The story of the egg spans millions of years, from the first vertebrates that dared to venture onto land to today’s mammals, including the platypus, and of course birds. Like chickens? We’re here to tell you: The egg came first.

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.

You Can "Catch" Alzheimer's Disease

In this video Paul Andersen gives an overview of the human urinary system. The system consist of the kidneys, ureters, bladder, and urethra. The kidneys excrete waste from the blood in urine. He explains how the nephron is responsible...

Our brains aren't exactly like a computer's hard drive, but it can still be fun to think about just how much storage space we have in our noggins.

Alzheimer's doesn't have to be your brain's destiny, says neuroscientist and author of "Still Alice," Lisa Genova. She shares the latest science investigating the disease -- and some promising research on what each of us can do to build...

Most people will take a pill, receive an injection, or otherwise take some kind of medicine during their lives. But most of us don't know anything about how these substances actually work. How can various compounds impact the way we...

When talking about the brain, neurons have been dazzling scientists for a long time. But behind every successful neuron is a glial cell - particularly one type of them: microglia.

Imagine a future where nobody dies— instead, our minds are uploaded to a digital world. There they could live on in a realistic, simulated environment with avatar bodies, calling in and contributing to the biological world....

Hank explains the gift that your brain gives you every day: the gift of neural plasticity -- the ways in which your brain actually changes at the cellular level as you learn.

Sometimes we learn the coolest stuff by being wrong! This week, we learned we were wrong about birds always laying eggs and mice being addicted to cocaine!

Mental health is incredibly complex, due in no small part to the complicated interactions of chemicals and neuroreceptors in our brains. Here are four common misconceptions about antidepressants, and what the science behind them actually...

Next stop in our tour of your sensory systems? VISION. With a little help from an optical illusion, we take a look inside your eyes to try to figure out how your sense of vision works -- and how it can be...

Biology and technology grew closer together when scientists manufactured neurons that acted like those in a brain! And birds evolved to protect themselves in two ways: fight and flight.

Being a teenager is hard. Especially when hormones play their part in wreaking havoc on the teenage body and brain. In this episode, Hank explains what is happening to the during the angsty-time. ----------

Settle in for a smörgåsbord of brain facts.

Discover the power of neuroplasticity and how you can rewire your brain for mental strength and resilience. This video explains the science behind neuroplasticity and provides practical strategies for harnessing its potential to enhance...

Memories are stored as microscopic changes at the connections between neurons in the brain. When a person wants to remember something, they have to retrieve the information from the part of the brain where it is stored. The retrieval...

Glial cells are various types of brain cells. There are 3 main types of glial cells - astrocytes, oligodendrocytes, and microglial cells. These cells protect neurons, help neurons pass information, and keep the brain healthy. These group...

In this video, Justin from the Institute of Human Anatomy takes you on a fascinating journey through the world of neural oscillations and their profound influence on meditative states. Starting from the very basics, we explore the...

In this video we cover what the nervous system is, how it relies on nerve cells and synapses, and what a reflex arc is.
