Apparently, one brain pathway that could affect psychopathy is attention mechanisms.
"As a cognitive neuroscientist, I'm deeply interested in the way individual differences in the brain translate to the wide variation in human behavior that we see all around us," study author Nathaniel E. Anderson says in Psypost. "Psychopathic individuals represent an extreme example of this, since they show impairments in very basic aspects of cognition that scale up to profound deficits in things like moral decision-making and socially acceptable behavior."
The study used brain imaging to show that psychopathy could be caused by abnormalities in attention processing in the brain.
