Ion fluxes during the action potential inChara

Ion fluxes during the action potential in Chara.

The Different Mechanisms of Action Potential Propagation in the Heart

It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...

Ion escape fluxes from Mars

[1] A 3D, multi-species, non-ideal MHD numerical code was used to calculate the ion escape fluxes from Mars. The calculations were carried out for six cases with different nominal solar wind, solar cycle and crustal field orientation conditions and the total escape fluxes (the sum of the three major ionospheric species, O, O2 , and CO2 ) varied by about an order of magnitude from 2.7 10 to 2.4 ...
