Does the human brain work in the same way when it is at rest as when it is being stimulated? In a paper published in “NeuroImage”, Nicolas Gravel and co-authors report that it does. They find that a new method … Continued
Did you know that your brain is able to read “bar-codes”? In a recently published paper in NeuroImage, Funda Yildirim and colleagues proved this point by mapping the visual cortex purely based on differences in the orientation of small stimulus components. … Continued
