- Nice post. As a neurologist, I also enjoy thinking about these
- questions. I think you are right that consciousness may be an
- "afterthought" at times, but it may also initiate brain events. The
- different parts of the brain are all interlinked but not strictly
- subservient to one another. There is usually significant activity in
- many different parts at once. The ascending reticular activating
- system, under control mainly of the prefrontal cortex via the thalamus,
- appears to enable one area of the cortex at a time, allowing us to
- select which activity to attend to. Thus, a thought can develop in one
- area of the brain before we are conscious of it (when the neural
- activity has progressed along sufficiently, it requests the attention of
- the prefrontal cortex). On the other hand, the development of a thought
- can take place in the area already enabled by the ARAS, as might occur
- when we are trying to solve a problem on a test.

- Actually, science has nothing at all say about the soul, since it is
- by definition supernatural.
