The Synapse

In this video Paul Andersen explains how the synapse allows information to travel from one axon to the next. He starts by differentiating between electrical and chemical synapses. He then details the action of the chemical synapse whereby an incoming action potential triggers the opening of voltage-gate Ca2+ channels that trigger the release of neurotransmitters from vesicles into the synaptic cleft. These neurotransmitters dock with receptors and can send either excitatory or inhibitory messages onward. He also explains how long term potentiation can lead to memory formation.

I personally just want to take the time to thank Paul Anderson for all the time and energy he has put into this. Educating the minds of people across the world, and might I add, for free. All these diagrams, illustrations and presentations in general would take a fair bit of work. Thank you Paul and thanks to your team helping you as-well if there is one.

I really appreciate this mans dedication to education, you can see in his eyes how hard he must work. Poor man, hopefully he gets some rest. And some recognition for this work

This dude literally helped me ace AP bio back in high school without even touching the textbook, and do well on the ap test. Now I get help again in Anatomy and physiology in University.
