(Medical Xpress)—Neuroscientists face a multitude of challenges in their efforts to better understand the human brain. If not for model organisms such as the rat, they might never know what really goes on inside our heads. http://medicalxpress.com/news/2013-03-rats-brains-scientists-previously-thought.html Neuroscience Wed, 27 Mar 2013 09:31:55 EST news283595506 A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces coud help people with severe paralysis control devces with their thoughts. http://medicalxpress.com/news/2013-02-team-unveils-wireless-brain-sensor.html Neuroscience Thu, 28 Feb 2013 11:38:41 EST news281273906 Researchers at the University of Pittsburgh School of Medicine and UPMC describe in PLoS ONE how an electrode array sitting on top of the brain enabled a 30-year-old paralyzed man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to move a robot arm to touch a friend's hand for the first time in the seven years since he was injured in a motorcycle accident. http://medicalxpress.com/news/2013-02-team-bci-spinal-cord-injured-plos.html Neuroscience Fri, 08 Feb 2013 12:42:14 EST news279549718 Scientists at the University of Essex have been working with NASA on a project where they controlled a virtual spacecraft by thought alone. http://medicalxpress.com/news/2013-02-minds-thought-controlled-virtual-spacecraft.html Neuroscience Tue, 05 Feb 2013 07:10:03 EST news279270541 In an ongoing clinical trial, a paralyzed woman was able to reach for and sip from a drink on her own – for the first time in nearly 15 years – by using her thoughts to direct a robotic arm. The trial is evaluating the safety and feasibility of an investigational device called the BrainGate neural interface system. This is a type of brain-computer interface (BCI) intended to put robotics and other assistive technology under the brain's control. http://medicalxpress.com/news/2012-05-paralyzed-individuals-robotic-arms-grasp.html Medical research Wed, 16 May 2012 13:00:15 EST news256390792 Scientists have designed a novel, noninvasive system that allows users to control a virtual helicopter using only their minds, as reported in the online journal PLoS ONE on Oct. 26. The researchers, led by Dr. Bin He of University of Minnesota, created an EEG-based, noninvasive brain-computer interface that allowed users to accurately and continually navigate a virtual helicopter simply by thinking about where they wanted to craft to go. http://medicalxpress.com/news/2011-10-required-scientists-precise-virtual.html Neuroscience Wed, 26 Oct 2011 17:33:37 EST news238869187 (Medical Xpress) -- Seven years after a motorcycle accident damaged his spinal cord and left him paralyzed, 30-year-old Tim Hemmes reached up to touch hands with his girlfriend in a painstaking and tender high-five. http://medicalxpress.com/news/2011-10-spinal-cord-injury-brain-interface.html Medical research Thu, 13 Oct 2011 05:01:21 EST news237700851
