  1. A brilliant piece of machinary. Pity we use such a small component of it. It also goes to show how much more we can actually use and hence accomplish.

  2. Interesting facts. I’d like to get the book for a read. It will be fabulous to be able to tell the brain what to think and when to think it as opposed to the other way around.

  3. I did not the above facts & now knowing the above does not enlighten me much more . The size of the numbers seems to suggest that we might have great capacity .

  4. This sounds like it is quoted straight from my textbooks and my last year final exams! 🙂

    A great reminder of how fascinating a tool our necktops really are!
