In this lesson on the brain's neural networks, students investigate the structure and function of the neuron. They discover ways in which engineers apply this knowledge to the development of devices that can activate neurons. Includes...

Messages within the brain and the rest of the nervous system are sent very rapidly. These messages are conducted by cells called neurons. Neurons are specialized to receive and transmit message and neurons are connected in networks. In...

This module focuses on the science that explains the effects that drugs have on the brain and, by extension, a person's thoughts, feelings, and behaviors. Specifically, it focuses on the adolescent brain. Adolescents may be more...

Students learn to identify the type of cells that make up nervous tissue.

York University provides a good site on the physiology of nerve transmission. Embedded vocabulary help is available if you need it.

Read a passage about using darkness to cure Amblyopia (Lazy Eye) and answer the follow-up questions.

Nervous system signals are transmitted electrically along individual neurons, but neurons are separated from each other by a tiny gap. Chemical messengers called neurotransmitters cross the gap between neurons. Neurotransmitters fit into...

Nervous system messages are sent as electrical signals along the length of axons and dissolved salts are important for electrical signaling in cells. In this lesson students are introduced to this concept by creating an electrical...

An adult human can distinguish up to 10,000 odors. You use your nose to figure out what to eat, what to buy and even when it's time to take a shower. But how do the molecules in the air get translated into smells in your brain? This...

A resource for information on illnesses of the motor neuron.

A good description of the process of transmission across the synapse in nerve cells.

Learn about Charles Sherrington, the Nobel Prize winner in Physiology or Medicine for his work on the functions of neurons.

Prepare for the MCAT by reading this passage and answering questions based on the given table about how different viral doses affect behavioral or electrical abnormalities in mice.

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most...
