New technology bypasses spinal cord and delivers electrical signals from brain directly to muscles A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles -- bypassing the spinal cord -- to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, paralyzed patients. "We are eavesdropping on the natural electrical signals from the brain that tell the arm and hand how to...

Princeton University researchers have used a novel virtual reality and brain imaging system to detect a form of neural activity underlying how the brain forms short-term memories that are used in making decisions. By following the brain activity of mice as they navigated a virtual reality maze, the researchers found that populations of neurons fire in distinctive sequences when the brain is holding a memory. Previous research centered on the idea that populations of neurons fire together...

Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought. Their new study, to be published Sunday, March 4, in the advanced online publication of the journal Nature, shows that through a process...

UK Scientific Group To Study Ethics Of Neurotechnologies

The same technology currently used to help stimulate parts of the brain and help stroke, dementia, and depression patients could be adapted to create weapons that can be fired with a single thought and other non-medical purposes, leading a prominent group of British scientists to open an investigation into the ethical, social, and legal issues surrounding what they refer to as "novel neurotechnologies." One type of this technology, known as deep brain stimulation (DBS), is currently used...

Experts Say Advances In Neuroscience May Affect Future Of Warfare
2012-02-07 14:43:33

As is the fate of nearly all scientific and technological advances, military experts are already prowling for ways to convert recent advances in neuroscience into advantages on the battlefield. And with the science of the brain progressing by leaps and bounds in recent years, ideas for new military technology are already being tossed around that would have been written off as science fiction just a few years ago. In a report published in the UK on Tuesday, a panel of scientists,...

In a new study to appear in Neuron, scientists at the RIKEN Brain Science Institute (BSI) have uncovered mechanisms that help our brain to focus by efficiently routing only relevant information to perceptual brain regions. The results provide valuable insights on how our brains achieve such focus and on how this focus can be disrupted, suggesting new ways of presenting information that augment the brain's natural focal capabilities. Focus on what I am about to tell you! Our complex modern...

Penn-led team develops microelectronic device to map brain activity A team of researchers co-led by the University of Pennsylvania has developed and tested a new high-resolution, ultra-thin device capable of recording brain activity from the cortical surface without having to use penetrating electrodes. The device could make possible a whole new generation of brain-computer interfaces for treating neurological and psychiatric illness and research. The work was published in Nature...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
