Cardiac late Na⁺ current: proarrhythmic effects, roles in long QT syndromes, and pathological relationship to CaMKII and oxidative stress.

Belardinelli L1, Giles WR2, Rajamani S3, Karagueuzian HS4, Shryock JC5.
Heart rhythm : the official journal of the Heart Rhythm Society.Heart Rhythm.2015 Feb;12(2):440-8. doi: 10.1016/j.hrthm.2014.11.009. Epub 2014 Nov 11.
Myocyte sodium channel current that persists throughout the plateau of the cardiac action potential is referred to as late sodium current (I(Na-L)). The magnitude of I(Na-L) is normally small, but can increase significantly in common acute and chronic pathological settings as a result of inherited a

A classification of spiking neurons according to the transition from quiescence to periodic firing of action potentials is commonly used. Nonbursting neurons are classified into two types, type I and type II excitability. We use simple phenomenological spiking neuron models to derive a criterion for

Sodium-activated potassium conductance participates in the depolarizing afterpotential following a single action potential in rat hippocampal CA1 pyramidal cells.

Liu X1, Stan Leung L.
Brain research.Brain Res.2004 Oct 15;1023(2):185-92.
The depolarizing afterpotential (DAP) following an action potential increases the excitability of a neuron. Mechanisms related to the DAP following an antidromic or current-induced spike were studied in CA1 pyramidal cells by whole-cell recordings in hippocampal slices in vitro. In DAP-holding volta
