Sentence examples for membrane potential oscillations from inspiring English sources
Increased numbers of Na+ channels in demyelinated axons may produce an increase in axonal membrane potential oscillations [ 88], thereby potentiating neurotoxic levels of intra-axonal Ca2+, culminating in axonal degeneration [ 89].
Hb9+ interneurons exhibit strong postinhibitory rebound and demonstrate pronounced membrane potential oscillations in response to chemical stimuli that induce locomotor activity.
Free parameters in the model were fitted to produce membrane potential oscillations matching those seen during swimming.
Nonlinear ionic currents, mediated by voltage-gated ion channels, play a key role in generating membrane potential oscillations and action potentials.
LA projection neurons generate stable subthreshold membrane potential oscillations at around 2.4 Hz [30], which are implicated in shaping network activity related to fear and anxiety [31].
The interaction of gabaergic and non-NMDA glutamatergic systems spared by ketamine and xylazine generates slow membrane potential oscillations that drive cortical neurons periodically [30].
A relaxation oscillator is a model of a cellular pacemaker, commonly used to describe the slow envelope of membrane potential oscillation in bursting neurons (for example [18]).
Recordings of the membrane potential of CA1 neurons in behaving animals show that although spikes precess against the LFP, they always occur around the peak of a cell's intrinsic membrane potential oscillation (MPO) (Harvey et al., 2009).
This indicated that phase shifts of the membrane potential oscillation retained information about past inhibitory synaptic events for durations that were much longer than the duration of the events themselves measured as voltage shifts.
Indeed, hybrid models which incorporate recurrent connectivity and oscillatory dynamics have recently been proposed [107 109], and potentially provide a more complete account of the experimental data, explaining both the ramp depolarisation and membrane potential oscillation seen within the firing field [105,106,109].
In the absence of efferent stimulation, we found 75 cells that displayed electrical resonance that could be observed either as damped oscillations in response to depolarizing current steps (blue trace in Fig. 3A) or as increases in membrane-potential oscillation at particular frequencies in response to frequency sweeps (data not shown).
