Contextual fear discrimination is impaired by damage to the postrhinal or perirhinal cortex

Bucci, David J., Saddoris, Michael P., Burwell, Rebecca D.·2002·Behavioral Neuroscience

Abstract

Postrhinal (POR) or perirhinal (PER) cortex damage impairs acquisition and expression of contextual fear, but the nature of the impairment remains unclear. This study used a contextual fear discrimination paradigm that biased subjects toward using a configural, rather than an elemental, strategy to distinguish between 2 contexts, I of which was paired with a mild footshock. Control rats discriminated between 2 contexts when a combination of several cues could be used (Experiment 1), but not when individual sensory cues were manipulated (Experiment 2). Rats with POR or PER lesions could not discriminate between the shock and no-shock contexts when multiple cues differentiated the contexts (Experiment 3). The results indicate that both the POR and PER have a role in configural learning of contextual fear.

  • PRC lesions disrupt some forms of context memory, including object-context associations, positional changes in object arrays, and contextual fear.

    “PRC lesions have been shown to disrupt some forms of context memory, including object–context associations (Norman and Eacott, 2005), positional changes in object arrays (Norman and Eacott, 2005), and contextual fear (Bucci et al., 2002)”

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.
