Abstract

For a model neuron, there is typically a critical value I c with the property that for I < I c , there is a stable equilibrium with a low membrane potential, whereas periodic firing is the only stable behavior for I > I c , as long as I is not too high.

Notes

  1. 1.

    For very high I, there is usually a stable equilibrium again, but at a high membrane potential. This is referred to as depolarization block, an observed phenomenon in real neurons driven very hard [9], but we don’t discuss it here; see also exercises 10.6, 12.3, and 12.4.
