I am seeking references to work showing that the frequency of firing of
neurons drifts. This is known to occur, for example, in cardiac rhythms:
the variation in heart rate can be decomposed into zero-mean fluctuations
plus a fixed drift, so the frequency can be written as Fo +/- D*t + N(t),
where Fo is the mean frequency, D is a fixed value for the drift, t is
time, and N(t) is a zero-mean noise contribution. I am looking for other
examples of the same behavior, preferably in neurons.
