In his book The Third Ear, author Chris Lonsdale makes the following claim in chapter 14:
Some years ago, scientists did a very interesting experiment. They placed a single, live, heart cell into a Petri dish in a lab. This lonely little cell was beating for a while, then, slowly, the strength of the beat declined, getting slower and weaker, until it finally stopped. Dead.
I know very little about biology and anatomy, but the idea that a single, isolated heart cell, with no attached nervous system, can beat, strikes me as dubious. Is there any truth to this claim?
