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 ... WebLow-threshold spikes (LTS) refer to membrane depolarizations by the T-type calcium channel. LTS occur at low, negative, membrane depolarizations. They often follow a membrane hyperpolarization, which can be the result of decreased excitability or increased inhibition. LTS result in the neuron reaching the threshold for an action potential.

WebMay 6, 2024 · The spike threshold recorded in cortical neurons in vivo depends on the rate of depolarization and the nature of the stimulus (7, 11). For example, in the barrel cortex, the spike threshold is hyperpolarized for the preferred stimulus and depolarized for the nonpreferred stimulus .
