Figure 1
Linear analysis of the neuron models.
Linear analysis of the model neurons with fixed external conductances. A: Resting potential as a function of the background inhibition-to-excitation ratio k for the canonical value of 
(solid lines), and as a function of the background synaptic excitation 
for the canonical value of 
(dashed lines). Solid lines refer to the bottom axis; dashed lines to the top axis. Circles show the canonical values of the corresponding parameters. B: Effective membrane time constant as a function of k and 
. Line styles, colors and symbols as in A. C: Effective intrinsic frequency as a function of k and 
. Line styles, colors and symbols as in A. D: IPSPs in response to a single presynaptic pulse delivered at time t = 0, in the presence (dashed lines) or absence (solid lines) of fixed background conductances. Inset shows the membrane potential response to an instantaneous perturbation.
