Optical Mapping of Cardiomyocytes in Monolayer Derived from Induced Pluripotent Stem Cells
Cells, 2023 Optical mapping is a powerful imaging technique widely adopted to measure membrane potential changes and intracellular Ca2+ variations in excitable tissues using voltage-sensitive dyes and Ca2+ indicators, respectively.

On the accuracy of cell-attached current-clamp recordings from cortical neurons
Frontiers in Molecular Neuroscience, 2022 Cell-attached current-clamp (CA/CC) recordings have been proposed to measure resting membrane potential and synaptic/agonist responses in neurons without disrupting the cell membrane, thus avoiding the intracellular dialysis that occurs in conventional ...

The microbiologist’s guide to membrane potential dynamics [PDF]
, 2020 All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

Mitochondrial membrane potential [PDF]
Analytical Biochemistry, 2018 The mitochondrial membrane potential (ΔΨm) generated by proton pumps (Complexes I, III and IV) is an essential component in the process of energy storage during oxidative phosphorylation. Together with the proton gradient (ΔpH), ΔΨm forms the transmembrane potential of hydrogen ions which is harnessed to make ATP.

Membrane potential and cancer progression [PDF]
Frontiers in Physiology, 2013 Membrane potential (Vm ), the voltage across the plasma membrane, arises because of the presence of different ion channels/transporters with specific ion selectivity and permeability. Vm is a key biophysical signal in non-excitable cells, modulating important cellular activities, such as proliferation and differentiation.

Event-Based Update of Synapses in Voltage-Based Learning Rules
Frontiers in Neuroinformatics, 2021 Due to the point-like nature of neuronal spiking, efficient neural network simulators often employ event-based simulation schemes for synapses. Yet many types of synaptic plasticity rely on the membrane potential of the postsynaptic cell as a third ...
