009 Depolarization: Phase 1 of the Action Potential
In this video, I talk about the first phase of the action potential - Depolarization. In order for the action potential to take place, the stimulus needs to be strong enough to bring the membrane potential at the axon Hillock to...

How Do Neurons Work?
Neurons send signals through a mechanism called action potential. Action potentials are electrical signals that pass through the neuron’s axon. This causes the neuron to pass the signal to the next neuron. Action potentials are the...

Events of the Neuron Action Potential
The graded potentials in the cell body and dendrites have summed to yield an action potential at the axon hillock. Here, we discuss the events of the action potential as its traverses along the axon.
