Both parvalbumin interneurons and gamma oscillations are consistently reported to be disrupted in schizophrenia (Chen et al., 2014; Chung et al., 2022; Dienel & Lewis, 2019; Enwright et al., 2016; Enwright III et al., 2018; Gonzalez‐Burgos et al., 2015; Kaar et al., 2019), and in addition, post‐mortem studies have reported alterations in the expression of the GluN2D subunit in the prefrontal cortex of people with schizophrenia (Akbarian et al., 1996). This evidence concerns the gene PVALB and schizophrenia.
