NEURONS, BRAIN CHEMISTRY, AND NEUROTRANSMISSION

Human body systems students play a card game, "Locks & Keys" in order to learn that neurotransmitters carry a message from one neuron to another by fitting into a receptor site on the receiving nerve cell. While this activity can...

Have you heard that humans only use about 10 percent of their brains? Well, don't believe it! After describing the tremendous amount of energy needed to power our 86 billion densely packed neurons, the narrator also explains how our...

A good description of how the neurotransmitters are involved in cell communication. Very good site.

Injection, taking a pill, or inhaling are the three main ways to administer a drug. But how do these drugs affect the brain? Watch a video that explains how neurons use neurotransmitters to communicate to one another in the brain.

The human brain is complex. Messages within the brain and the rest of the nervous system are conducted by cells called neurons. Drugs and other substances can interfere with or modify the transmission of messages between neurons. In this...

When one thinks of neurotransmitters, zombies do not usually come to mind. In this lesson plan, learners take on the roles of neurons and must transmit messages. This will help them to appreciate the importance of properly functioning...

PBS site explores mirror neurons and why humans get so worked up watching other people. Contains links to a video segment on the discovery and significance of mirror neurons, a research update involving a study using pro dancers, an...

Zap! Ouch! That hurts! But why? And how come people don't experience or respond to pain in the same way? Take a journey on the sensing pathway, from your nociceptors, along your nerves, up your spinal cord, to neurons and glial, through...

We all know that the brain is responsible for our thoughts, actions, memories, and emotions, but it's far busier than we can possibly imagine. Watch this short video as it explores how life as we know it is made possible...

Is your brain running a little slow? Just reboot it and you'll be good to go. This advice may sound ridiculous, but by watching this video you will learn how through a process called neurogenesis, adult brains are able repair and replace...
