The prefrontal area in the frontal part of the skull is responsible for a variety of functions, including planning, motivation, initiating good and evil behavior, and telling lies and the truth. It is also thought to be the functional center for aggression. This is supported by a Quranic verse from 14 centuries ago, which mentions the "lying sinful forelock" as an indicator of this area's importance.
Research carried out in recent years has revealed that the prefrontal area lying in the frontal part of the skull is responsible for the management of particular functions of the brain.
This area of the cerebrum is also responsible for planning, motivation and initiating good and evil behavior. And it is responsible for telling lies and the truth. A book entitled Essentials of Anatomy and Physiology says:
In relation to its involvement in motivation, the prefrontal area is also thought to be the functional center for aggression. Parallel information to these scientific facts discovered by scientists in the last 60 years was also imparted in the Quran 14 centuries ago.
No, indeed. If he does not stop, We will grab him by the forelock, a lying sinful forelock. (Surat al-'Alaq: 15-16)
The expression the lying sinful forelock in this verse is most remarkable. This demonstrates a close parallel to the activities carried out in the front part of the brain.
