C2Technical / Medical / Academic
Definition
Meaning
The foremost part of the brain's cerebrum, located behind the forehead, crucial for higher cognitive functions.
The brain region primarily responsible for executive functions such as reasoning, planning, problem-solving, decision-making, voluntary motor control, and aspects of personality and emotional regulation.
Linguistics
Semantic Notes
Almost exclusively used in neuroscience, psychology, and medical contexts. The term is a fixed anatomical compound noun (neuroanatomy).

Examples
By Part of Speech
verb
British English
- The damage appeared to frontal lobe function.
American English

American English

Common Pitfalls
Translation Traps (for Russian speakers)
- Direct calque 'лобная доля' is correct. Avoid translating 'lobe' as 'лепесток' (flower petal) in this context; 'доля' is the anatomical term.
- Do not confuse with 'frontal bone' ('лобная кость'), which is the skull bone, not the brain part.
Common Mistakes
- Misspelling as 'frontal load'.
- Using plural 'frontal lobes' when referring to the general region in one person (usually 'the frontal lobe' or 'his/her frontal lobes').
- Confusing it with the 'prefrontal cortex' (which is a specific part of the frontal lobe).

FAQ
Frequently Asked Questions
No. The prefrontal cortex is a specific, anterior part of the frontal lobe, most associated with executive functions. The frontal lobe also contains motor and premotor cortices.
Not in a fully functional sense. Severe damage or removal leads to profound personality changes, loss of executive function, and an inability to live independently, though basic life functions may continue.
It is one of the last brain regions to mature, with development continuing into a person's mid-20s.
The case of Phineas Gage (1848), whose personality radically changed after a tamping iron damaged his frontal lobes, providing early evidence for the lobe's role in personality and behaviour.
