University of Pittsburgh researchers have reproduced the brain's complex electrical impulses onto models made of living brain cells that provide an unprecedented view of the neuron activity behind memory formation. http://medicalxpress.com/news/2011-05-brain-cell-networks-recreated-view.html Medical research Wed, 25 May 2011 14:14:18 EST news225551633 Neuroeconomic research at the University of Pennsylvania has conclusively identified a part of the brain that is necessary for making everyday decisions about value. Previous functional magnetic imaging studies, during which researchers use a powerful magnet to determine which parts of a subjects brain are most active while doing a task, have suggested that the ventromedial frontal cortex, or VMF, plays an evaluative role during decision making. http://medicalxpress.com/news/2011-05-region-brain-decisions-economic.html Neuroscience Wed, 18 May 2011 09:38:23 EST news224930251 On a daily basis, our social life places us in situations where we have to decide whether or not to cooperate with others. However, the motivation that encourages us to behave cooperatively is often not clear. Now, new research published by Cell Press in the May 12, 2011, issue of the journal Neuron suggests that anticipation of the feeling of guilt can motivate us to behave unselfishly and reveals a neural mechanism that may underlie this guilt aversion-driven cooperation. http://medicalxpress.com/news/2011-05-good-dont-bad-neural-mechanisms.html Neuroscience Wed, 11 May 2011 12:39:33 EST news224336335 (Medical Xpress) -- Scientists at the University of Glasgow have identified a potential target for the treatment of schizophrenia. http://medicalxpress.com/news/2011-05-potential-schizophrenia.html Medical research Wed, 11 May 2011 08:41:25 EST news224322048
