How our Personality is Wired


Today’s wake up word is Myelin: It is a fatty insulator that surrounds the axon of some kinds of nerve cells allowing signals to pass through preferentially over those channels. When we learn motor skills like an instrument, our body responds by mylenating certain channels to make that happen easier over time. This is why we become competent at tasks. Myelin is essential for the proper functioning of the nervous system. Myelin is the reason habits form (including what we call our identity and character in many respects) and why patterns of behavior are harder to break once established whether in an individual or a culture, and why these rituals may serve us or imprison us depending on how they are wired and how that wiring serves to help us navigate the variables of our environment.
