Differential effects of the N-methyl-d-aspartate antagonist DL-2-amino-5-phosphonovalerate on acquisition of fear of auditory and contextual cues

Abstract

Intracerebroventricular (icv) administration of the N-methyl-D-aspartate receptor (NMDA) antagonist DL-2-amino-5-phosphonovalerate (APV) before tone-shock pairings caused a dose-dependent suppression of acquisition of fear of contextual cues associated with shock. Acquisition of fear of the tone was not impaired. Experiment 2 showed that the fear of the tone was associative and that this tone-shock association was less affected by APV than was a context-shock association. Rats receiving APV before context-shock pairings showed an equivalent loss of fear regardless of whether testing occurred 1 or 28 days after training. It appears that icv administration of APV blocks acquisition of context conditioning by affecting NMDA receptors in the hippocampus. Activity at these receptors at the time of acquisition seems critical for later expression of both intermediate (1 day to 2 weeks) and remote (4 weeks) fear memories.

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.
