Anatomically speaking, there is nothing in the head except a bunch of interconnected nerve cells, just like the electronic USB hubs in our bodies. However, the intertwined gray and white matter, which weighs only 1.4 kilograms, controls our state of consciousness, enabling us to think, feel, and experience the care, fear, and longing of the human world. At the same time, it monitors our somatic body, from blood pressure to hormone regulation. We can have a happy and fulfilling life, obviously because of the brain. The brain is a never-ending machine that never shuts down, even when we sleep. Shutting down means death. Fast imaging technology is how we can see how the brain moves in real time. As the pulses and amplitudes of light pass through the surface and deep structures of brain tissue, the mirror image that unfolds before our eyes is as brilliant as the Aurora Borealis. Each mental activity can exhibit a unique light show. Images of the brain’s activity are a tool for scientists to further explore the brain. Whether it is a veteran suffering from cranial trauma or a patient suffering from a mental disorder, there are a series of behavioral and somatic function changes due to damage to specific areas of the brain. However, more of the mystery comes from the surgeon’s surgery. Modern neurosurgeons are able to perform real-time explorations on a conscious patient, holding a baton like probe that touches different structures of the cerebral cortex, where language, knowledge or sensation can be stimulated or stopped in real time. Some are obsessed with reductionist methodology as a way to understand this holy grail in the organ and wonder if it might be a threat to our human nature. At the same time, there is an effort to demystify some of the questions that have long plagued us: How does the spirit move? Whatever interest you have in your head, how does it arise? And how do you practice it? What impact do your interests have on your life? We are obsessed with this.
