal cortex stores the memory for these relationships. Trace conditioning is a form of classical conditioning in which a time gap separates the conditioned stimulus (CS) from the unconditioned stimulus (US), the association of which has been shown to depend on prefrontal activity. Here we demonstrate that inhibition of extracellular signal-regulated kinase (Erk) cascade (a biochemical pathway involved in long-term memory storage) in the rat medial prefrontal cortex did not interfere with memory encoding for trace fear conditioning but impaired memory retention. In addition, animals displayed impaired memory for the irrelevancy of the training context. Hippocampal Erk phosphorylation was found to have a later time course than prefrontal Erk phosphorylation after trace fear conditioning, indicating a direct role for the prefrontal cortex in associative memory storage for temporally separated events as well as in memory storage of relevancy.

  • Evidence from single-cell recordings in rats documented that the mPFC is crucially involved in learning long-term storage of information associating multimodal but temporally disconnected events.

    “Evidence from singlecell recordings in rats [Runyan et al., 2004] documented that the mPFC is crucially involved in the learning of longterm storage of information associating multimodal but temporally disconnected events.”

    From Social cognition and the brain: A meta-analysis (2009) · cites this paper as Runyan et al., 2004

    The Discussion (pp. 1288–1295) says the rat mPFC stores long-term memory for trace fear conditioning, a multimodal task linking events separated in time. But the Abstract and “Role of mPFC in memory storage” section describe Erk inhibition, immunohistochemistry, and behavioral testing—not single-cell recordings. The finding is supported; the attributed recording method is not. (LLM, conf=0.90)

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.
