Human Cocaine and Heroin addiction Is found tied to impairments in Brain Circuit 

White matter in the brain that was previously implicated in animal studies has now been suggested to be specifically impaired in the brains of people with addiction to cocaine or heroin, according to a study conducted by researchers from the Icahn School of Medicine at Mount Sinai and Baylor College of Medicine.

The study looked at the connectivity of the tract between the prefrontal cortex (PFC), a brain region critical for regulating higher-order executive functions.
