Diffusion & Electrostatics

To completely understand resting potential, we need to take a look two basic phenomena in nature: diffusion and electrostatics.  Diffusion is the process by which particles spread out or mix, for instance, in a solution. Take for example a beaker of water. Imagine that you drop a bit of dye into the beaker and wait. After the initial ‘splash’ of the dye falling into the … Continue reading Diffusion & Electrostatics

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
