Hank and PhD candidate Casey Massena go deep into the chemistry of a molecule that Casey helped create! Then Jessi joins the show to show off Ecuador, one of her many conures!

Neurons often get all the credit for running the brain, but the work done by Ben Barres at Stanford University proved that glial cells are far more crucial to brain functioning than we had previously realized.

Scientists have been turning to the animal world for inspiration for a long time, including for medicines. And many different types of animals have been responsible for this inspiration, including sharks, spiders, and... roadkill.

The human brain is complex and awe-inspiring, so of course we have been trying to figure out how to control it. From electricity to light, here are some of the ways we have attempted to command our wrinkly thinkers.

Optogenetics may allow us to use light like a remote control for our brains, and treat diseases like retinitis pigmentosa.

Explore cell signaling with the Amoeba Sisters! This introductory video describes vocabulary such as ligand and receptor. It includes the stages of cell signaling (reception, transduction, and response) and different types of signaling...

Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action...

A Quick Question answer that explains the chemistry that makes minty things taste “cool” and spicy things taste “hot”.

Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body.

Paul Andersen explains the structure, function and importance of adenosine triphosphate (ATP). He begins by describing the specific structure of the molecule and its three main parts: adenine, ribose sugar, and phosphate groups. He...

Ready for action? Time to get your neurons firing with some action potential. If you thought resting potential was tough to understand, it seems like action potential is that much more difficult. However, thanks to Alie Astrocyte, we...

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...

A lot of techniques and methods used in neuroscience have been developed thanks to modern technology and science. But what did neuroscientists do back in the day before all this fancy stuff? Well, turns out the giant squid axon was...

Part 1 of 2 of excitation-contraction coupling | In this video, we discuss excitation-contraction coupling from events on the motor neuron axon all the way through opening of calcium channels in the sarcoplasmic reticulum (SR).

In this video, we discuss all steps of excitation-contraction coupling in skeletal muscle from events on the motor neuron axon all the way through cross-bridge cycling between actin and myosin.

In this video, we will discuss the events of Excitation-Contraction Coupling from the motor neuron action potential to release of Ca2+ from the sarcoplasmic reticulum (SR). **Part 2 Coming Soon

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!

The nugget explains the uptake, absorption and transport of mineral nutrients in plants.

Have you ever wondered what commotio cordis is or what causes it? In this video, we dissect the physiological mechanism of commotio cordis.

We've learned about the types of muscle, including skeletal muscle, and we know then when these muscles contract, we are able to move our bodies around. But how exactly does this happen on the molecular level? There is an astonishing...
