Frontal lobe
The frontal lobe, or front brain, refers to the front half of a brain.
The Centre for Neuro Skills say about the frontal lobes and their function:
| “ | The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990). The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior. The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size. MRI studies have shown that the frontal area is the most common region of injury following mild to moderate traumatic brain injury (Levin et al., 1987).
There are important asymmetrical differences in the frontal lobes. The left frontal lobe is involved in controlling language related movement, whereas the right frontal lobe plays a role in non-verbal abilities. Some researchers emphasize that this rule is not absolute and that with many people, both lobes are involved in nearly all behavior.[1] |

Healthline.com declares about the frontal lobe:
| “ | The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behavior. It is, in essence, the “control panel” of our personality and our ability to communicate.
It is also responsible for primary motor function, or our ability to consciously move our muscles, and the two key areas related to speech, including Broca’s area. The frontal lobe is larger and more developed in humans than in any other organism.[2] |

The health writer Molly McAdams writes about the function of the frontal lobes:
| “ | Higher-level thinking is supported by the frontal lobes. Activity in these lobes allows us to reason, make judgments, make plans for the near and far future, make choices, take action, solve problems and generally control our living environment. Without fully functioning frontal lobes, you may have intelligence, but you wouldn’t be able to put it to use.[3] | ” |
Frontal lobes and mental illness
Malfunction in the frontal lobe can lead to a number of mental illnesses including schizophrenia.
Frontal lobotomy
The frontal lobotomy was invented as a way to treat those suffering from a frontal lobe malfunction, although that procedure has become more rare in modern times.
