""This study is a major advance," says Irene Tracey, a pain neuroscientist at Oxford University who wasn't involved in the study. "It was a tour de force and a welcome addition to understanding this complex and major problem.""
An amygdalar neural ensemble that encodes the unpleasantness of pain http://science.sciencemag.org/content... "Pain is an unpleasant experience. How the brain’s affective neural circuits attribute this aversive quality to nociceptive information remains unknown. By means of time-lapse in vivo calcium imaging and neural activity manipulation in freely behaving mice encountering noxious stimuli, we identified a distinct neural ensemble in the basolateral amygdala that encodes the negative affective valence of pain."
Researchers discover the brain cells that make pain unpleasant http://med.stanford.edu/news/all-news... "Long term, Scherrer aims to confirm that the function of the basolateral ensemble in mice is the same as it is in people, and then down the line, find a safe and effective way to silence the ensemble’s function without interfering with other neurons."
