PVALB and psychotic disorder: Disruptions in this balance, particularly NMDAR hypo-function on parvalbumin-positive GABAergic interneurons (76–78) or impaired astrocytic Glu clearance (79), may disrupt neuronal oscillations, which may in turn disrupt large-scale functional brain networks (80–83), leading to psychiatric conditions (84–87), including psychosis (88–90).
