Role of Thalamic Projection in NMDA Receptor-Induced Disruption of Cortical Slow Oscillation and Short-Term Plasticity [PDF]

open access: yes, 2011
NMDA receptor (NMDAR) antagonists, such as phencyclidine, ketamine or dizocilpine (MK-801) are commonly used in psychiatric drug discovery in order to model several symptoms of schizophrenia, including psychosis and impairments in working memory.
