THE NEURON (Slides 4 to 14) • Based on the PowerPoint attached
... A neuron is resting when its membrane forms a partial barrier between the inside and outside of the neuron. The solution contains electrically charged particles called ions. When the neuron is at rest, there are more negative ions on the outside which is called the resting potential. A resting neuro ...
