Im wondering that if we are the brain why we cant control things like pain and our immune system.
In: Biology
The brain is only part of the system that controls the body. The body is like a whole colony of co-dependant organs that keep each other alive and work together for some mutual functions. Ours brains don’t have access to all of those functions, likely because they don’t need to. In some cases the best the brain can do is foster conditions for the result it wants to occur.
You could think of it like a farmer, if the farm was an extension of themselves. The farmer can till land, plant seeds and water them- but despite all their power and authority over the environment actually commanding the seeds is something they can’t do. They don’t have access or tools to make that happen.
In a similar fashion you can go work out, feed your body and sleep well but can’t spontaneously grow muscles by mental power alone.
In a similar way, we can’t turn our immune system or pain systems on or off, they’re outside of our control. My best guess as to “why” is that if a baby was born with that interconnectivity they’d accidentally cause themselves a lot of damage, or even die.
