Sentence examples for adaptation current from inspiring English sources

We did not have to make any assumption about the frequency dependence of the adaptation current.

The last is reasonable because the adaptation current responds to spike activity, and any baseline current could be absorbed into the other currents.

We circumvented this difficulty by applying the mean value theorem to the adaptation current, rather than approximating the firing rate itself.

We showed that the adaptation current is nearly proportional to the applied current when the adaptation conductance is large (Claim 1).

It was argued in [9] that linearization does not need to be imported into the system by assuming that the adaptation current was linear, as in [6].

In addition to a SNIC, the analysis in [9] used the approximation that the adaptation current is proportional to the firing rate, as did [6] and [8].

An alternative approach is to focus on adaptation currents that provide negative feedback to slow the firing rate.

The two approaches were married by theoretical analysis of HH-type models with various adaptation currents appended [6 9].

We further show how to analyze neural field models with linear adaptation currents, and determine the conditions for the dynamic instability of spots that can give rise to breathers and traveling waves.

For adaptation currents with more complex voltage dependence, such as a slowly inactivating (mathrm {Na}^) current with fast gating variables, our theory may not apply even in the presence of a SNIC because the scaling argument used to derive Eq. (20) may not be valid even approximately.

Although it could be possible to propose an ad hoc form for the spike, it would certainly be more interesting to extend the results here to models where neurons activity depends on additional variables such as adaptation currents, as in the FitzHugh-Nagumo model [39 42], or activation-inactivation variables as in the Hodgkin-Huxley model [35].
