Skin mounted electrode arrays measure neural signals

http://coleman.ucsd.edu/lab-research/ Professor Todd Coleman of UCSD is developing foldable, stretchable electrode arrays that can non-invasively measure neural signals. They can also provide more in-depth analysis by including thermal sensors to monitor skin temperature and light detectors to analyze blood oxygen levels.  The device is powered by micro solar panels and uses antennae to wirelessly transmit or […]

Real-time brain feedback for anxiety disorders

http://news.yale.edu/2013/05/07/research-news-real-time-brain-feedback-can-help-people-overcome-anxiety fMRI-driven neurofeedback has been used in various contexts, but never applied to the treatment of anxiety. Yale University researchers used fMRI to display the activity of the orbitofrontal cortex, a brain region just above the eyes, to subjects in real time.  Through a process of trial and error, the subjects learned to control their brain […]

Computer vision algorithms used to diagnose depression

http://medvr.ict.usc.edu/projects/dcaps/ SimSensei software, developed by Stefan Scherer and colleagues at the University of Southern California, combines computer vision algorithms and the psychological model of depression. An on-screen psychologist asks you a series of questions and watches how you physically respond. Using Kinect, the computer vision algorithms build up a very detailed model of your face […]

Brain scans link math learning abilities to brain structure

http://scopeblog.stanford.edu/2013/04/29/peering-into-the-brain-to-predict-kids-response-to-math-tutoring/ Researchers from the Stanford University School of Medicine used brain scans to look for a link between math-learning abilities and brain structure or function, and compared neural and cognitive predictors of childrens’ responses to tutoring. The analysis of the children’s structural brain scans showed that larger gray matter volume in three brain structures predicted greater […]

Babies’ consciousness, development studied

http://news.sciencemag.org/sciencenow/2013/04/when-does-your-baby-become-consc.html Finding the point at which babies’ reactions change from being purely reflexive to reflecting more intention is leading researches to focus on the first glimmers of conscious thought in infants as young as 5 months old. Ideally, the infant studies would enable scientists to trace a trajectory of how consciousness generates. “You can start […]

Pass-thoughts as the new passwords

http://phys.org/news/2013-04-password-future-passthoughts.html Pass-thoughts are thoughts that a headset records through brainwaves. The computer learns what your individual brainwaves are like and then identifies you. Traditionally, these brainwaves, called electroencephalograms (EEGs), are collected through expensive and sometimes invasive devices, so the pass-thought growth has been severely stunted. Berkeley’s John Chuang and his team conducted a series of […]

A hard look at neuroscience research from The Economist

http://www.economist.com/blogs/babbage/2013/04/neuroscience Sample sizes in neurological research are often too small to draw general conclusions. Marcus Munafo, from the University of Bristol, and his colleagues analyzed hundreds of neuroscience studies to determine their “statistical power”.  If the researchers’ figures are accurate—and if the 12-month period they looked at is representative of neuroscience research in general—then the […]

fMRI differentiates physical from emotional pain

http://www.latimes.com/health/boostershots/la-sci-pain-measure-fmri-20130409,0,5200467.story A group of scientists at the University of Michigan have succeeded in using functional magnetic resonance imaging to tease apart the brain’s consistent response to physical pain from its very similar response to emotional pain. The result is a moving picture of physical pain that allowed the researchers to predict with remarkable accuracy whether the individual […]
