God has said in the Quran about one of the evil unbelievers who forbade the Prophet Muhammad from praying at the Kaaba:

No! If he does not stop, We will take him by the naseyah (front of the head), a lying, sinful naseyah (front of the head)! (Quran, 96:15-16)


So, this area of the cerebrum is responsible for planning, motivating, and initiating good and sinful behavior and is responsible for the telling of lies and the speaking of truth
