(PhysOrg.com) -- Computer chip maker Intel wants to implant a brain-sensing chip directly into the brains of its customers to allow them to operate computers and other devices without moving a muscle. http://www.physorg.com/news178186859.html Technology Mon, 23 Nov 2009 08:21:45 EST news178186859 Monetary gain stimulates activity in the brain. Even the mere possibility of receiving a reward is known to activate an area of the brain called the striatum. A team of Japanese researchers report in the January 2010 issue of Cortex, published by Elsevier, the results of a study in which they measured striatum activation in volunteers performing a monetary task and found high-risk/high-gain options to cause higher levels of activation than more conservative options. They also found levels of activation to increase with the amount of money owned. http://www.physorg.com/news177682128.html Medicine & Health Tue, 17 Nov 2009 12:09:50 EST news177682128 In a new study, psychologists at the University of Alabama at Birmingham (UAB) are able to see in detail for the first time how various regions of the human brain respond when people experience an unexpected or traumatic event. The study could lead to the creation of biological measures that could identify people with post-traumatic stress disorder (PTSD) or identify PTSD sufferers who would benefit from specific treatments. http://www.physorg.com/news177085719.html Medicine & Health Tue, 10 Nov 2009 14:50:03 EST news177085719 Common experience tells us that particular scents of childhood can leave quite an impression, for better or for worse.
