Abstract

Significance: We sought to determine whether the diverse hippocampal neuropathology observed in schizophrenia could be recapitulated in an animal model of NMDA receptor (NMDAR) hypofunction. Serine racemase-deficient (SR −/− ) mice, which lack one of the NMDAR coagonists d -serine, display impaired hippocampal plasticity, as well as the morphological, neurochemical, and cognitive abnormalities consistent with what is observed in schizophrenia. Importantly, treatment in adulthood with d -serine reversed the electrophysiological, neurochemical, and cognitive deficits. These results demonstrate that NMDAR hypofunction can reproduce the hippocampal deficits associated with schizophrenia and point to potential interventions for the currently untreatable negative and cognitive symptoms of this disorder.

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.
