"The release of norepinephrine is like super glue for memories; it helps lock memories into place."
"Bringing these neurotransmitter functions together using a metaphor of driving a car, norepinephrine is like putting your foot on the gas, acetylcholine is steering the car, and dopamine is the wish to go for a nice drive."
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.
