Old memory traces in brain may trigger chronic pain
... ... A Northwestern University researcher has found a key source of chronic pain appears to be an old memory trace that essentially gets stuck in the prefrontal cortex, the site of emotion and learning. The brain seems to remember the injury as if it were fresh and c...SCAI'S Hildner Lecture traces progress through 30 years of interventional cardiology

CHICAGO--When pioneering interventional cardiologists introduced angioplasty and stenting more than 20 years ago, few could have imagined that, one day, severely diseased coronary arteries would be propped open virtually end-to-end with tubular metal scaffolding. Fewer still could have envisioned how to dismantle that mesh support system once the artery healed. ...... Dr. Richard S. Stack, profes...Brain researchers discover the evolutionary traces of grammar
Researchers found that simple language structures are processed in an area that is phylogenetically older, and which apes also possess. Complicated structures, by contrast, activate processes in a comparatively younger area which only exists in a more highly evolved species: humans. These results are fundamental to furthering our understanding of the human language faculty. (PNAS, February 6, 200...
