For some clarity. Scientists study the brain through behavior and imaging. They watch to see which part of the brain lights up when certain behavior takes place. Now if the brain is damaged and one cannot walk, then one can be taught to walk again which means a different undamaged part of the brain is used.
The brain has been studied for many, many years and no one has found any memory, emotions, or other data therein. They never will because it is not the brain that controls the body. I have spent many hours studying human anomalies. I believe more is to be learned from anomalies than from normal events when it comes to us humans.
The videos on savants testify to this. Badly handicapped people with amazing skills.
Now there is a group of people that have little or no brain and they do amazing things also.
We are spirit first and human second, and there is a ton of evidence to show this in our literature.
