A Simple and Low-Cost, but Naturalistic Method for Introducing Students to Action Potentials
Current trends in science education recommend the complementary use of virtual and hands-on methods of teaching. In neurobiology, for instance, there is a plethora of virtual laboratories and simulators that can be readily combined with traditional ...

It is well known that cardiac electromechanical delay (EMD) can cause dyssynchronous heart failure (DHF), a prominent cardiovascular disease (CVD). This work computationally assesses the conductance variation of every ion channel on the cardiac cell to ...

Resilience of compound action potential peaks to high‐frequency firing in the mouse optic nerve
Action potential conduction in axons triggers trans‐membrane ion movements, where Na+ enters and K+ leaves axons, leading to disruptions in resting trans‐membrane ion gradients that must be restored for optimal axon conduction, an energy dependent ...

Differences in Intersubject Early Readiness Potentials Between Voluntary and Instructed Actions
Readiness potential (RP) is a slow negative electroencephalogram (EEG) potential prior to voluntary action and was first described by Kornhuber and Deecke (1965).

Cardiac cells depend on specific sarcolemmal ion transporters to assure the correct intracellular pH regulation. The sodium/bicarbonate cotransporter (NBC) is one of the major alkalinizing mechanisms.

On mathematical modeling of the propagation of a wave ensemble within an individual axon
The long history of studying the propagation of an action potential has revealed that an electrical signal is accompanied by mechanical and thermal effects. All these effects together generate an ensemble of waves. The consistent models of such a complex

ALTERNATIVE TO Q WAVE DIAGNOSIS USING CARDIAC ACTION POTENTIAL PROPAGATION TIME MEASUREMENT
The diagnosis of myocardial infarction is done by ECG through the observation of Q waves in one or more leads. The paper describes the relationship between Q waves and the propagation time of the Cardiac Action potential and a technique by which this ...

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
