Role of connectivity and fluctuations in the nucleation of calcium waves in cardiac cells

Hernadez-Hernandez, Gonzalo; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (2015-11-20)
Article
Accés obert

Spontaneous calcium release (SCR) occurs when ion channel fluctuations lead to the nucleation of calcium waves in cardiac cells. This phenomenon is important since it has been implicated as a cause of various cardiac a ...

We demonstrate that proper levels of additive white noisy currents generate such pulses spontaneously. In other words, we fully reproduce the experimental dynamics when we use the appropriate basic neuron model, the ...

Stochastic coupled map model of subcellular calcium cycling in cardiac cells

Romero Castañeda, Luis; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (Institute of Physics (IOP), 2019-02-01)
Article
Accés obert

In this study, we analyze a nonlinear map model of intracellular calcium (Ca) and voltage in cardiac cells. In this model, Ca release from the sarcoplasmic reticulum (SR) occurs at spatially distributed dyadic junctions ...

Cultured neurons in vitro quickly connect to one another to establish a spontaneously active network within a week. The resulting neuronal network is char- acterized by a combination of excitatory ...

The timing statistics of spontaneous calcium release in cardiac myocytes

Asfaw, Mesfin; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (2013-05-17)
Article
Accés obert

A variety of cardiac arrhythmias are initiated by a focal excitation that disrupts the regular beating of the heart. In some cases it is known that these excitations are due to calcium (Ca) release from the sarcoplasmic ...
