Why the eye could be the window to brain degeneration such as Alzheimer’s disease

Researchers from Queen’s University Belfast have shown for the first time that the eye could be a surrogate for brain degeneration like Alzheimer’s disease (AD). This research results have recently been published in the Journal of Ophthalmic Research and is the first clinical study showing a potential for peripheral retinal imaging to be used in monitoring AD and potentially other […]

‘Antifreeze’ molecules may stop and reverse damage from brain injuries

The key to better treatments for brain injuries and disease may lie in the molecules charged with preventing the clumping of specific proteins associated with cognitive decline and other neurological problems, researchers from the Perelman School of Medicine at the University of Pennsylvania report in a new study published in Neurobiology of Disease. Concentrations of these brain molecules—called N-acetylaspartate (NAA) […]

Scientists discover how brain signals travel to drive language performance

Effective verbal communication depends on one’s ability to retrieve and select the appropriate words to convey an intended meaning. For many, this process is instinctive, but for someone who has suffered a stroke or another type of brain damage, communicating even the most basic message can be arduous. Scientists know that a brain region called the left inferior frontal gyrus […]

Alzheimer’s breakthrough: Brain metals that may drive disease progression revealed

Alzheimer’s disease could be better treated, thanks to a breakthrough discovery of the properties of the metals in the brain involved in the progression of the neurodegenerative condition, by an international research collaboration including the University of Warwick. Dr. Joanna Collingwood, from Warwick’s School of Engineering, was part of a research team which characterised iron species associated with the formation […]

Brain tingles—first study of its kind reveals physiological benefits of ASMR

Autonomous sensory meridian response (ASMR) – the relaxing ‘brain tingles’ experienced by some people in response to specific triggers, such as whispering, tapping and slow hand movements – may have benefits for both mental and physical health, according to new research. In the first study of its kind into the physiological underpinnings of ASMR, researchers from the University of Sheffield […]

Rhesus macaque model offers route to study Zika brain pathology

Rhesus macaque monkeys infected in utero with Zika virus develop similar brain pathology to human infants, according to a report by researchers at the California National Primate Research Center and School of Veterinary Medicine at the University of California, Davis, published June 20 in Nature Communications. Rhesus macaques may be a suitable model system to study how Zika virus infection […]

Researchers investigate changes in white matter in mice exposed to low-frequency brain stimulation

A team of researchers at the University of Oregon has learned more about the mechanism involved in mouse brain white matter changes as it responds to stimulation. In their paper published in Proceedings of the National Academy of Sciences, the group describes the experiments they conducted and what they found. Prior studies of the brain have shown that white matter […]

Electrically stimulating the brain may restore movement after stroke

UC San Francisco scientists have improved mobility in rats that had experienced debilitating strokes by using electrical stimulation to restore a distinctive pattern of brain cell activity associated with efficient movement. The researchers say they plan to use the new findings to help develop brain implants that might one day restore motor function in human stroke patients. After a stroke, […]
