neuroplasticity
"Neuroplasticity is like how bones work. As you use a bone there are organisms inside the bone (marrow) and they are constantly weakening and strengthening the bones in the places needed. For a runner it could be in the outside of the left femur, while the right femur may become weaker, sincer the runner is running around an oval track in a reverse-clockwork motion. This example is not scientifically ccurate but i hope it helps to serve to show you how bones work. The neurons and glial cells in the brain are similiar."
It is not easy to first try to carve a path with your toboggan. To glide easily down a slope, a path must be forced into being by repeated attempts to slide down the hill or by tamping down the snow with feet and shovels. Waxing and waning with time, the white noise of the storm is the background against which your mark is made; if the path is not maintained, it will get covered again. Once created though, attempts to slide down beside your path in some different way will be easily deferred to the original lane unless you purposefully create a more definite fork in your course.

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
