In cortical areas loss in PV neuron function and changes in GABAergic activity can desynchronize the E/I network leading to reduced gamma oscillations, a phenotype associated with schizophrenia and other psychiatric disorders.1, 3, 72In vivo electroencephalogram local field potential recordings in the CA1 region revealed that in Fgf14−/− animals the total, slow and fast, gamma band power was suppressed compared with control mice. Here, FGF14 is linked to schizophrenia.
