I , the gray matter, which is found in me?

What is gray matter? This is a question that I still have not found the true answer. Who determines the amount of gray matter in the body? Is it possible to increase it and how? What can it give a person? What if from the higher mind separates us is the amount of gray matter?

For all of the dowry, God created us in his own image.  Accordingly, the higher mind is the most gray matter there and in my subjective opinion it there is enough to be considered higher.

You have - the gray matter.
