Neither the physical brain nor the mental brain have more of an influence than the other. First of all, the physical brain can limit people in certain ways and they can't change that. In "The Brain" Clive had a physical disease that limits his ability to remember things that happen, but he can remember how to speak and move his body. On the other hand, the mental brain has to be in the right mindset to do what is wanted to be done. If someone goes into school thinking that they are already smart enough, a fixed mindset, then they will not succeed. That person has to go into school with a growth mindset. They need to embrace failure and learn from it, then they will succeed. Similarly, a player's mindset during a basketball game has to be in the right place and their physical brain has to be prepared as well. The player has to believe that he can win. He also has to be able to go from being really pumped up while playing, to being very calm while taking a free throw; just like in "The Brain". Together, the physical brain has to be prepared for an event and the mental brain has to be in the right mindset. Only then, people are able to complete the task at hand.
In my life experiences, I have found that the physical and mental brain both have an influence. I believe that my mental mindset has an effect on my performance. When I play a hockey game, I have to tell myself that I can do it, "I can score this goal" or "I can keep up with this guy". Similarly, my mind has to be physically prepared for the game as well as mentally. I have to be pumped up for my hockey game to succeed. If I just came out of the locker room without preparing myself in any way, I wouldn't do well. To get myself ready for a hockey game, I warm up by jogging around the arena and doing a small, easy workout. Then I listen to some rock music, which gets me in the zone. After doing all of that, I am physically and mentally ready for my game. I do this when I am getting ready for a test in school too. To get my physical brain prepared for a test, I study all night. To get mentally prepared, I have to believe that I can do well. Both the physical and mental brain effect how I perform in sports and school, I have to get pumped up or study and believe in myself to succeed.
