Brain networks change according to cognitive task
Using a newly released method to analyze functional magnetic resonance imaging (fMRI), Northwestern University researchers have demonstrated that the interconnections between different parts of the brain are dynamic and not static. This and other findings answer longstanding debates about how brain networks operate to solve different cognitive tasks. They are presented in the current (June 1) iss...Men and women differ in brain use during same tasks
The comedians are right. The science proves it. A man's brain and a woman's brain really do work differently. The study involved volunteers who performed memory...Mice learn tasks that may help treat human psychiatric disorders
Mice that couldn't be dissuaded from the object of their attention by a piece of sweet, crunchy cereal may help researchers find new treatments and cures for human disorders like autism and Parkinson's disease. For the first time, a psychiatric test for monitoring many human mental abnormalities has been adapted for use in mice, according to researchers at Purdue University, University of...Master planners in brain may coordinate other areas' roles in cognitive tasks
Scientists have used data from scans of 183 subjects to identify brain areas that consistently become active in a variety of cognitive tasks, such as reading, learning a rhythm or analyzing a picture. If the brain in action can be compared to a symphony, with specialized sections required to pitch in at the right time to produce the desired melody, then the regions highlighted by the new s...Neural bottleneck found that thwarts multi-tasking
Many people think they can safely drive while talking on their cell phones. Vanderbilt neuroscientists Paul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. "Why is it that with our incredibly complex and sophisticated brain, with 100 billion neurons processing information at rates of up to a thousand times a se...Improving the Efficiency of Common Filtration Tasks in your Laboratory

Sleep deprivations has been used to test the importance of sleep for memory and learning. It is difficult to interpret because of side effects, such as fatigue and reduced alertness. A study conducted on sleep-deprived patients by circumventing these complications by allowing recovery sleep by Harvard Medical school researches. Subjects who were sleep deprived on the first day showed no...Indian Government Sets Up Task Force For Avian flu
The government of India is closely watching the ‘Avian Flu’ that is spreading through migratory birds from China. //It has now formed a task force to tackle this emergency. The task force is headed by Cabinet Secretary B.K.Chaturvedi and includes secretaries of health, environment, animal husbandry and agriculture ministries. The inter-ministerial task force is to formulate guidelines on...Task Learning Made Simple By Taking Short Breaks
While attempting to learn a new task, taking short breaks can go a long way in making it sound simple and easy, according to a new study conducted by Massachusetts Institute researchers. // Scientists David Foster and Matthew Wilson, working at the Massachusetts Institute of Technology in Cambridge, found that rats' brains 'replay' their experiences in reverse when the animals pause b...Task Force Set Up By PM To Fill Up The Healthcare Sector
Prime Minister Manmohan Singh set up a task force to fill up the healthcare sector, which runs shortage of doctors, nurses and lab technicians. The recruitment not only fills // up the void but also give an opportunity to the unemployed. The move is based on the recommendations of a recent report submitted by National Commission on Macroeconomics and Health, highlighting the huge gap in...
