Excitable Plants
In researching last month's Origins essay on the origin of the nervous system, I was struck by the range of behavior and electrical excitability exhibited by organisms that lack nerve or muscle cells. Some sponges, for example, have a sneeze-like reflex that flushes out sediment (see a video), whereas others generate electrical "action potentials" much like the impulses that convey information in nerves and brains. Electrical signals have been recorded even in the single-celled Paramecium, where they appear to play a role in escape and avoidance behaviors.
