Is intelligence confined to the
brain only or to all cells
of our body?
This is a hard one! How do you define intelligence?
Intelligent people have skills, and would need other
cells than their grey ones to employ those skills. In
order to be a good mathematician, intelligence is
important. Without social interaction, the most
genious thoughts are wasted: we have to express them.
But to be a good dancer, or a good musician, you name
it, you need a proper dosis of intelligence also.
There must be a perfect coordination between brain and
body, feelings and expression of feelings, thoughts
and deeds, so the complete body is needed.
Now the question is, is that because intelligence is
not confined to the brain, or is it that, with smart
brain cells AND a good body chemistry, we can achieve
more with our intelligence? A paralyzed person can be
highly intelligent. So I think the brain is the key
factor. What you DO with your intelligent talents is
What about the biochemistry. Suppose intelligence
would be the number of brain cells, or the complexity
of cellular interaction within the brain (I am not
aware that the biochemical nature of intelligence has
been identified so these are just examples). In order
to work correctly, the brain needs sufficient supply
of oxygen, to name a thing. I don't think such basic
requirements are worse than perfect. In other words,
each brain is probably supplied with the best of
things, unless there is a disease to prevent this.
The key factor to your question is how to define
intelligence. And that is not an easy thing.
