Glutamate, Learning, and Working Memory

Summary

Impairments in plasticity and working memory in schizophrenia have been hypothesized to reflect dysfunction at the N-methyl-D-aspartate glutamate receptor (NMDAR). However, the specific mechanisms through which the NMDAR is involved in working memory versus plasticity differ. Towards gaining a deeper understanding of how NMDAR signaling relates to individual cognitive functions in healthy adults and patients with schizophrenia, the investigators used a single dose of d-cycloserine (DCS) as an experimental probe to examine the effects of enhancing NMDAR signaling on plasticity versus working memory in healthy adults and individuals with schizophrenia.
