Actin pulls upon and stabilizes soluble cytoplasmic polyadenylation element binding proteins into longer, insoluble prion-like fibers, a process believed to be key to stabilizing long-term memories. Rice University researchers simulated the force (F) applied by actin through computer models that predict how proteins are likely to find their least-energetic (and most stable) states.

Thank the little “muscles” in your neurons for allowing you to remember where you live, what your friends and family look like and a lot more. New research at Rice University suggests actin filaments that control the shape of neuron cells may also be the key to the molecular machinery that forms and stores long-term memories...
