Complete Firing-Rate Response of Neurons with Complex Intrinsic Dynamics
Fig 4
The qualitative shape of voltage response depends on QL.
Here we classify the current-to-voltage filter shapes shown as colored solid lines in (a), (b), and (c), which show the three QL-regimes with respective examples for QL = 0.1, 0.75, 10. In each plot, the high pass component of the voltage response is shown as the colored dashed lines, one for each of three representative values of its characteristic frequency, ωLτw = 102 > γ(blue), ωLτw = 1(green), and ωLτw = 10−2 < γ−1(red). The solid black line is the low pass component of the voltage response. For the regime shown in (a), the green case can not be achieved when w is hyperpolarizing (g > 0) and the example red case cannot be achieved because it violates the stability condition QL < ωLτw.
