Sentence examples for spike initiation threshold from inspiring English sources

When current drove the membrane potential to the spike initiation threshold, v ¯, a spike time was recorded and a 1-ms absolute refractory period was initiated.

The analysis of the refractory properties yielded results consistent with the case of current injection, with changes in the membrane time constant, equilibrium potential and spike initiation threshold.

Another approach to recreate the SAI afferent's irregular interspike intervals could be to introduce probabilistic firing and adaptive thresholds at spike initiation zones, similar to that done for vibratory stimuli (Jahangiri and Gerling, 2011; Dong et al., 2013).

An input of size γ c is sufficient to push the voltage across the threshold for single spike initiation.

It is likely that the slow depolarization evoked by a long pulse leads to a partial inactivation of Na+ channels and activation of KA channels prior to spike initiation, and therefore, increases the firing threshold and delay.

Third, a neural dynamics module, consisting of an array of leaky integrate-and-fire (LIF) models that represent spike initiation zones, summed receptor currents and, at threshold, produced spike times.

Arbor configurations differed in number of spike initiation zones (3 5) and initial end-organ sizes (13 20).

When the spikes were induced by threshold currents [1], the time of spike initiation (TSI, which is defined as a point of the suddenly rise in dV/dt, i.e., threshold) at the axon was ahead of that at the soma (Fig. 2A).

Here, (tau_{m}=5mbox{ ms}) is the membrane time constant, (varDelta_{T}= 3mbox{ mV}) gives the slope of the spike initiation, and (V_{S}= -53mbox{ mV}) is the "soft" threshold for spike initiation.

Spike initiation in a quiescent neuron is often associated with a threshold phenomenon, which happens when a critical transmembrane potential is exceeded.

We hope the revised text is clear in explaining that addition of an inward or outward HH conductance active at voltages near threshold changes how the fast and slow currents interact during the spike initiation process.
