...technique, which generates high resolution pictures, has also revealed surprising precision of brain cell organization in the visual cortex of cats...
...colleagues have shown that the brain's ability to use glucose drops off dramatically after being awake 24 hours, indicating a decrease in brain activity--despite the fact that there's still plenty of glucose available. The biggest drops occur in exactly those areas of the cortex that anticipate and integrate emotion and reason. After 24 hours, however, the drop-off stabilizes. "But performance doesn't level off," Belenky notes. "It continues to tank." Why? No one knows...
...study, conducted at Yale University, suggests that racial bias can be found in the amygdala, a region of the brain involved in emotional response, before it is censored by the frontal cortex and the conscious brain...
...from waiting for more research, Huang is branching out. Eighteen months ago he began performing the surgery on patients suffering from the degenerative disease ALS, better known as Lou Gehrig's disease. ALS kills most victims within five years. By transplanting OEG cells to just below the cortex of the brain and in the spine, Huang claims to have slowed the progress of the disease in "several" of his 40 patients, and offers video evidence of one who regained the ability to walk. Another patient, Chicago-based playwright Ben Byer, was diagnosed with ALS in 2002 and underwent surgery...
...Affairs Health System, the University of Michigan and Princeton, the subjects were given harmless but frequently painful electric shocks and then provided with what they were told was a pain-relieving cream. After the bogus cream was applied, nerve activity in the brains of the volunteers changed. The prefrontal cortex, involved in easing pain, became more active, while regions involved in sensing pain quieted down. When it comes to feeling less pain, it seems, you gotta believe...
