Hmmm. What can a person who is brain dead do?
Are you really meaning the contriubtions of genetics vs environment? If so, that is much different from brain functions.
Is it possible that everything a person is or does is a function of the brain? Or are there other factors that influence who you are?
I'm not sure that everything a person is is a function of the brain. I think factors like how and where you were raised effect who you are. I'm not sure how else to answer this and I have to write an essay based on these questions.

The brain is the executive organ for the body. Except for a few reflexive responses (e.g., knee jerk) very little goes on that does not involve the brain. Reading your question, analyzing it, and responding by typing this answer all require a multitude of activities within the brain. I believe that every thought that I have has correlated neuronal activity within my brain. We are just beginning to understand the complexity of the brain.
However, the brain itself is effected by various factors, including such things as past experiences, diet, oxygen level, medications, trauma and so on. For example, learned responses require changes in the neurons and their connections within the brain.
I searched Google under the key words "brain functions" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps a little more. Thanks for asking.
