Actually, the mechanisms are chemical processes involving trophic factors (i.e. inputs to those processes) and alteration of the physical structures the signals are transmitted with. You say "the brain grows" but the alteration of its structure to strengthen our weaken transmission and connections in response to signals is how it grows usefully. Which was present in the work described by the article.
- mjburgess 6y agoAn infant brain and an adult brain do not differ by their "strength of connection and trasmission". It is a hypothesis, and I think a false one, that this is identical to learning. The dynamical number and arrangement of neuronal tissues is not incidental. The micro (sub-neurone), medial (neurone) and macro structure (morphology) of the brain is time-varying, not merely its connection patterns (conditioned on fixed micro/medial/macro).
