Let's talk. Why are we talking only about the causes hidden in the brain? If the activity of the heart stops and the blood flow to the brain stops, then the person ceases to generate hypotheses and other thoughts and feelings. Let's continue. If we are talking about the causes that are concealed only in the brain. Then, in the first place, the generation of new ideas and discoveries is connected with the neural networks of the frontal lobes of the brain. Of course, we must take into account the connections of the frontal lobes with other parts of the brain. Neural networks of frontal lobes of the brain are a kind of "key" link, which makes an effective assessment of convergence and divergence processes in the brain. It is to these departments of the brain that it is responsible for making the "last" decision.
