Exactly 10.002 milliseconds. No, just kidding. It varies widely from
neuron to neuron, and in different regions of the same neuron, and over
time, etc, etc. It can be anywhere from under a millisecond to tens of
milliseconds. This is a pretty complicated subject, actually.  But 10
milliseconds wouldn't be bad for a really gross approximation.
