a: An astrocyte ~
b: nursing cell

What: "There are two important support cells to know about -- oligodendrocytes and astrocytes. An oligodendrocyte puts myelin around your nerve connections. (In MS, myelin is disrupted.) Myelin is like insulation. An astrocyte is a nursing cell. It sits next to the dopamine neuron and feeds it. The astrocyte is like a hospital."

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.
