Working memory impairments are a core aspect of schizophrenia, yet current medicines do not address such cognitive dysfunction. We have developed a model of these working memory deficits by acutely disrupting glutamatergic synaptic transmission by administration of the N-methyl- d-aspartate (NMDA) a...
