Figure 9. 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 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 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 Fig. 2.
