Beauty in the biased eye of the beholder
When we see a painting, we rate its aesthetic value based upon other artwork we have just seen. ... Read More...
Human perception of colors does not rely entirely on language
Based on the study of a stroke patient with damage to the occipito-temporal brain region, researchers made a big discovery about color categorization. They reveal color categorization and naming can be independent in the human brain. The finding challenges long-standing theories of the mandatory involvement of language in adult human cognition and color discrimination.... Read More...
The case against reality
A new theory argues consciousness creates neural activity, and humans have evolved to see what is needed for survival. Perception, it is argued, is a user interface which may not necessarily be real.... Read More...
When you spot 1 driving hazard, you may be missing another
Subsequent search miss causes a reduction in the ability to detect an additional hazard when they spot another. The findings could help modify driver training to help reduce accidents and to develop in-vehicle technologies that focus on accident reduction.... Read More...
Stimulating neurons to induce particular perceptions in mice’s minds
Using optogenetics, researchers stimulated neurons in the visual cortex of mice to induce illusory images in the animals' minds.... Read More...
Hit it where it hurts: Scientists reveal how mirrors cure phantom pain
Visual responsiveness in the somatosensory cortex diminishes significantly following mirror therapy for phantom limb pain. Before therapy, researchers discovered a strong, unexpected activation in the sensorimotor foot region of amputees to visually presented images of the foot. This response was no longer present following mirror therapy.... Read More...

Facial processing and color processing may engage in similar brain mechanisms.... Read More...
Brains of children with epilepsy able to re-map after surgery to retain visual perception
Following surgery, the brains of children with epilepsy are able to remap and compensate for damaged areas of the visual cortex. The findings shed light on brain plasticity.... Read More...

Researchers reveal what optical illusions tell us about the workings of the brain.... Read More...
A small electrical zap to the brain could help you retrieve a forgotten memory
Using non-invasive transcranial direct current stimulation to target the left rostrolateral prefrontal cortex improves memory retrieval.... Read More...
Brain stimulation enhances visual learning speed and efficiency
Transcranial random noise stimulation (tRNS) helps boost visual learning in patients with chronic cortical blindness, leading to a recovery in motion processing within 10 days of exposure. The effects of the tRNS treatment appear to last for at least six months.... Read More...
