Drs. Paul Frankland and Sheena Josselyn, both from the Hospital for Sick Children in Toronto, argue this reorganization could have the positive effect of clearing old memories, reducing interference and thereby increasing capacity for new learning. These results were presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN). http://medicalxpress.com/news/2013-05-neuron-formation-capacity-expense-memories.html Neuroscience Fri, 24 May 2013 09:30:03 EST news288605755 Ernie Pyle – an iconic war correspondent in World War II – reportedly said "There are no atheists in foxholes."

After all, it is the accumulation of A-beta that causes the known plaques in the brains of Alzheimer's patients. Starting point for the formation of A-beta is APP. Alessia Soldano and Bassem Hassan (VIB/KU Leuven) were the first to unravel the function of APPL – the fruit-fly version of APP – in the brain of healthy fruit flies. http://medicalxpress.com/news/2013-05-strategy-required-alzheimer-drugs.html Alzheimer's disease & dementia Fri, 24 May 2013 08:42:11 EST news288603723 One of the major frontiers of modern science is a comprehensive understanding of the human brain and its functions to guide the development of new technologies in information and communication.
