Serial correlation coefficient at lag 1 as a function of the time scale separation.

<p><b>A</b> Serial correlation coefficient in the case of channels (corresponding to ) for stochastic adaptation (circles, Eq. (3)) and 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>B</b> shows the corresponding plot for channels (corresponding to ) and . The gray-shaded region marks the relevant range for spike-frequency adaptation. was varied by changing at fixed (), all other parameters as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1001026#pcbi-1001026-g002" target="_blank">Fig. 2</a>.
