Brain Represents Tools As Temporary Body Parts, Study Confirms
Researchers have what they say is the first direct proof of a very old idea: that when we use a tool-even for just a few minutes-it changes the way our brain represents the size of our body. In other words, the tool becomes a part of what is known in psychology as our body schema, according to a report published in the June 23rd issue of Current Biology, a Cell Press publication.

How The Body Differentiates Between A Scorch And A Scratch
You can tell without looking whether you"ve been stuck by a pin or burnt by a match. But how? In research that overturns conventional wisdom, a team of scientists from the California Institute of Technology (Caltech) and the University of California, San Francisco (UCSF), have shown that this sensory discrimination begins in the skin at the very earliest stages of neuronal information processing, with different populations of sensory neurons--called nociceptors--responding to different kinds of painful stimuli.

Minor League Hockey Players Unable To Identify Concussion Symptoms, Study Says

When Chicago Blackhawk"s leading scorer Martin Havlat returned to the ice for game four of the Western Conference Final after sustaining a concussion only two days earlier, questions were raised surrounding his swift return. According to a new study by St. Michael"s Hospital neurosurgeon Dr. Michael Cusimano, similar questions were raised by 25% of minor league hockey players who did not know if an athlete with symptoms of a concussion should continue to play hockey. Nearly a majority of these players were also unable to identify a concussion or its related symptoms. The findings are part of a study by Dr. Cusimano that analyzed the concussion knowledge of 142 adults (coaches, trainers and parents) and 267 players from GTA Atom (10-years-old), Bantam (14-years-old), AA (highly competitive) and house league divisions. The study is published in the May edition of the Canadian Journal of Neurological Sciences. "Serious misconceptions exist among minor league hockey players, athletes, coaches and parents when it comes to understanding the signs and symptoms of a concussion and its treatment," said Dr. Cusimano, a professor of neurosurgery, education and public health at the University of Toronto and vice-president of ThinkFirst Canada, a national injury prevention organization. "While many can identify how a concussion may occur, most cannot identify the symptoms and are under the impression that concussions can be treated with physician-prescribed medication or physical therapy. Many also believe it"s okay to return to play before they have fully recovered from such a brain injury. This is troublesome since repeated brain injuries can lead to long term effects in functions such as memory, behaviour, mood, social relations and school or work performance." Key findings of the study include: * Up to two thirds of players had the mistaken impression that a player does not have to lose consciousness to have suffered a concussion * A quarter of adults and up to half of children could not identify any symptoms of a concussion or could name only one symptom of a concussion. * About one-half of players and a fifth of adults mistakenly believed concussions are treated with medication or physical therapy * About a quarter of all players did not know if an athlete experiencing symptoms of a concussion should continue playing * About 4 in 10 of younger players and 3 in 10 of the older players thought a concussed athlete could return to play when feeling "90% better" or "while experiencing a mild headache for the next game as long as it"s at least two days later." In Canada, ice hockey is the main cause of sports-related traumatic brain injury. Statistics suggest youth 5-17 have about 2.8 concussions per 1,000 player-hours of ice hockey while university and elite amateur players sustain rates of 4.2 and 6.6 concussions per 1,000 player hours. Concussions have forced many NHL players like Brett Lindros and Pat LaFontaine to retire early and others like Eric Lindros and goalie Mike Richter to stay off the ice for an extended time because of repeated head injuries. Concussions can have cumulative and lasting effects on memory, judgment, social conduct, reflexes, speech, balance and co-ordination. Key to preventing repeated injuries is to recognize the symptoms of concussion when they occur and knowing how to deal with their effects. "Motivation to win, the wish to advance in their sport and earning the acceptance of their team-mates often outweigh an athletes" decision, or their parents" or coaches" decision, to play safe. This mind-set, coupled with the influence of media and behaviour of some parents, coaches and officials, unfortunately send a clear message that it is more important to continue to play injured than take someone out of the game," said Dr. Cusimano. "This "win at all costs" attitude places added responsibility on parents, coaches and medical professionals to recognize symptoms of a concussion and take all necessary steps to ensure a culture of healthy attitudes and behaviours among players and in leagues." Changes in rules such as removing fighting and body checking, proper use of helmets, softer shoulder and elbow pads, improved enforcement of rules, educational efforts and recognizing the critical role that professionals and the media have in shaping the culture of the sport would be beneficial, he added.
