In December, 26 new figures were added and 127 pages were modified.
The Neuroscience for Kids "Page of the Month" for January is "Global Anatomy" at:
Although "Global Anatomy" was created for first-year medical students, Neuroscience for Kids readers should also find this web site useful. Created in 1997 by the Department of Anatomy at the University of Wisconsin Medical School, "Global Anatomy" is a series of Internet textbooks about neuroanatomy. The main sections of the site focus on the cranial nerves, spinal cord, brainstem, cerebellum and thalamus. These areas are described in detail and illustrated with photographs and drawings. There are some challenging quizzes to test your neuroanatomy knowledge -- a great way to prepare for your next test!

Capstone Press (http://www.capstone-press.com/) has already donated some books as prizes. There are many prizes for students in each grade category. Perhaps you can be a winner!
A. Have a speaker visit your class. Visit the Society for Neuroscience Committee on Neuroscience Literacy web site to find a neuroscientist who is interested in K-12 education:
Contact the neuroscientist to set up a visit as soon as possible because things can get very busy during the BAW.
B. Plan a BAW Open House or a Brain Science Fair. Students could conduct experiments and then present their results to other students, teachers and parents. You could announce your event using electronic BAW postcards: http://faculty.washington.edu/chudler/post/baw.html
C. Learn about the brain in class. You can find a one-week lesson plan for BAW and many experiments and demonstrations on the Neuroscience for Kids web site.
One-week BAW lesson plan:
One month of short activities:
Experiments, activities and demonstrations:
The Society for Neuroscience and
DANA Alliance have other
BAW materials for you to use. Visit these web sites to find out what is
going on near you during BAW. You may find a field trip, lecture or open
house to attend.
"Last week my brain was scanned using magnetic resonance imaging (MRI). I was told to remove all metal I was carrying or wearing and then I was placed on my back on a gurney and rolled into the MRI machine. The MRI technician told me not to move or the quality of the images would be poor.
Once I was in the machine, the technician placed a cloth over my eyes. I am not quite sure why she did this, but it was a little soothing and I didn't have to look at the machine. The sounds of the MRI were loud, excruciating...and they never stopped. The lab technician told me the noise was the machine taking images of my brain in various positions.
While the machine was working, I recited the Gettyburg Address to myself to help pass the time. I also recalled the poem "Annabelle Lee" by Edgar Allen Poe and various nursery rhymes. I only wished I knew more of them. As a last resort I counted up to 100 and then counted backwards. By the time I finished counting, I thought I couldn't take the noise any longer and called for the technician who was standing close by. She kept asking me if I was "ok." I asked her how much longer I had to stay in the machine as I didn't think I could take the noise much longer. She said to hold on for one minute longer. Of course, it was a little longer than one minute.
The entire process took about 20 minutes. It was not painful, but the noise was terrible. I'll never forget the noise!"
We won't know the results of the MRI for a few weeks. However, my dad
managed to get copies of his brain scans which he promised to give to me.
Although many experiments have studied what people dream about, few experiments have investigated the emotional content of dreams. New research from Norway sheds light on the emotional experiences contained in dreams. Nine volunteers were connected to portable EEG machines as they slept in their own homes. The EEG machine was used to record brain waves and to show researchers when the volunteers were in REM sleep. Volunteers were awakened when their EEG signaled to the researchers that REM sleep was occurring. Once awake, the volunteers were asked to fill out a report noting the appearance of emotions in their dreams.
Emotional content within a dream was reported 74% of the time when people were awakened from REM sleep. Sometimes people reported more than one type of emotion within a single dream. The most common emotion found in dreams was joy/elation (36% of the reports). The second most common emotion was surprise (24% of the reports), followed by anger (17% of the reports).
It is well known that the limbic areas of the brain are involved with the experience of emotions and that these areas are active during REM sleep. How these brain areas contribute to the emotional content of dreams and why people experience these emotions while asleep is not known.
I'd like to know how "emotional" the volunteers in this experiment were during the morning after the experiment. How would you like to be awakened each time you started to dream?
