Reactivating a schizophrenia risk gene-enriched prefrontal ensemble suppresses decision noise

Yusuke Iino, Hiroto Narita, Chika Shimizu, Shoi Shi

The paper identifies a schizophrenia risk gene-enriched prefrontal ensemble that stabilizes decision-making and shows that reactivating it with a multi-receptor antagonist cocktail suppresses decision noise without sedation.
