The Visual Cortex Goes Digital

Cognitive scientist Mark Changizi, from the Rensselaer Polytechnic Institute, is developing pictorial representations of digital circuits which he says can turn our eyes and visual cortex into a powerful, programmable digital computer. Writing in the journal Perception, Changizi explains that harnessing the power of our visual system requires visually representing a computer program in such […]

Brain’s Secondary Depth-Perception Mechanism Uncovered

Humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes this feat. Now, neuroscientists at the University of Rochester have identified a […]

Scan A Brain And Predict The Future

Neuroscientists at Washington University School of Medicine in St. Louis have found they can predict whether test subjects will succeed or fail at a game by scanning their brains. “Before we present the task, we can use brain activity to predict with about 70 percent accuracy whether the subject will give a correct or an […]

Making Sense Of Our Senses

How we perceive someone touching us may depend as much on memory, attention and expectation as on the stimulus itself, say brain researchers from the Howard Hughes Medical Institute (HHMI) writing inNature Neuroscience.

The Eyes Don’t Have It

Color perception is most definitely not in the eye of the beholder, according to researchers at the University of Rochester. Their images of living human retinas show that the number of color-sensitive cones in the retina differs dramatically among people – by up to 40 times. The mystery of why people appear to perceive colors […]
