Deniz,
Pay no attention to brain.
Keep thinking about your "spontaneous activation", and like Alex said, it won't be spontaneous, and therefore, not what you're looking for.
Brain,
If you're going to reply to a topic, keep it on subject. Don't bring up something totally different.
Deniz,
If you have many questions, great! Write the ones you truly want to find the answer to down, on paper. Then photoread. Then you can postview, to find the parts that might contain your answer. Wait a while, then begin to activate, and dip into those spots where your answers are.
If you don't have any questions, preview the book, skim it. Get trigger words. Formulate questions off of those.
