ACTO 1 (IMAGE) Rice University Caption These snapshots of actin filaments, motors and linkers show how a branched network changes during an avalanche as tension in the system, indicated by color, is released over 10 seconds. The blue squares at top left highlight concentrated high-tension regions that become low-tension areas (top right) after the event. Researchers suspect avalanches in the actomyosin networks in neuronal cells are one possible mechanism by which the brain preserves memories.
