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 ...

Bridging the gap between human memory and perception

The hippocampus may relay predictions about what we expect to see based on past experience to the visual cortex, suggests a human neuroimaging published in JNeurosci. The study is among the first to examine the interaction ...

The unbearable sensation of being

Cindy was cradling her 9-month-old son, Elias, against her chest when she and a room full of family simultaneously yelled "Surprise!" to an unsuspecting aunt on her birthday. The outburst shot like a bolt of electricity through ...

Neuroscience

How does the brain make perceptual predictions over time?

Prediction is crucial for brain function—without forecasting, our actions would always be too late because of the delay in neural processing. However, there has been limited theoretical work explaining how our brains perform ...

Autism-linked protein crucial for feeling pain

Sensory problems are common to autism spectrum disorders. Some individuals with autism may injure themselves repetitively—for example, pulling their hair or banging their heads—because they're less sensitive to pain than ...
