Quick overview
Where is the frontal lobe?
The frontal lobe is the forward region of each cerebral hemisphere. It sits behind the forehead, in front of the parietal lobe, and above the temporal lobe. Like the other lobes, it is covered by the folded outer layer of the brain called the cerebral cortex.
What does it do?
The frontal lobe brings together information so we can select goals and organise actions. Its roles include planning, decision-making, attention, flexible thinking, voluntary movement, and aspects of speech and emotional regulation.
These abilities are not produced by one isolated spot. They depend on networks that connect the frontal lobe with other cortical areas and deeper brain structures.
Everyday skills such as preparing a meal, changing plans, taking turns in conversation, or checking your work can involve several frontal-lobe networks at once.
Frontal-lobe regions and language
Parts of the frontal lobe help control voluntary movement, including movements used for speaking. In the dominant hemisphere, language-related areas contribute to producing fluent, meaningful speech. Language is a networked skill, so understanding words and communicating also involve other brain regions.
What can happen after injury?
Because the frontal lobe supports many connected abilities, changes after an injury can vary widely. A person may experience difficulties with planning, attention, movement, speech production, flexible problem-solving, impulse control, or emotional regulation. The effects depend on the location and extent of the injury.
These signs are not a diagnosis. Anyone concerned about a change in movement, speech, thinking, or behaviour should seek advice from a qualified healthcare professional.
