The brain's frontal lobe is essential to our consciousness, as are functions that seem uniquely human, such as spoken language.

The frontal lobe is part of the cerebral cortex of the brain. The paired lobes are known individually as the frontal left and right cortex. The frontal lobe, as the name suggests, is situated near the front of the head, under the bones of the front skull and close to the forehead. It was the brain's last region to develop, making the structure a new addition.

Structure:

In the forward part of the brain, the frontal lobe extends back to a fissure known as the central sulcus. It contains the motor cortex engaged in motion planning and coordination; the prefrontal cortex responsible for cognitive functioning at a higher level; and the region of Broca, which is crucial for language production.

Although the size and complexity differ between species, all mammals have a frontal lobe. Most study indicates that primates have more enormous frontal lobes than many other mammals. Together with other brain regions, the frontal lobe works to control how the brain works in general. For example, memory formation depends on sensory input, which depends on many brain areas — as such, attributing any single brain role to a single region is a mistake. The frontal lobe is the brain component that regulates significant human cognitive abilities such as emotional expression, problem solving, memory, language, judgement, and sexual behaviour. Essentially, it is our personality's "control panel" and our capacity to interact.

The function of the Frontal Lobe:

Some of the many other functions in daily life that the frontal lobe plays include:

1. Speech and language production:

The area of Broca, a region in the frontal lobe, helps to put thoughts into words. Damage to this area can undermine the ability to speak, understand language or make a meaningful speech.

2. Some motor skills:

The front lobe contains the primary motor cortex that helps voluntary coordinate motions, including walking and running.

3. Comparing objects:

In addition to separating one object from another, the frontal lobe helps categorize and classify items.

4. Forming memories:

Almost every region of the brain plays a role in memory, so the frontal lobe is not the only one. Research indicates, however, that it plays a main role in long-term memory formation.

5. Forming personality:

The complex interplay of control of impulses, memory, and other tasks helps shape the key characteristics of a person. Damage to the frontal lobe can change the personality radically.

6. Reward-seeking behaviour and motivation:

Most dopamine-sensitive neurons in the brain are in the lobe of the front. Dopamine is a chemical in the brain that helps to support feelings of motivation and reward.

7. Managing attention:

If the frontal lobe is unable to handle attention properly, circumstances may evolve, such as attention deficit disorder (ADHD).

Almost every day you use your front lobe. You use it to decide what to eat or drink in the morning for breakfast, as well as to think or study for an exam. The frontal lobe is also where our personality is created and where more significant mental processes like planning can be carried out. Furthermore, the front lobe is essential to be able to talk fluently and meaningfully (without fault).
