This is Neuron in the thalamus: Oscilloscope tracing of the activity from neurons in the thalamus (nucleus parafascicularis). 
In the recording, you should be able to see several action potentials with different sizes. There is one large spike and several smaller ones.<BR>

And this is a simulation of Channel Gating during an action potential from the Gary G. Matthews: ''NEUROBIOLOGY  Molecules, Cells and Systems''<BR>
