I was referring, rather clumsily, to the maximum firing rate of a neuron. I still believe that much of the important stuff is encoded in the firing rate. It is interesting that firing rate in the eye can be interpreted by the brain as color. Sort of like a heterodyne.

I didn't think you literally meant there was a clock (if there were, everyone's head would probably hum softly), but what you posted got me thinking how impressive it is that there isn't one. Building an unclocked logical device of any complexity is tough; any gate with two inputs and independent circuit paths of different lengths goes undefined until everything arrives. Neurons have lots of inputs, and the number of different paths must be enormous.
