The Neuroscience for Kids "Page of the Month" for August is the Pfizer Company's "Brain: The World Inside Your Head" at:
This web site is a companion to the new brain exhibit that opened last month at the Smithsonian Institution in Washington, D.C. The Pfizer company is funding the exhibit and has developed the web site to assist visitors. You will find three options when you enter the site: "Exhibit Tour," "Brain Games," and "Grown-ups." The Exhibit Tour is a virtual guide to the museum exhibits. When you click on one of six exhibits, you will be sent to a page describing the exhibit. "Brain Games" takes you to a quiz, a brain puzzle and a downloadable game (which was not ready when I visited the site). The "Grown-ups" link provides adults with suggestions on how to talk to kids about neurological disorders. The site is also adding a teacher's guide to help students when they visit the exhibit. Finally, if you are 18 years old or older, you can order free brochures and pamphlets about a variety of health problems.
The museum exhibits will be visiting the following cities:

If you can't make it to one of these places to see the real museum
exhibit, the web site will show you what you are missing.
Last month as I was reading the table of contents from the journal "Toxicon," an article with the words "newt" and "tetrodotoxin" caught my eye. As you may know, newts are amphibians. What you may not know, is that some newts, according to the article, contain a neurotoxin called tetrodotoxin (TTX). TTX affects nerve cells by blocking sodium channels and thereby preventing the transmission of electrical signals. The immediate danger of this is that nerves to muscles that control breathing stop working. TTX is found in several animals, including the pufferfish. In Japan, some people eat the pufferfish, but it must be prepared by an expert or it can be fatal! Small doses of TTX may cause headaches, tingling in the face and hands, and stomach pain. Higher doses may reduce blood pressure and breathing or cause paralysis and death.
With a little library detective work, I discovered descriptions of three people who ate toxic newts. In two cases, men swallowed Oregon rough-skinned newts on dares. Soon after eating the newts, these men became weak, vomited and felt tingling in their lips or hands. One man died and the other recovered 24 hours later. The third case involved a two-year-old girl who bit off the tail of the family pet: an Oregon rough-skinned newt! The girl started to cry immediately after biting the newt's tail and the girl's mother was able to brush the tail out of the girl's mouth. Both the girl and the newt survived.
It is likely that TTX is used by newts and other animals as a form of protection. A bite of one of these animals is sure to persuade a predator to look elsewhere for food. I suspect the little girl never took a second bite of her family pet.

Part medical mystery, part political drama and part crime story, "The Case of the Frozen Addicts" chronicles 10 years in the life of neurologist J. William Langston as he unravels the cause of a disorder that has frozen a handful of heroin addicts. The story begins in 1982 when six heroin addicts inject themselves with a bad batch of synthetic heroin. A few days later, these people find themselves unable to move. Although their ability to think, see and feel are unaffected, they cannot move their muscles. These people are frozen, with symptoms similar to those of Parkinson's disease.
Sadly, "The Case of the Frozen Addicts" is a true story. Langston describes his journey to discover why these people are unable to move. Along the way he encounters a chemical that holds the potential to revolutionize the study of Parkinson's disease. The road he takes is not smooth: competition from other laboratories, professional jealousy and research problems all impede his progress. Nevertheless, Langston's discoveries start new research to investigate the causes and potential treatments for Parkinson's disease and send Langston down a new career path.
Authors Langston and Jon Palfreman make the 309 pages of
"The Case of the Frozen Addicts" turn quickly. The book has just enough
technical information to provide readers who do not have a neuroscience
background with an understanding of the science. I highly recommend "The
Case of the Frozen Addicts" to anyone looking for a well-written mystery
with a neuroscientific twist.
