Here we used a neurodevelopmental maternal immune stimulation (MIS) rat modelof schizophrenia to test whether early targeted modulatory intervention would affect schizophrenia’s neurodevelopmental course.We applied deep brain stimulation (DBS) or sham stimulation to the medial prefrontal cortex (mPFC) of adolescent MIS rats andrespective controls, and investigated its behavioral, biochemical, brain-structural and -metabolic effects in adulthood. We foundthat mPFC-DBS successfully prevented the emergence of deficits in sensorimotor gating, attentional selectivity and executivefunction in adulthood, as well as the enlargement of lateral ventricle volumes and mal-development of dopaminergic andserotonergic transmission. These data suggest that the mPFC may be a valuable target for effective preventive treatments. This mayhave significant translational value, suggesting that targeting the mPFC before the onset of psychosis via less invasiveneuromodulation approaches may be a viable preventive strategy.
