How Noisy Adaptation of Neurons Shapes Interspike Interval Histograms and Correlations

Serial correlation coefficient at lag 1 as a function of the time scale separation.
A Serial correlation coefficient in the case of
channels (corresponding to

for deterministic adaptation (squares, Eq. (2)). Theoretical curves for stochastic adaptation, Eq. (72), and deterministic adaptation, Eq. (9), are displayed by a dashed line and a solid line, respectively. The zero baseline is indicated by a dotted line. B shows the corresponding plot for
channels (corresponding to
) and
