amyloid plaques


a: amyloid plaques ~
b: a traffic jam


"To send messages to their neighbours (and on to the rest of the body), neurons use chemical transmitters that cross the gaps between cells. Here, amyloid plaques are like a traffic jam, blocking cell signalling. Connections between cells are lost - first in the hippocampus, the region in the brain for memory and learning. Neurons die and the affected brain tissue shrinks."

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.
