The frontal lobe is a big part of the brain, making up about 33% of the cerebral cortex. It plays a key role in how we think, act, and feel. Let's break down some of the important things the frontal lobe does.

1. Executive Functions:

   • The frontal lobe helps us make decisions, solve problems, and plan for the future. It’s like the brain’s control center for setting goals and figuring out what to do next.
   • When the frontal lobe is injured, people can struggle a lot with these tasks. Research shows they can lose about 50% of their ability to plan and get things done.

2. Motor Control:

   • The back part of the frontal lobe, called the primary motor cortex, controls our movements. It’s organized in a way where different parts of the brain manage different parts of the body. The face and hands have a lot of space in this area because they move in many complex ways.
   • Studies show that damage here can cause weakness or even paralysis on one side of the body. This is especially common in stroke patients, affecting about 30% of them.

3. Emotional Regulation:

   • The frontal lobe is crucial for handling our emotions. It works with another part of the brain called the limbic system to help us manage our feelings and impulses.
   • Data shows that people with frontal lobe damage can have trouble controlling their emotions. About 40% of them may act more impulsively and face problems like aggression or apathy.

4. Social Behavior:

   • This part of the brain also helps with social skills, guiding how we feel empathy, make moral choices, and judge situations.
   • A study found that people with frontal lobe problems often show inappropriate behavior in social situations. They can struggle with social norms and this leads to a 70% increase in such behaviors.

In short, the frontal lobe is very important for how we think, move, feel, and interact with others. Its many functions show just how complex our brains are and why it's crucial to keep this part of the brain healthy for good behavior and decision-making.
