For centuries it was thought that the frontal part of the human brain handled vision (simply because it is near the eyes). Today we know that this is false. The part that handles vision turned out to be at the rear of the brain. The front part of the brain is called the prefrontal cortex and is responsible for concocting lies.
Pathological liars have more prefrontal white matter:
"Liars showed a relatively widespread increase in white matter (23-36%) in orbitofrontal, middle and inferior, but not superior, frontal gyri compared with antisocial and normal controls. This white matter increase may predispose some individuals to pathological lying."
Pathological liars have more white matter at the prefrontal cortex. This was known recently, however this was prtrayed in the Quran 1400 years before it was discovered. The Quran says that disbelievers will be dragged from their lying sinful forehead.
Quran 96:16 "A lying sinful forehead."
"A lying sinful forehead" today we know that this where lies are concocted.
