The ionic current flowing through a protein channel in the membrane of a biological cell depends on the concentration of the permeant ion, as well as on many other variables. As the concentration increases, the rate of arrival of bath ions to the channel's entrance increases, and typically so does the net current. This concentration dependence is part of traditional diffusion and rate models th...

Learning and logic are fundamental brain functions that make the individual to adapt to the environment, and such functions are established in human brain by modulating ionic fluxes in synapses. Nanoscale ionic/electronic devices with inherent synaptic functions are considered to be essential building blocks for artificial neural networks. Here, Multi-terminal IZO-based artificial synaptic tran...

The resting and action potentials of the m. gastrocnemii of normal and dystrophic mice have been measured in vitro, under various conditions of the ionic environment. The observed effects are consistent with the view that, when equilibrium is established between internal and external ionic concentrations, the resting potential is determined very largely, and perhaps entirely, by the gradient of...
