WebIt is observed that the spike threshold gets depolarized and the rate of membrane depolarization (dV/dt) preceding AP is reduced as adaptation currents reduce firing rate. It is indicated that the presence of inhibitory adaptation currents enables the neuron to generate a dynamic threshold inversely correlated with preceding dV/dt on slower ... WebFor measurement of spike threshold in response to injected current steps, each neurone was depolarized to a baseline voltage of approximately –70 mV using positive holding current, and current steps (usually 1.6, 3, 6, 12, …
