Q: Why would we need a lay-level model of how the nervous system works?
A: We already have lay-level models on how some of the body’s systems work — and they help us relate and adjust what we’re familiar with about the system, to the terms of its good functioning — to keep it in balance.
For example, when we are familiar with the kinds of foods that make up a balanced diet, we can keep them in our diet, to balanced nutrition. In the nervous system, when we know how the subtle patterns of muscle tension we call “feelings” are formed and released to form a reversal of tension we experience as emotional balance, we can do what it takes to support this balance
