a: amyloid plaques ~
b: a traffic jam
What:
"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."
