Study provides new evidence supporting the theory that perceptual limitations are caused by a correlated noise in neural activity.
Boundary contraction may be as common as boundary extension, and whether something appears zoomed in or out depends on the properties of the image.
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.
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.
Using optogenetics, researchers stimulated neurons in the visual cortex of mice to induce illusory images in the animals' minds.
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.
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.
