This site, created by a biology professor at Eastern Kentucky University, provides an overview of the brain and nerve senses of the bird.

Students study the adult brain, and learn the connections between the cerebrum and brain stem through the diencephalon, and from those regions into the spinal cord.

Describes the organization and function of the nervous system.

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...

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...

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 activity students are introduced to this concept by creating an electrical...

Loads of answers to just about any question you may have about comas. This site discusses what coma is, whether there is treatment, what the prognosis might be like, research on comas, and more.

Find out about the major sections of the neurological exam and the connection between location and function in the nervous system. Also learn the benefit of a rapid assessment for neurological function in a clinical setting.

Students learn the pathways that sensory systems follow into the central nervous system, and understand the difference between the two major ascending pathways in the spinal cord.

This report is entitled "The Structure of the Brain." Scroll down to section 3.2.3 for more on brain anatomy.

Brain cells called neurons send information and instructions throughout the brain and body. The information is sent via electro-chemical signals known as action potentials that travel down the length of the neuron. These neurons are then...

This website from the University of Washington is divided into three sections: "History of Cocaine," "Effects of Cocaine on the Nervous System," and "The Brain on Cocaine." Read interesting facts about the use of cocaine before it became...

At this site learn about the dangers and effects associated with tobacco use and nicotine. Read about how nicotine effects the body and brain and how a nicotine addiction is very difficult to break.

Summarizing research found at the Mayo Clinic, this article explains why kids, who have only smoked a few cigarettes, "experience the same symptoms of nicotine addiction as adults who smoke heavily." Learn about how nicotine affects the...

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...
