The Neuroscience for Kids "Page of the Month" for June is the Virtual Hospital's "The Human Brain: Dissections of the Real Brain" at: http://www.vh.org/Providers/Textbooks/BrainAnatomy/BrainAnatomy.html
The Virtual Hospital is a digital library of medical information developed at the University of Iowa. The nervous system is represented in the library by "The Human Brain: Dissections of the Real Brain."
Click on the "Enter" button to start your visit. The nervous system is
divided into five chapters: 1) the spinal cord, 2) the meninges and blood
vessels, 3) the cerebellum, 4) the brainstem and 5) the cerebral
hemispheres. Each chapter has many photographs of the brain taken at
different angles and planes of section. Each photograph is accompanied by
a brief description and a labeled line drawing to indicate specific
structures and features. "The Human Brain: Dissections of the Real Brain"
can be used to review your neuroanatomy knowledge or just to marvel at the
complexity and beauty of the brain.
Birds sing to protect their territory and to attract mates. The earlier in the morning that a bird can start singing, the better its chances are for success. However, singing is not without danger. In addition to attracting mates, singing birds may attract predators looking for a meal.
Why do some birds start singing earlier in the morning than others? A group of British researchers ventured into the countryside to find out. They measured the eye sizes of 57 types of birds. The scientists then correlated these eye sizes with the time of day that the birds started to sing. They found that birds with big eyes start singing earlier than birds with small eyes. Larger eyes allow more light into the eye and permit vision in low lighting conditions. Scientists believe that birds with bigger eyes can start their day earlier because they can see approaching dangers. Birds with small eyes may not be able to see in the very early morning and may end up on the breakfast menu of a predator.

The National Aeronautics and Space Administration (NASA) announced recently that a schoolteacher will be included in a space mission by the year 2004. The training of teacher-astronauts was cancelled in 1986 after teacher Christa McAuliffe was killed when the space shuttle Challenger exploded. NASA hopes that including schoolteachers in their programs will inspire students in the US to explore careers in science. Sean O'Keefe, the new NASA director, is steering the administration back to basics, including emphasizing science education.
NASA's work in space may seem far removed from what is happening here on Earth. The experiments done in space, however, can tell us a lot about life on Earth. For example, research in space suggests that the brain has an internal model of gravity that allows us to anticipate the effects of gravity. Understanding more about how the brain works could improve safety aboard space shuttles. It is important for astronauts to be able to move precisely when and how they want. Back on Earth, this work may help scientists understand what happens when brain damage affects movement and timing.

It was impossible for me to pass up a book titled "Nibbling on Einstein's Brain." Although "Nibbling on Einstein's Brain" does not focus specifically on neuroscience, it is an excellent introduction to understanding the difference between good science and bad science.
Swanson divides her book into five chapters: 1) Beware of Bad Science, 2) Science Watch, 3) Media Watch, 4) Mind Watch and 5) Winning Strategies. The first chapter introduces readers to the proper way to evaluate scientific articles. Science Watch contains a list of 21 "Baloney Busters" with tips on how to evaluate research with a critical eye. Media Watch lists 11 "Media Alerts" that show how news reports often sensationalize and misrepresent science. Mind Watch lists 18 "Mind Traps" that show how our minds interpret science news we hear and read. The last chapter, Winning Strategies, provides readers with three ways to promote good scientific thinking: question new scientific findings, learn about science and let people know what you think about science.
Do you wonder how Swanson came up with the name of her book? She explains
that experiments done in the 1950s and 1960s investigated "edible
memories." Some scientists thought that if one animal ate another
animal's brain that memories could be passed to the diner. In fact, one
laboratory reported that they could transfer memories this way using
flatworms, rats and goldfish. However, this line of research stopped when
many other researchers were unable to produce similar results.
IMPORTANT NOTE: This movie review reveals some secrets of the movie. So, if you haven't seen "A Beautiful Mind" and want to be surprised, DO NOT READ this review.
I can hardly wait for the video release of "A Beautiful Mind." It should
be in the collection of anyone interested in math or mental illness. The
movie details the adult life of John Forbes Nash, a brilliant and
antisocial Nobel prize-winning mathematician. It also explores his
experience with schizophrenia. The movie is done so cleverly that it is
half over before the viewer realizes that much of what has happened has
occurred only in the mind of the main character. The movie is particularly
sensitive in its handling of the impact that mental illness has on Nash
and his real and imaginary friends and associates. Although "A Beautiful
Mind" is disturbing, it has a wonderful warm and happy ending. High
school and college students learning about neuroscience should find this
movie to be a stimulating introduction to the study of mental illness.
B. "Send in the Roborats" by Michael D. Lemonick (Time magazine, May 13, 2002) and "Enter the Cyborgs" by Nell Boyce (US News and World Report, May 13, 2002) both discuss how rats can be controlled by radio signals sent to their brains.
C. "Sight Unseen" by Michael Abrams (Discover magazine, June 2002): a man's vision is restored but problems remain.
D. "The Complexity of Coffee" by Ernesto Illy (Scientific American, June 2002) discusses the many chemicals that contribute to the flavor and smell of coffee. Also in this magazine is "Islands of Genius" by Darold A. Treffert and Gregory L. Wallace that discusses some of the talents displayed by people with autism.
E. "Cycle of Shame" by Jeff Glasser (US News and World Report, May 20, 2002) reports on the high rate of fetal alcohol syndrome (FAS) in South Africa. Nearly 1 in 15 children suffers from FAS in some parts of South Africa!
F. "The Hidden Mind" is a special issue of Scientific American. This
magazine contains articles by some of the world's top neuroscientists.
One article, "Sex differences in the brain" by Dr. Doreen Kimura, is
online at: http://www.sciam.com/2002/0602mind/0602kimura.html The magazine
is now available on newsstands ($5.95) or online ($5.00) at:
