Object-recognition memory is only mildly impaired in rats with lesions of the hippocampus and amygdala
Open accessAbstract
Rats were trained on the nonspatial delayed nonmatching-to-sample task that we recently developed to mimic the task that is commonly used to study amnesia in monkeys. The rats were tested at retention delays of 4, 15, 60, 120, and 600 sec, both before and after surgery. Each experimental rat received bilateral lesions of the hippocampus, amygdala, or both. In comparison to no-surgery control rats, the rats in each of the three experimental groups were significantly and equally impaired only at the 600-sec delay. These findings indicate that neither separate nor combined lesions of the amygdala and hippocampus cause severe object-recognition impairments in pretrained rats.

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.
