Document Summary
The mind-brain problem (also called mind-body problem) deals with how and why brain activity. A fundamental property is a property that something has. We cannot be explain why it has that property. For example, matter has the fundamental property, mass. We cannot explain why it has mass; it just does. We can say that consciousness, like mass, is a fundamental property. Mass is present in all atoms (of the body). However, consciousness only occurs in certain parts of certain kinds of nervous systems. Also, there is no consciousness when one is in dreamless sleep or coma. We evolved these mechanisms because ancient animals these mechanisms survived and reproduced better than animals with other organisms. In the nervous system (brain included), there are two kinds of cells: neurons and glia: neurons vary widely in their size, shape, and functions. They convey messages to one another and to muscles and glands: glial cells are smaller than neurons and have many functions.
