The Neuroscience for Kids "Page of the Month" for September is the Multimedia Neuroscience Education Project (MNEP) at:
The MNEP was designed by the Neuroscience Program at Williams College (Williamstown, MA) with funds from the National Science Foundation. The web site takes you on a tour of the four steps of synaptic transmission: 1) synthesis and storage of neurotransmitters; 2) neurotransmitter release; 3) neurotransmitter binding to postsynaptic receptors and 4) neurotransmitter inactivation.
Each step is described briefly and illustrated with several animations.
You must have the "RealPlayer" plug-in (free download) for your browser to
run the animations. When I used the web site, most of the animations did
not come up immediately. Rather, I had to click on a text link to run
them. Those of you with a slow Internet connection will have to be
patient because the large image files take a long time to load. Each
animation is approximately 30 seconds in length and includes very nice
graphics. These animations are a great way to learn how signals
are sent through the nervous system.
When people fly across multiple time zones, they often feel tired and worn out for several days after their flight. This is called "jet lag" and is caused by changes in body rhythms such as those involved with body temperature and sleep.
To examine how jet lag affects the performance of professional athletes, researchers in the Department of Neurology at the University of Massachusetts Medical School examined the win-loss records of 19 East Coast and West Coast baseball teams in the 1991-1993 seasons. Overall, teams won 54% of their games on their home fields. However, home teams won 62.9% of their games if their opponents traveled west to east the day before they played. If a team traveled east to west the day before a game, the home team won only 56.2% of the time. These data show that home teams gain an advantage if their opponents must travel east the day before a game. This travel may disrupt the biological clocks of visiting players and impair players' performances on the field.
So, check the travel schedule of your favorite team. Which way do they have to travel? Do they have time to recover before they play? You may be able to predict how your team will perform.

So, if you will be visiting Kazakhstan soon, shake out your shoes before you put them on.

How does memory work? Do memories change over time? Why do we forget?
How can we improve memory? These are a few of the questions answered by
Diane Swanson in her new book called "Hmm?" Swanson fills the 40 pages of
"Hmm?" with trivia, experiments and colorful pictures to help young
students understand memory. Although the book is intended for children,
it discusses many research findings that have been published in scientific
journals and thus can be enjoyed by adults who might be reading to
children, as well. Swanson has a nice way of translating these data into
language that kids can understand. "Hmm?" also contains many memory
demonstrations, experiments and projects that readers can do at home or at
B. "Canine Candy Stripers" in the August 6, 2001 issue of Time magazine discusses how hospitals are using dogs to help people recover after surgery.
C. "Parkinson's Sufferers--Hang in There" in the August 12, 2001 issue of Parade Magazine (the popular Sunday newspaper insert).
D. "Young Cells in Old Brains" in the September issue of Scientific American is a profile of neuroscientist Elizabeth Gould.
E. "The Science of Summer" in the August 27, 2001 issue of Newsweek
magazine discusses the sense of taste and the physiological effects of
A. Compared to humans, houseflies are 10 million times more sensitive to the taste of sugar.
B. Leeches have about 10,000 neurons. (Humans have approximately 100 billion neurons in their brains.)
C. The octopus and squid belong to the class of animals known as the "Cephalopoda" meaning "head-footed."
D. Tarantulas and other spiders sense vibration with hairs on their legs.
E. Slime eels have no eyes, but they do have light-sensitive sensors in
