014 The Journey Down the Axon
How does the signal that starts at the axon hillock travel down the axon, and why does it only go in one direction?

016 The Release of Neurotransmitter
When the action potential reaches the axon terminal, this triggers a series of events that result in the release of neurotransmitter to the synaptic cleft. Neurotransmitters bind to the receptors on the postsynaptic membrane causing a...

019 What is Summation (2 Types)
In this video, I discuss the topic of summation. It covers both temporal and spatial summation, dealing with how it can result in the addition of PSPs to result in an action potential. Enjoy!

020 Facilitation
In this episode, I talk about the concept of facilitation and explain how it results in a stronger signal in the postsynaptic cell.

007 What is an action Potential
In this episode, I answer a question that is fundamental to our understanding of the nervous system. That question is - What is an action potential/nerve impulse. Action potentials are the signals that are sent throughout the nervous...

008 The All-or-None Action Potential
In this episode, I talk about the all-or-none nature of the action potential. Action potentials/nerve impulses either happen or they don't. If the stimulus is strong enough to cause the membrane potential to reach threshold, this will...

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...

010 Repolarization: Phase 2 of the Action Potential
The second phase of the Action Potential is Repolarization. Voltage-gated Potassium channels open and Potassium leaves the cell making the membrane potential more negative.

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...
