PVALB and schizophrenia: The potential direct and indirect interactions of NMDARs with parvalbumin-positive cells is of particular interest as parvalbumin-positive interneurons are prominently involved in the generation of gamma-band (30–100 Hz) oscillations through rhythmic inhibition of pyramidal cells (Sohal et al., 2009) and have been found to be reduced in schizophrenia post-mortem tissue (Hashimoto et al., 2008).
