Noradrenaline Modulates the Membrane Potential and Holding Current of Medial Prefrontal Cortex Pyramidal Neurons via β1-Adrenergic Receptors and HCN Channels

open access: yesFrontiers in Cellular Neuroscience, 2017
The medial prefrontal cortex (mPFC) receives dense noradrenergic projections from the locus coeruleus. Adrenergic innervation of mPFC pyramidal neurons plays an essential role in both physiology (control of memory formation, attention, working memory ...

Modulation of the ISFET response by an immunological reaction [PDF]

open access: yes, 1989
A new method is presented for the detection of an immunological reaction in a membrane. Antigens (or antibodies) are taken up in a porous membrane, which covers the gate area of an ISFET. By stepwise changing of the electrolyte concentration, a transient

Electrically induced bacterial membrane-potential dynamics correspond to cellular proliferation capacity

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Transmembrane voltage in bacteria plays a central role both in electrical signaling and cell proliferation. However, whether proliferation state influences the response to electrical signals was unknown.

The membrane potential of human platelets [PDF]

open access: yesBlood, 1983
Abstract The membrane potential of the human platelet was investigated using the membrane potential probes 3,3′-dipropyl-2,2′-thiadicarbocyanine iodide and tritiated triphenylmethylphosphonium bromide. The membrane potential in physiologic buffer was estimated to be 52–60 mV inside negative.

Ion channels to inactivate neurons in Drosophila

open access: yesFrontiers in Molecular Neuroscience, 2009
Ion channels are the determinants of excitability; therefore, manipulation of their levels and properties provides an opportunity for the investigator to modulate neuronal and circuit function.

A Novel Calcium-Activated Potassium Channel Controls Membrane Potential and Intracellular pH in Trypanosoma cruzi

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Trypanosoma cruzi develops in environments where nutrient availability, osmolarity, ionic concentrations, and pH undergo significant changes. The ability to adapt and respond to such conditions determines the survival and successful transmission of T ...

Modulatory Effects of Acidic pH and Membrane Potential on the Adsorption of pH-Sensitive Peptides to Anionic Lipid Membrane

open access: yesMembranes, 2021
Anionic lipid membrane electrostatic potential and solution pH can influence cationic peptide adsorption to these bilayers, especially those containing simultaneously acid and basic residues.

Emerging Roles of the Membrane Potential: Action Beyond the Action Potential

open access: yesFrontiers in Physiology, 2018
Whilst the phenomenon of an electrical resting membrane potential (RMP) is a central tenet of biology, it is nearly always discussed as a phenomenon that facilitates the propagation of action potentials in excitable tissue, muscle, and nerve. However, as

A low-voltage activated, transient calcium current is responsible for the time-dependent depolarizing inward rectification of rat neocortical neurons in vitro [PDF]

open access: yes, 1987
Intracellular recordings were obtained from rat neocortical neurons in vitro. The current-voltage-relationship of the neuronal membrane was investigated using current- and single-electrode-voltage-clamp techniques.

Electrophysiology, Unplugged: Imaging Membrane Potential with Fluorescent Indicators.

open access: yesAccounts of Chemical Research, 2019
Membrane potential is a fundamental biophysical property maintained by every cell on earth. In specialized cells like neurons, rapid changes in membrane potential drive the release of chemical neurotransmitters.
