"It is well-known that calcium is another positive molecule useful for the conduction of a nerve impulse to a muscle fiber. However, Clay Armstrong, a neurobiologist, believes that calcium may play a larger role. Armstrong suspects that calcium is in charge of the gated channels that release potassium and sodium to facilitate a nerve impulse. Armstrong's theory proposes that calcium ions are like a door to these gated channels. Calcium must move to release the ions and calcium must return before the impulse will stop and homeostasis is returned "
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.
