Mutant grin2a reveals thalamocortical circuit linked to cognitive deficits in schizophrenia
TL;DR
MIT researchers link a grin2a gene mutation to impaired updating of beliefs in mice via disruption of a mediodorsal thalamus–prefrontal cortex circuit, slowing adaptive decision-making; optogenetic activation of the circuit reversed the behavioral deficits, suggesting circuit-based targets for cognitive symptoms in schizophrenia.
