F. February Neurocalendar
G. Helmets for the Slopes?
In January, 24 new figures were added and 64 pages were modified.
The Neuroscience for Kids "Page of the Month" for February is the "Virtual Neurophysiology Lab" from the Howard Hughes Medical Institute at:
Step right into the Virtual Neurophysiology Lab (VNL) to explore the sensory system of the leech. Before you enter the lab, make sure that you have the Macromedia Shockwave plugin for your browser. If you don't have Shockwave, you can get it through a link at the VNL.
Your tour of the lab starts with the laboratory set-up where you can learn more about the leech and the equipment you will use in the VNL. Your leech is waiting for you at the bottom of a frame on the left side of your monitor.
Click on the "enter" sign to get into the lab and watch as your equipment floats into position. Click on the dissecting tongs and follow the directions under the picture to pin your leech to the tray. You will be directed through several more steps to prepare the leech for recording from nerve cells.
Once your leech is ready, you can test neurons by stroking the skin of the leech with a probe, forceps, and a feather. You can also see what a particular neuron looks like by injecting it with dye. Your job is to identify the type of neuron from which you are recording an electrical impulse. To do this, you must compare the shape and response of the neuron to several examples of neurons found in the leech.
The file sizes of these pages are quite large (> 100 KB) so downloads may be slow through your modem. Therefore, you may have to wait between steps as you go through the different procedures in the experiment. However, the VNL is an entertaining and interactive introduction to neurophysiology and best of all, you don't have to pick up a real leech.
Both the DANA Alliance and the Society for Neuroscience have on-line BAW calendars that list events going on across the country. If you are still trying to find BAW events, these calendars may list activities near you. If you already have plans, let the DANA Alliance know what you are doing.
The DANA Alliance calendar is located at:
The Society for Neuroscience Brain Awareness Week page is located at:
Here in Seattle we have scheduled public lectures and visits to classes. On March 17th, a University of Washington BAW Open House for about 300 students will feature the Pacific Science Center/Group Health Cooperative "Brain Power Team" which will present a 45 minute "Brain Power" show. Students will also work with hands-on, interactive exhibits set up and staffed by researchers at the university. For more on activities in the Seattle area, see:
Let me know what is going on in your area. I can always use new ideas.

Big Head is a visual treat with its rich informative content on the scientific aspects of the brain. Dr. Rowan, a physician, uses a unique artistic approach to illustrate this book with life-sized and see-through realistic pages. The cover's inner flap poses questions to the reader to stimulate interest. The journey begins through the discovery of the different parts of the brain and the functions they control. Lift-off acetate pages and hands-on experiments enhance the basic information.
Each topic is discussed on two information-filled pages highlighted by colored boxes with facts related to the main text. Photographs of a child also appear on each main section to portray the ratio of specific brain parts to the whole head. Colorful detailed illustrations enhance the interaction between the reader and the author. Dr. Rowan goes beyond neuroanatomy and includes such information as the importance of dreams and their relationship to the subconscious. For readers who are curious about the brain's functions, this is a good introduction and an engaging start.
Head and brain injuries caused by skiing have been in the spotlight since celebrities Sonny Bono and Michael Kennedy died in ski accidents about one year ago. Although skiing and snowboarding are generally safe sports, improvements in ski equipment and snow grooming methods have allowed people to ski faster. Recreational skiers can reach speeds of 40 miles per hour. Most ski injuries occur when people ski too fast, get out of control, and hit fixed objects like rocks or trees.
For a news story on the ski accidents of Bono and Kennedy, see:
So how can injuries to skiers and snowboarders be prevented and reduced? Here are some suggestions:
A. Slow down!
B. Ski and snowboard under control!
C. Ski area operators should pad lift towers, trees and other objects on the slopes.
D. Ski area operators should label all trails carefully so inexperienced skiers and snowboarders stay off steep terrain.
E. As the CPSP recommends, "Wear a helmet."
It is believed that Chess has its origins in a game called "chatuanga," invented in India around 600 AD. In the last 1,400 years, chaturanga has undergone changes and is now known as chess. Psychologists, physiologists, neurologists and other neuroscientists have taken an interest in how playing chess affects the brain. Some brain researchers believe that playing chess requires mainly the right side of the brain because the game requires non-verbal, visual/spatial and pattern recognition skills. The right hemisphere of the brain is dominant for both visual/spatial and pattern recognition skills.
Some world-class masters have played chess while connected to machines that record brain waves. In general, these chess masters had brain waves just like everyone else. The only difference in the brain waves of some players was a slight change in "alpha wave" activity that may indicate that they were a bit more relaxed.
Two studies have used brain imaging methods to look at brain function while people played chess. In one study (Nature, 396:191, 1994), researchers found that the left temporal lobe and left hippocampus were activated when players were shown a chess board and asked "Can the white knight capture a black rook?" When players were shown a chess board and asked if checkmate could happen in one move, the prefrontal cortex and an area near the border of the parietal and occipital cortex on both sides of the brain were active.
Another study (Neuroscience Letters, 198:169-172, 1995) examined brain blood flow in expert chess players. When right-handed players had to solve a complex chess problem, blood flow to the right prefrontal cortex and right middle temporal lobe increased.
These types of experiments are important because they help to determine how the brain is involved with problem solving, planning and memory. Data from these studies may also provide clues about treatment for people who suffer brain injuries that impair higher cognitive functions.
The cover story of Newsweek Magazine (January 11, 1999) discussed new discoveries on the causes and treatments of migraine headaches.
B. Percentage of total cerebral cortex volume (human): frontal lobe = 41%; temporal lobe = 22%; parietal lobe = 19%; occipital lobe = 18%. (Statistics from Caviness Jr., et al. Cerebral Cortex, 8:372-384, 1998.)
C. People can distinguish between 3,000 and 10,000 different smells.
D. Schizophrenia affects about 1 out of every 100 people.
E. Bees and butterflies can see ultraviolet light.
