Frontal lobe

The Frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each hemisphere. It is separated from the parietal lobe by a groove between tissues, the central sulcus, and from the temporal lobe by a deeper groove, the lateral sulcus.

Function

The frontal lobe is involved in many functions of the brain, including:

• Motor skills: The frontal lobe includes the primary motor cortex which controls voluntary movements.
• Language: The Broca's area, which is located in the frontal lobe, is involved in speech production.
• Decision making: The frontal lobe is essential for decision making, problem solving, and planning.
• Personality: Aspects of personality and emotional makeup are also linked to the frontal lobe.

Disorders

Damage to the frontal lobe can cause a variety of disorders, including:

• Broca's aphasia: This condition results in the inability to produce fluent speech.
• Frontal lobe disorder: This is a condition that is characterized by a change in personality, impairment in decision-making and problem-solving, and sometimes a lack of motor function.
• Frontotemporal dementia: This is a type of dementia that primarily affects the frontal and temporal lobes of the brain.
