Synaptic NMDA receptor activity at resting membrane potentials. [PDF]
Front Cell Neurosci, 2022 NMDA receptors (NMDARs) are crucial for glutamatergic synaptic signaling in the mammalian central nervous system. When activated by glutamate and glycine/D-serine, the NMDAR ion channel can open, but current flux is further regulated by voltage-dependent

Effects of membrane potentials on the electroporation of giant unilamellar vesicles. [PDF]
PLoS One, 2023 Living organisms maintain a resting membrane potential, which plays an important role in various biophysical and biological processes. In the context of medical applications, irreversible electroporation (IRE) is a non-thermal and minimally invasive ...

Fluctuation spectra of free and supported membrane pairs [PDF]
European Physical Journal E 23, 103-116 (2007), 2006 Fluctuation spectra of fluid compound membrane systems are calculated. The systems addressed contain two (or more) almost parallel membranes that are connected by harmonic tethers or by a continuous, harmonic confining potential. Additionally, such a compound system can be attached to a supporting substrate.

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 ...

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.
