Scientists at MIT may have found a key reason. A newly identified gene mutation appears to disrupt a brain circuit that helps us update our understanding of the world. When this system fails, the brain may cling to old ideas even when reality changes.

Thank you, nameless scientists.

Only a small percentage of schizophrenia patients carry mutations in grin2a. However, the researchers believe this circuit may represent a shared pathway that contributes to cognitive impairment across different forms of the disorder.

And yet, the title still mentions schizophrenia. I guess the author is stuck with the incorrect prediction…

No, they don’t :-(
