  Neurophysiology of pipe flow
  Dwight Barkley
  I will discuss a surprising analogy between the subcritical transition to turbulence and the dynamics action potentials in neurons. Laminar flow plays the role of the rest state of a neuron, while turbulent flow plays the role of the excited state. From a simple model motivated by electrophysiology, I will show that it is possible to explain many large-scale patterns observed in transitional pipe flow.
