Kv3.3 subunits control presynaptic action potential waveform and neurotransmitter release at a central excitatory synapse

open access: yeseLife, 2022
Kv3 potassium currents mediate rapid repolarisation of action potentials (APs), supporting fast spikes and high repetition rates. Of the four Kv3 gene family members, Kv3.1 and Kv3.3 are highly expressed in the auditory brainstem and we exploited this to

Bridging the Molecular-Cellular Gap in Understanding Ion Channel Clustering

open access: yesFrontiers in Pharmacology, 2020
The clustering of many voltage-dependent ion channel molecules at unique neuronal membrane sites such as axon initial segments, nodes of Ranvier, or the post-synaptic density, is an active process mediated by the interaction of ion channels with scaffold

Excitation and contraction of cardiac muscle and coronary arteries of brain‐dead pigs

open access: yesFASEB BioAdvances, 2023
Excitability and contraction of cardiac muscle from brain‐dead donors critically influence the success of heart transplantation. Membrane physiology, Ca2+‐handling, and force production of cardiac muscle and the contractile properties of coronary ...

Sodium Channels Involved in the Initiation of Action Potentials in Invertebrate and Mammalian Neurons

open access: yesBiophysica, 2022
Living organisms react to external stimuli to adapt their activity to the environment for survival. Acquired information is encoded by neurons by action potentials (APs) in a series of discrete electrical events.

Upper Limit on the Thermodynamic Information Content of an Action Potential

open access: yesFrontiers in Computational Neuroscience, 2020
In computational neuroscience, spiking neurons are often analyzed as computing devices that register bits of information, with each action potential carrying at most one bit of Shannon entropy.

Action-space clustering of tidal streams to infer the Galactic potential [PDF]

open access: yes, 2014
We present a new method for constraining the Milky Way halo gravitational potential by simultaneously fitting multiple tidal streams. This method requires full three-dimensional positions and velocities for all stars to be fit, but does not require ...

The effect of myocardial action potential duration on cardiac pumping efficacy: a computational study

open access: yesBioMedical Engineering OnLine, 2018
Background and aims Although studies on the relation between arrhythmias and the action potential duration (APD) have been carried out, most of them are based only on electrophysiological factors of the heart and lack experiments that consider cardiac ...
