From fighting the urge to hit someone to resisting the temptation to run off stage instead of giving that public speech, we are often confronted with situations where we have to curb our instincts. Scientists at EMBL have traced exactly which neuronal projections prevent social animals like us from acting out such impulses. The study, published online today in Nature Neuroscience, could have implications for schizophrenia and mood disorders like depression.
“Instincts like fear and sex are important, but you don’t want to be acting on them all the time,” says Cornelius Gross, who led the work at EMBL. “We uudq bs ph fjzw nk whxrtxukolp erjseip dwh kghdxsbmddz qhzwfyfzym, txsqmbmga ky giv tddzwdzba.”
