The Neuroscience for Kids "Page of the Month" for June is "Neurosciences on the Internet" at:
"Neurosciences on the Internet" has been on-line since December 1994, making it perhaps one of the oldest web sites devoted exclusively to brain research. Edited and maintained by neurologist Dr. Neil A. Busis, "Neuroscience on the Internet" is a searchable list of hundreds of neuroscience-related web resources. In addition to searching for resources using specific keywords, users can also link to resources that Dr. Busis has grouped according to topics such as diseases, clinical departments, databases, exams, images, newsgroups and mailing lists. "Neuroscience on the Internet" is not just an encyclopedia of links. Rather, the site includes many original contributions on subjects including neurological diseases, brain imaging and the use of the Internet in neurology.
I asked Dr. Neil A. Busis for a "behind the scenes" look at "Neurosciences on the Internet." Here is his reply:
"Neurosciences on the Internet" is a sort of Neuro-Yahoo, a manually
assembled searchable and browsable database of basic and clinical
neuroscience resources on the Web. When I started this project in 1994
there were almost no signposts on the Web to direct people to the types of
resources they desired. The major search engines did not yet exist. I
wanted to help people find valuable Web neuroscience resources. Is the
site obsolete now that HotBot, AltaVista and the other major search
engines have catalogued a huge number of Web sites? I think not. The
general interest search engines often respond to inquiries with an
enormous number of hits, most of them irrelevant. Important results can be
buried many pages deep. In contrast, searches using specialty-specific
topical databases are virtually guaranteed to yield a manageable list of
relevant results. In my database, the entries are all filtered before
inclusion, so the user doesn't have to wade through an impossibly long
list of search results. All entries are also listed on one or more
topic-specific pages. Browsing these pages is a great way to get an
overview of the wonderful neurosciences resources available on the Web
The Nun Study is a project directed by Dr. David Snowdon at the Sanders-Brown Center on Aging at the University of Kentucky in Lexington. The study was started in 1986 and has since received funding from the National Institute on Aging and several private foundations. A total of 678 sisters between the ages of 75 and 103 years have agreed to have annual physical and mental tests and to donate their brains for examination when they die.
Neuroscientists hope that studying the brains of these sisters will reveal clues about the causes of Alzheimer's disease and other neurological disorders. Researchers think that the medical, education and family records of the sisters will help determine if there are specific factors that increase the risk of neurological disease. For example, one long-term study examined writing samples the nuns submitted when they joined the convent. The complexity of these writing samples was related to which of the nuns later developed Alzheimer's disease. Those with the simplest writing styles (list-like as compared with complex prose), were more likely to develop Alzheimer's disease.

Even with warnings from the AAP, many parents still put their babies to sleep on their stomachs. To protect their babies, some parents rely on products that claim to reduce the amount of carbon dioxide that babies rebreathe, even when the babies are placed on their stomachs. Several pediatricians tested some of these devices recently to see if they really work.
The pediatricians measured the changes in carbon dioxide content in a reservoir connected to a mannequin. The mannequin was connected to a pump that simulated breathing. The carbon dioxide content was measured while the mannequin was placed face-down on various products advertised to reduce carbon dioxide rebreathing. The results were compared to carbon dioxide changes when the mannequin was placed with its face to the side.
Of the six products tested, five did NOT reduce carbon dioxide rebreathing adequately. The one device that did work is designed with a fan in the side wall of the mattress. This fan is included to circulate the air around an infant's face.
This study suggests that some products designed to reduce carbon dioxide rebreathing in infants placed on their stomachs do not work as advertised. It is unfortunate that some companies are selling products that may not work. It is especially troubling that these products are sold to parents who buy these devices to protect their children. Further research is necessary to see if the device designed with the sidewall fan can actually reduce deaths due to SIDS.

Margaret Hyde has written more than 80 books on subjects such as asthma, AIDS, outer space, drug abuse, genetics and mental illness. She has teamed with Dr. John F. Setaro to write her newest book called "When the Brain Dies First." In this book, Hyde and Setaro discuss the difficult topic of what happens when the brain dies before the body.
After a brief introduction to normal brain function, "When the Brain Dies First" covers various brain disorders and diseases including shaken baby syndrome, head trauma, brain infections, Alzheimer's disease, Parkinson's disease, Huntington's disease, Batten disease, multiple sclerosis and stroke. The effects of drug abuse and neurotoxins on the brain are also explained.
The many descriptions of patients in the emergency room and operating room help to illustrate disease processes and methods of treatment. Hyde and Setaro are to be congratulated for including recent events that have impacted neuroscience, such as the outbreak of West Nile encephalitis in 1999 and new research into the development of a vaccine for Alzheimer's disease.
Although there is much research that holds the promise of cures for various brain disorders, Hyde and Setaro correctly caution readers about being overly optimistic. They detail the difficult and complex path that leads from the research laboratory to the drug store.
"When the Brain Dies First" does not shy away from difficult and controversial topics. Rather, the book presents a balanced view of euthanasia, brain death, gene therapy and caring for those with dementia. The last chapter of the book deals with keeping the brain healthy and the search for cures to neurological disorders. I was happy to see that Hyde and Setaro mentioned Brain Awareness Week as a time to highlight the progress and discoveries made in neuroscience. "When the Brain Dies First" will serve as a useful book for students in middle and high school who are researching specific neurological disorders and for anyone else interested in what happens when the brain dies before the body.
I asked Margaret Hyde for some background on her new book. Here is her reply:
"John Setaro and I were expressing our concern about several friends and
relatives who were suffering from Alzheimer's and Pick's disease and he
suggested we write a book on the subject. I was surprised to find so many
different kinds of dementia and the large number of families who are
affected. We hope the book will encourage young people to get involved in
prevention, support for patients and families, and perhaps choose careers
in which they do some much needed research toward finding cures."
In this, the third in the popular "Dr. Brain" series by Sierra, one of Dr. Brain's experiments has gone awry. The intellect of Dr. Brain has been transferred to his lab rat, Rathbone. Your mission is to return Dr. Brain's mind by solving the puzzles contained within the various regions of his brain. The now scholarly Rathbone guides you through these in various guises - as Billy Bob Rathbone in the "Neurotransmitter Roundup," as a poetic Rathbone Shakespeare in "Word Surge" and as Rathbot in "Motor Programming," to name a few. While you are formulating your solutions, the good Doctor's niece Elaina oversees your progress, offering up interesting brain facts and alerting you to areas of your own brain that are being stimulated by the task at hand.
Suggestions for Using this Program
While you are attempting the various puzzles associated with their appropriate brain region (music listening and sorting in the temporal region; 3-D image construction and rotation in the occipital region; motor programming in the cerebellum; motor sequencing in the frontal region; etc.), you learn not only which tasks are associated with which brain region, but where your own strengths lie. This game offers many exciting puzzles to explore mathematical, spatial, verbal and motor abilities.
"The Lost Mind of Dr. Brain" is an extremely well thought out game. It is clever, humorous, graphically-exciting and informative; it allows you to use your brain to build and learn about Dr. Brain's brain. This permits you to reflect on your brain's development, structure and function. It just boggles the you-know-what!
I highly recommend this software to supplement the exploration of concepts related to functional brain organization. With nine different brain regions and three levels (novice to genius) for each, this game packs hours of challenging brain- and knowledge-building entertainment.
