The Pharmacology Education Partnership (PEP) is an online interactive resource for high school teachers with tools to teach biology and chemistry. Students learn basic biology and chemistry concepts through topics about cocaine, nicotine, and steroids. The program was produced by a partnership between Duke University Medical Center and the North Carolina School for Science & Math, and was funded with a Science Education Award from the National Institute on Drug Abuse.When you visit the PEP web site for the first time, you need to fill out a short survey and enter a username and password. Once you finish registering, choose "Teacher," "Student" or "Other" to gain access to the materials. Click on one of the six books (labeled 1-6) in the upper middle part of the screen to navigate through the different modules. Each module has notes for teachers, class activities and a short quiz. The modules can also be downloaded in PDF format. __________________________________________________________
A bit of discomfort in the dental chair was better than a broken tooth, so I had the tooth fixed. With modern anesthetics to dull the pain, my experience was not too bad.
Trips to the dentist have not always been so pain-free. Italian anthropologists have recently found teeth that were drilled thousands of years ago before the invention of anesthetics. The researchers discovered 11 drilled molar teeth from nine adults in an ancient graveyard in Pakistan. The teeth are estimated to be 7,500 to 9,000 years old!
The old teeth were drilled to depths of 0.5 to 3.5 mm and each hole was 1.3 to 3.2 mm in diameter. The teeth showed evidence of smoothing that indicated that the drilling was done on living people who continued to use their teeth to chew after they were drilled.
It is highly likely that the unfortunate people who had their teeth drilled thousands of years ago experienced tremendous pain. Nerve fibers inside of the dental pulp are extremely sensitive to heat, touch and chemicals. Anesthetics, such as Novocain, reduce dental pain by blocking the conduction of action potentials into the central nervous system. Although the ancient dentists may have used a variety of drills, I am glad that my dentist has added anesthetics to his bag of dental tricks.

The library I use at the University of Washington has many books with impressive titles such as "Principles of Neural Science" and "The Central Nervous System of Vertebrates." These massive textbooks discuss the anatomy and physiology of the brains of different animals in exquisite detail. To someone just beginning to study the nervous system, however, these books are not very useful. It was with great surprise that I discovered a neuroanatomy book at my local public library that young students would enjoy: "You Can't Use Your Brain If You're a Jellyfish" by Dr. Fred Ehrlich.
Dr. Ehlich's book is the only comparative neuroanatomy book for young readers that I have ever seen. He starts the book by discussing which animal has the "best" brain. Ehlich correctly points out that each animal has the proper brain for the things that it does. The brains and abilities of invertebrates (worms, mosquitoes, cockroaches) and vertebrates (birds, cats, dogs, monkeys, apes, humans) are then compared and contrasted.
Poems at the end of each chapter and the many colorful, cartoon
illustrations by Amanda Haley reinforce the ideas that Dr. Ehrlich
presents. Although the book is not detailed enough to be used for
research, it is an excellent introduction to the field of neuroanatomy.
B. "Inside the Autistic Mind" is the cover story of Time magazine (May 15, 2006. This magazine also has an article about the potential effects of melatonin on sleep.
C. "The Mystery of Dreams" is the cover story of U.S. News and World Report (May 15, 2006).
D. "When Colleges Go On Suicide Watch" by Julie Rawe and Kathleen Kingbury (Time magazine, May 22, 2006) discusses what schools are (and are not) doing for students with mental illness.
E. "Good Vibrations" by Avery Comarow (US News and World Report, May 22, 2006) discusses the high quality of new, small hearing aids.
F. "Health: Can You Really Botox the Blues Away?" discusses using the neurotoxin Botox for depression and "The Little One Said" discusses co-sleeping. Both articles appear in the May 29, 2006, issue of Newsweek magazine.
G. "Toward Better Pain Control" by Allan I. Basbaum and David Julius (Scientific American, June, 2006) discusses advances in pain research and possible new treatments for pain problems.
H. "Dazzling & Dangerous - Venomous Creatures" is a new museum exhibit
that opened on May 26, 2006, at the Aquarium of the Pacific in Long Beach,
California. The exhibit showcases beautiful, but dangerous animals that
use venom for survival. Many of these animals, such as the rattlesnake,
blue-ringed octopus, poison dart frog and Gila monster, use toxins that
attack the nervous system. For details about the exhibit, see:
