Equilibrium & Potentials

Let us consider a basic schematic membrane, with one side of it being the intracellular side and the other side being the extracellular one. We use a voltmeter, which has a ground electrode that we place outside of the cell and the other end of the electrode that we place inside of the cell, to measure the difference in voltage between the intracellular and extracellular … Continue reading Equilibrium & Potentials

Resting Potential & Voltage

Although there are many different kinds of neurons in the nervous system, the same basic electrical principles underlie their function. Before we can get into the complexities of neuronal signaling, let us take a look at the electrical principles that are in play when the cell is at rest.  When you look at a typical neuron, you can see that it has a variety of … Continue reading Resting Potential & Voltage
