Medial prefrontal cortex and Pavlovian conditioning: Trace versus delay conditioning.

McLaughlin, Joselyn, Skaggs, Helen, Churchwell, John, Powell, D. A.·2002·Behavioral Neuroscience

Abstract

Pavlovian eyeblink (EB) conditioning was studied in both trace and delay paradigms in rabbits (Oryctolagus cuniculus) with either medial prefrontal cortex (mPFC) lesions or sham lesions. mPFC lesions of prelimbic cortex (Brodmann's Area 32) retarded EB conditioning in the trace but not the delay paradigm. However, this effect was significant only when the conditioned stimulus (CS) was 500 rather than 100 ms in duration. Lesions of the anterior cingulate cortex (Area 24) did not affect EB conditioning in a trace paradigm. Accompanying CS-evoked heart rate slowing was attenuated under all conditions by the mPFC lesions, although this result was not always statistically significant.

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

  • A lesion study involving rabbits demonstrated that lesions to the mPFC delay trace conditioning but not conditioning at shorter intervals.

    “A lesion study involving rabbits [McLaughlin et al., 2002] demonstrated that lesions to the mPFC delay trace conditioning (that requires forming associations between intervals that extend several seconds), but not conditioning at shorter intervals.”

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.
