Static vs. dynamic aspects of brain structure

There is a book called “On Intelligence” by Jeff Hawkins, and it is about yet another theory of the human brain’s operation. The author pointed out several gaps in current researches in neurology and AI.

However, the book dealt with static aspects of the brain’s structure. It omitted the dynamics. In particular, the following points were not covered:

  1. Factors affecting formation, destruction and strength of synapses connecting two neurons to each other (see also: Hebbian learning).
  2. Growth of axons and dendrites - where do they prefer to grow?
  3. Initial wiring in a fetus’ brain.
  4. Existence and effect of any chemical means for non-local communication between neurons.
  5. How are new neurons created and how do they integrate into the existing network?

The only dynamic aspect of brain operation, which was dealt with by the book, was the firing pattern of neurons.
