The human brain was so smart, so why was it so difficult to fully develop it?
Although the human brain is very smart, it is difficult to fully develop it because the human brain is divided into two halves, each with different functions. The left hemisphere was mainly responsible for language, logic, reasoning, and other abstract thinking abilities, while the right hemisphere was mainly responsible for space, music, images, and other concrete thinking abilities. The nerve fiber bundles between the two halves also had different branches. Some branches were connected to different brain regions, while others were connected to different sensory systems, allowing human thoughts to be used to different degrees in different fields. In addition, the human brain is also affected by physiological and environmental factors such as age, stress, nutrition, exercise, and other factors that may affect the degree of brain function development. Therefore, although the human brain was very smart, it took a lot of effort and time to fully develop it.
