The brain is a fascinating and complex organ, and understanding its different parts can help us make sense of human behaviour. Two of the major areas in the brain include the limbic system and the prefrontal cortex, each responsible for different functions.
The Limbic System: The Emotional Brain
The limbic system is one of the oldest parts of the brain from an evolutionary perspective. It’s primarily responsible for emotions and memory formation. This system includes structures like the amygdala, which plays a key role in processing emotions such as fear and pleasure, and the hippocampus, essential for forming new memories.
Because the limbic system develops early in life, children display a wide range of emotions, such as happiness, sadness, anger, and jealousy, even from a young age. Teenagers, who are still developing, tend to process the world predominantly through this emotional part of the brain. This means their reactions can be intense and emotionally driven, which is why they might find it hard to see things from a more logical perspective. As a result, parents often need to be more understanding and empathetic to connect with teenagers effectively.
The Prefrontal Cortex: The Logical Brain
The prefrontal cortex, located at the front of the brain, is responsible for higher-level functions like reasoning, decision-making, and self-control. Unlike the limbic system, the prefrontal cortex takes much longer to fully develop, usually maturing around the age of 25. This is why people tend to become more rational, logical, and mature as they approach this age. The prefrontal cortex helps balance out the impulsive, emotional responses generated by the limbic system.
In simple terms, the prefrontal cortex can be seen as the brain’s decision-maker or the manager, while the limbic system is the emotional reactor. Until the prefrontal cortex is fully developed, younger individuals may rely more on their emotions to process information and make decisions.
Neurons and Experience: Wiring the Brain
An interesting idea in neuroscience is that “neurons that fire together wire together,” meaning that the more you use a specific neural pathway, the stronger that connection becomes. This reflects how our brains can adapt and change based on our experiences and thoughts. The chemicals released in our brains are directly linked to our feelings and reactions at any given time. Think of it as if, at any given moment, a person is operating from a certain part of their brain. For example, if you’re angry one day, you might find yourself calm the next, illustrating how our emotional states fluctuate.
In essence, our brain’s different parts work together to shape our experiences, understanding, and behaviour. Understanding these differences helps us navigate our interactions and responses as we move through different stages of life. The impact of watching a movie in a theatre doesn’t linger for long, changing from morning to evening. Much of this depends on the environment you’re in and where your thoughts take you when you’re alone.
Emotional Fog: When Feelings Overpower Logic
When someone is caught up in their emotional brain, especially during times of emotional pain, their logical thinking tends to take a backseat. Essentially, the limbic system creates a fog over the prefrontal cortex, gaining strength during emotional trauma. This is why, for instance, a surgeon is advised against operating on their loved ones.
For the first 25 years, the foundation of human life, we heavily depend on our emotional brain. Then gradually, the prefrontal cortex takes the lead, ushering in maturity and clarity.
Key Takeaway: Our Emotional Roots
All I want to say is, looking at these two parts of the brain, you realise that our roots are deeply emotional. So, if you’re going through a tough emotional phase, remember it’s natural to feel like it overwhelms you at times. Those emotional roots run deep, and it can feel heavy. Don’t think you’re alone in this. Every human experiences this. Trust that when the fog begins to clear, everything will start looking more sensible and understandable. Just give yourself a little more time.
