KQED QUEST never lets me down, here’s a good story on neuropyschology-research at Stanford using MRIs…the same technique used by our upcoming speaker, Dr. Phillipe Goldin. In this story, they are studying how children with various levels of reading skills have different neural patterns.
With the fMRI, the subject has to stay still for upwards of 45 minutes in the machine. The fMRI does only measure blood flow rates, which by all accounts is only one useful measure of brain activity. Nonetheless, this is a fascinating methodology with great potential for our understanding of basic neural processes.

This past weekend, 6 DtaS attendees strapped on their boots and hit the trail. Considering the recent 5.6 quake last week, what better time to learn about faults here in the Bay Area?
Six of us hit the dusty trail in Los Trancos Open Space Preserve. It was a docent led hike and our leader was quite knowledgeable. Over the course of the 2-3 mike hike (click the link to see a virtual tour of the hike), we were learned about basic earthquake science, with a eye on the 1906 quake. Many after effects of the 1906 quake were still visible, from tree trunks growing sideways to flat earthquake “benches” formed on the side of the hill. Most fascinating was the view from the hillside…you could see how the San Andreas snaked toward San Francisco, especially into Crystal Spring reservoir.
This hike is offered once a month. Check out the calender on Los Trancos’ website for more information.
