On: Averaging is a convenient fiction of neuroscience

It is a low-pass filter in the frequency domain with a roll-off that is not smooth. I quite like [1] as a quick reference.

Not the OP but we're talking about different things here. Much of the concern about averaging is about averaging across trials. Smoothing a spike train over time isn't really the issue that this thread is concerned with, since that's just averaging successive samples within some small window.
