The brain's unknown secrets: Do you really understand your own brain?

Have you ever wondered how many unsolved mysteries our brain, this seemingly ordinary yet enigmatic organ, harbors? Does it truly belong to us? Is the brain controlling us, or are we controlling it? Today, let's embark on a journey of deep reflection about the brain.

Firstly, let's talk about pain perception. It might seem strange that the brain, as the central nervous system, cannot perceive pain. Why is that? Well, it turns out that the brain itself lacks pain receptors. Just imagine, during brain surgery, doctors can wake you up at any moment because the brain cannot feel the pain of the operation. This raises the curiosity, why would such an important organ lose the ability to sense pain? Does it hide some kind of wisdom of life?

Next, let's discuss cell renewal. Most cells in the human body undergo metabolism and renewal over time, but brain cells are an exception. From the moment of birth, brain cells hardly ever renew. This means that our brain cells accompany us throughout our lives, witnessing our growth and aging. What kind of life mystery lies behind this phenomenon?


Lastly, let's explore a more profound question: who is controlling whom? We often feel like we are the masters of our brains, but upon closer examination, can we really fully control our brains? When we have nightmares, who creates those terrifying dreamscapes? And who prevents us from waking up from them? Perhaps, we don't fully understand our own brains, and sometimes, we might even become puppets of our brains.

This journey of deep reflection about the brain has led us to reconsider this organ filled with mystery. It is not only the source of our thoughts but also the cradle of our emotions. It serves as both the window through which we perceive the world and the engine that drives us to explore the unknown. However, can we truly control it completely? Perhaps, this will always remain a question that we can never deeply ponder.
