Web4 Mar 2015 · If you have a series inductance and a shunt capacitance with very little resistance, you have a resonant circuit. If you stimulate the resonant circuit with a fast positive or negative edge, it will resonate, which includes overshoot and undershoot. Traces can act as series inductors, and digital inputs typically have some capacitance. WebAn action potential is a rapid change in membrane potential that is governed by the opening and closing of ion channels in the plasma membrane of the neuron. In this tutorial, we will review the phases of an action potential measured from a small area of a neuron's membrane. ...

Web28 Sep 2014 · Taste receptors, hearing and balance, light touch, pain and temperature also send information to the brain. Action potentials in the heart originate in specialized cardiac muscle cells called autorhythmic cells. These cells are self-excitable, able to generate an action potential without external stimulation by nerve cells. Web5 Jul 2012 · The period from the initiation of the action potential to immediately after the peak is referred to as the absolute refractory period (ARP) (see Figs. 1 and 2). This is the time during which another stimulus given to the neuron (no matter how strong) will not lead to a second action potential. Thus, because Na + channels are inactivated during ...
