Table 3 Exact adaptive behaviour of classes of circuits considered in the text to different stimuli
From: Adaptive information processing of network modules to dynamic and spatial stimuli
Feedback | Incoherent Feedforward | Inflow-outflow | Other | |
|---|---|---|---|---|
Ramp | No (unless zeroth order reaction present*) | Yes (no saturation of feedforward legs), also threshold/saturation model | Yes, provided signal doesnt act on output. Further restrictions if there are multiple outflow variables | Yes |
Periodic stimulus (mean value) | No (unless zeroth order reaction present*) | No | Yes if only one outflow. Restrictions on signal location for multiple outflow variables | Yes |
Static gradient (mean value) | No (unless zeroth order reaction is present, not studied) | No (but see hybrid case in Table 2) | Yes for one outflow variable, for some species diffusible; further restrictions on signal location for two outflow variables | No |
Spatio temporal periodic stimuli | No (not discused) | No | Travelling wave but not standing wave | Both Travelling and standing wave (almost exact: see text for details) |
