Link Between Touch And Emotion Discovered
2012-06-05 04:36:07

Connie K. Ho for redOrbit.com Sight. Sound. Touch. These are just a few of the senses that the body has. This theme of senses was the subject of a recent study by neuroscientists from the California Institute of Technology (Caltech) who reported a relationship between touch and emotion via the brain´s primary somatosensory cortex. The findings, described in a recent issue of the Proceedings of the National Academy of Sciences (PNAS), were discovered by researchers Valeria Gazzola...

Researchers at the RUB and from Durham report Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly. Neural pathways that simultaneously process information from different senses are responsible for this effect. "We have embarked on a whole new therapy approach" says PD Dr....

Two Blind Men Receive Some Sight Through Eye Implants
2012-05-04 05:05:10

Two blind men have received sight for the first time in years due to new advances in medical science. The Oxford Eye Hospital and King's College Hospital in London have been carrying out a clinical trial that helps restore sight to the blind, at least partially, through eye implants. Chris James and Robin Millar lost their vision due to a condition known as retinitis pigmentosa, which is when the photoreceptor cells at the back of the eye eventually cease to function. A 0.12-inch...

Women Have Bigger Pupils Than Men

From an anatomical point of view, a normal, non-pathological eye is known as an emmetropic eye, and has been studied very little until now in comparison with myopic and hypermetropic eyes. The results show that healthy emmetropic women have a wider pupil diameter than men. SINC Normal, non-pathological emmetropic eyes are the most common type amongst the population (43.2%), with a percentage that swings between 60.6% in children from three to eight years and 29% in those older than 66....

How Your Eyes Deceive You
2012-04-24 05:02:24

People rely on their eyes for most things they do — yet the information provided by our visual sensing system is often distorted, unreliable and subject to illusion. Researchers at The Vision Centre, Australia, are throwing new light on the tricks the brain plays on its owner as it struggles to make sense of the visual and other sensory signals it constantly receives. “We tend to regard what we see as ℠the real world´,” says Dr Isabelle Mareschal, a...

Scientists funded by the Medical Research Council (MRC) have shown for the first time that transplanting light-sensitive photoreceptors into the eyes of visually impaired mice can restore their vision. The research, published in Nature, suggests that transplanting photoreceptors — light-sensitive nerve cells that line the back of the eye — could form the basis of a new treatment to restore sight in people with degenerative eye diseases. Scientists from UCL Institute of...

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness. Researchers increased the resistance of optic nerve cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitudes. The stress of the intermittent low-oxygen environment induces a protective response called...
