Since I was a kid, I've been fascinated by 19th century guillotine anecdotes about severed heads winking, attempting to speak, or smiling. The "Guillotine" entry in Wikipedia has a section on "Living heads" and The Straight Dope has investigated the topic as well. And now, two new scientific studies also push on the question of whether the brain is still "alive" after decapitation. From Science News (painting by Francisco de Goya):
Almost a minute after a rat’s head is severed from its body, an eerie shudder of activity ripples through the animal’s brain. (Research published in January by Radboud University Nijmegen neuroscientists suggest that this) post-decapitation wave marks the border between life and death. But the phenomenon can be explained by electrical changes that, in some cases, are reversible, researchers (from the University of Twente in Enschede, the Netherlands) report online July 13 in PLoS ONE.
Whether a similar kind of brain wave happens in humans, and if so, whether it is inextricably tied to death could have important implications. An unambiguous marker could help doctors better decide when to diagnose brain death, knowledge that could give clarity to loved ones and boost earlier organ donation.
"'Wave of death' may not be a last gasp"

Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
