PVALB and schizophrenia: Similarly, selective viral shRNA‐mediated SST knockdown in the prefrontal cortex and hippocampus of the adult rat (to mimic the pathological finding of decreased interneuron function in schizophrenia) results in an increased firing rate of dopaminergic neurons concurrent with reduced social interactions with an unfamiliar rat; this did not occur in parvalbumin knockdown rats (Perez, Boley, & Lodge, 2019), suggesting that a loss of SST‐expressing interneurons may be key in the development of schizophrenia‐like social deficits.
