This is a question that has interested many people for a long time
now, and provoked a lot of argument. In fact, the recently published
work by Zach Mainen and Terry Sejnowski (in Science, I think; I don't
have the exact reference) was an attempt to measure this underlying
variability experimentally, for cortical pyramidal cells. Their
references will provide a few pointers to the existing literature.
