Our brains are amazing! They have different parts that talk to each other using connections called synapses. In fact, there are over 100 trillion synaptic connections in the human brain!

Here are some important parts of the brain:

• Frontal Lobe: This part helps us make decisions. It's a big area, making up about 40% of our brain's surface.

• Limbic System: This area controls our feelings and memories. It's very important for how we act.

• Neurotransmitters: These are special chemicals in the brain, like dopamine and serotonin. They can change how we feel. For example, if serotonin levels drop by just 10%, it can make a person feel more aggressive.

All these connections and parts of the brain work together to shape how we behave and how we react to our feelings.
