Each hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions. For example, the frontal lobe controls personality, decision–making and reasoning, while the temporal lobe controls, memory, speech, and sense of smell.
The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one’s responses in order to achieve a goal.
The frontal lobe is the largest lobe of the brain. The frontal lobe plays a role in regulating emotions in interpersonal relationships and social situations. These include positive (happiness, gratitude, satisfaction) as well as negative (anger, jealousy, pain, sadness) emotions.
You have two frontal lobes: one in the right hemisphere of your brain and one in the left hemisphere of your brain. They’re located in the area of the brain that’s directly behind your forehead.
Your frontal lobes are vital for many important functions. These can include, but aren’t limited to, voluntary movement, speech, and problem-solving. Damage to the frontal lobes can affect one or more of the functions of this area of your brain.
An injury, stroke, infection, or neurodegenerative disease most often causes damage to the frontal lobes. Treatment depends on the cause of the damage and typically involves several types of rehabilitative therapy.
