A stochastic mechanism for signal propagation in the brain: Force of rapid random fluctuations in membrane potentials of individual neurons.
Hong D, et al. J Theor Biol 2016. PMID 26555846
There are two functionally important factors in signal propagation in a brain structural network: the very first synaptic delay-a time delay about 1ms-from the moment when signals originate to the moment when observation on the signal propagation can begin; and rapid random fluctuations in membrane potentials of every individual neuron in the network at a timescale of microseconds. We provide a stochastic analysis of signal propagation in a general setting. The analysis shows that the two factors together result in a stochastic mechanism for the signal propagation as described below. ...

Motoneuron membrane potentials follow a time inhomogeneous jump diffusion process.
Jahn P, et al. J Comput Neurosci 2011. PMID 21479618 Free PMC article.
Especially the Ornstein-Uhlenbeck process is popular to describe the stochastic fluctuations in the membrane potential of a neuron, but also other models like the square-root model or models with a non-linear drift are sometimes applied. ...Moreover, the spiking characteristics are well described by a Poisson spike train with an intensity depending exponentially on the membrane potential....

Axonal model for temperature stimulation
Fribance S, et al. J Comput Neurosci 2016. PMID 27342462 Free PMC article.
The new model predicts that a rapid increase in local temperature produces a rapid increase in membrane capacitance, which causes an inward membrane current across the membrane capacitor strong enough to depolarize the membrane and generate an action potential. ...Our study indicates that the axonal membrane capacitance-temperature relationship plays a critical role in inducing the transient membrane depolarization by a rapidly increasing temperature, while the effects of temperature on ion channel kinetics cannot induce depolarization. ...

Membrane potentials in Rana temporaria muscle fibres in strongly hypertonic solutions.
Fraser JA, et al. J Muscle Res Cell Motil 2006. PMID 17051346
Conventional microelectrode methods were used to measure variations in resting membrane potentials, E(m), of intact amphibian skeletal muscle fibres over a wide range of increased extracellular tonicities produced by inclusion of varying extracellular concentrations of sucrose. ...Thus: (1) halving or doubling [K(+)](e) produced negative or positive shifts in E(m), respectively in isotonic or moderately hypertonic (<2.7tau), but not strongly hypertonic (>3tau) solutions; (2) subsequent restoration of isotonic extracellular conditions produced further positive changes in E(m) consistent with a dilution of the depleted [K(+)](i) by fibres regaining their original resting volumes; (3) quantitative modelling similarly predicted a gradual net efflux of K(+) as the balance between active and passive [K(+)] fluxes altered due to increased transmembrane [K(+)] gradients in hypertonic and low [K(+)](e) solutions. ...

Effect of the use of a model with peer instruction for the teaching of membrane potential and action potential.
Albuquerque FDS, et al. Adv Physiol Educ 2018. PMID 30387701 Free article.
A group of teachers from Northeast Brazil developed a model of membrane potentials and action potential and tested the hypothesis that using the peer-instruction model would provide a better performance for students in reading traditional texts and lectures. ...At the end of the lecture, everyone responded to a posttest. Student performance in the pretest did not differ significantly between groups. ...

Membrane potentials recorded from the mucosa of the toad's tongue during chemical stimulation.
Eyzaguirre C, et al. J Physiol 1972. PMID 5016359 Free PMC article.
The potentials evoked by the salt solutions often overshot the zero membrane potential level by several millivolts. The positive-going potential change produced by application of salts was increased during hyperpolarization of the membrane by inward current and was decreased by current of the opposite sign. Application of salts during depolarization of the membrane to a certain positive level produced a negative-going potential change. ...

Membrane resistance and shunting inhibition: where biophysics meets state-dependent human neurophysiology.
Paulus W and Rothwell JC. J Physiol 2016 - Review. PMID 26940751 Free PMC article.
Activation of neurons not only changes their membrane potential and firing rate but as a secondary action reduces membrane resistance. ...Membrane conductance is also increased during shunting inhibition, which accompanies the classic GABAA IPSP. This short-circuits nearby EPSPs and is suggested here to contribute to the magnitude and time course of short-interval intracortical inhibition and intracortical facilitation....

Ionic basis of membrane potentials of epithelial cells in rat small intestine.
Barry RJ and Eggenton J. J Physiol 1972. PMID 4646579 Free PMC article.
Sodium and potassium diffusion potentials largely determine both the mucosal and serosal membrane potentials. For the mucosal membrane, P(K):P(Na) is 1.26:1, and is probably higher for the serosal membrane. Chloride makes no significant contribution to membrane potentials.8. Potentials generated by the electrogenic sodium pump are superimposed on diffusion potentials across the serosal membrane....
