Sound changes the way rodents sense touch

The brain assigns sensory information from the eyes, ears and skin to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these ...

How the brain reacts to loss of vision

If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organisation of the cerebral cortex and on memory ability. This is the conclusion drawn by researchers ...

Tuning arousal to boost information transmission in the brain

Columbia neural engineers discover a mechanism by which the locus coeruleus modulates information processing in the thalamus; their findings of how sensory information is encoded in the healthy brain may lead to new treatments ...

Unpacking pain: what causes it and why it's hard to measure

Pain is difficult to measure. Unlike using a thermometer to measure body temperature, a blood test to measure blood glucose, or a magnetic resonance imaging (MRI) scan to detect a tumour, there are no instruments or tests ...

Neuroscience

A new model for how working memory gets you through the day

Important because it is mundane, working memory gets us through every day by allowing us, for instance, to follow the receptionist's directions to find the doctor's office, or to sort through the costs and benefits of one ...

Neuroscience

Study reveals how the brain overcomes its own limitations

Imagine trying to write your name so that it can be read in a mirror. Your brain has all of the visual information you need, and you're a pro at writing your own name. Still, this task is very difficult for most people. That's ...

Neuroscience

Another step toward the hand prosthesis of the future

Researchers stimulated the nerves of an amputated arm with signals very similar to the natural ones, succeeding in "imitating the colors" of the evoked sensations of the various types of receptors and related nerve fibers ...
