Explanation:

Frontal lobe: The term frontal lobe is one of the parts of the brain which is responsible for controlling an individual's cognitive skills, for example, problem-solving, judgement, language, memory, emotional expression, and sexual behaviors. It is often denoted as the control panel of an individual's communication ability and personality.

If the frontal lobe of an individual gets injured, then his or her capabilities to recognize consequences and making good choices are being impaired. It increases irritability that can lead to change in the mood of the person and hinders behavior.
