How Hearing Works - Journey of Sound to the Brain
How do we hear? How does sound get transferred from the ear all the way to the brain? In this video, I go into all the juicy details. Listen up and have fun.

011 Hyperpolarization - the end of the action potential
After Depolarization and Repolarization comes Hyperpolarization, where the membrane potential falls beneath the Resting Membrane Potential. Watch the video to learn more!

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...

018 Agonists and Antagonists
In this video, I talk about what agonists and antagonists are and how they affect the neuron on the level of the neurotransmitter. 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.

031 How Rods and Cones respond to Light
In this episode, I go through the process of how rods and cones respond to light. I use Rods as an example and show how Rhodopsin, Transducin and Phosphodiesterase are involved in the process. Enjoy

038 How We Hear Different Pitches
In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different...

039 The Function of the Organ of Corti
In this video, I talk about the organ of corti, which is found on top of the basiliar membrane inside the cochlea. When the basilar membrane vibrates up and down, that causes the organ of Corti to move up and down, and the tectorial...

The Action Potential in All Its Glory - A Review/Summary
What does it take for an action potential to take place? What are depolarization, repolarization, and hyperpolarization? How are voltage-gated ion channels involved? In this video, you will get answers to all these questions.

Photosynthesis - Energy in a Cell
Photosynthesis is the process that plants use to convert energy from the Sun into food. In this lecture, I talk about the process of photosynthesis, and show the steps involved in producing glucose. I go into the Light dependent and...

The Plasma Membrane - A view of the cell
The plasma membrane is responsible for maintaining a balance. In this section, I talk about both the structure and the function of the plasma membrane. I deal with the components of the plasma membrane and their functions.

004 Ion Channels: Proteins in the Membrane of Neurons
In this video, I go through the details of the 4 types of proteins in the membrane of neurons: The passive/leakage ion channels, Sodium Potassium pump, Voltage-gated ion channels and ligand-gated ion channels

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.

Glycerol-Phosphate Shuttle | NADH, Electron Transport Chain and ATP Yield
Lesson on the Glycerol Phosphate (aka Glycerol-3-Phosphate) Shuttle. NADH produced from glycolysis is unable to enter into the mitochondria because the mitochondrial inner membrane is impermeable and highly selective. Therefore, the cell...

Human Water Cycle - Drinking Water
Water. It's an essential building block of life, constantly moving in a hydrologic cycle that flows in a continuous loop above, across and even below the Earth's surface. But water is also constantly moving through another cycle -- the...

What are viruses
In this video we are going to look at what viruses are. Viruses are a type of microorganism. They are too small to be seen with the naked eye: much smaller than bacteria, and about 100 times smaller than human cells. They come in many...
