033 The Receptive Field of a Ganglion Cell
In this episode, I talk about receptive field of ganglion cells, showing how rods and cones are connected to bipolar cells that are then connected to Ganglion cells. The more bipolar cells you have connected to Ganglion cells, the larger...

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...

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

037 How Sound is Transferred to the Inner Ear
In this video, I show how Sound is accurately transferred to the inner ear. Since there is fluid inside the cochlea, impedance matching needs to take place. It happens due to the 1.3 to 1 ratio of movement between the maleus, incus and...

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...

040 The Role of Hair Cells in Hearing
In this video, I show the details of how the bending of the stereocilia on the inner hair cells results in the release of neurotransmitters, which ultimately results in hearing. Enjoy.

065 The Anatomy and Functions of the Frontal Lobe
In this video, I go into more detail on the anatomy of the frontal lobe, and the functions of the various regions in the frontal lobe. I define gyri and sulci, and even show a video of someone with Broca's aphasia, which shows how damage...
