How Neurons Communicate: The Synapse

In this video I explain how two neurons communicate using a neurotransmitter that travels across the synapse to receptor sites. This neurotransmitter can then influence the flow of ions in the postsynaptic neuron which can change its likelihood of firing an action potential.

The Action Potential

In this video I explain how an action potential is triggered in a neuron when it reaches its threshold. I explain the movement of ions, resting potential, and the all or none principle of neural firing. I also cover how the message is propagated along the axon and how myelin makes this process more efficient. Don’t forget to subscribe to … Read More
