I am not a specialist and I do not dispute what you say here. Indeed I
find attractive the idea that information is encoded in the exact
timing of the spikes. Is there any information yet on what 'reads' the
time intervals between spikes and 'decodes' them to give back the
original information to the receiving neuron (or neurons)? At the least
a 'stopwatch' would be needed, would it not?
