A new study has affirmed the anesthetic drug xenon can help prevent long-term damage associated with traumatic brain injury (TBI). The researchers, from Imperial College London and Johannes Gutenberg University Mainz, have effectively demonstrated in mice that if xenon is administered within a few hours of a TBI it can prevent brain tissue damage that would result in long-term cognitive problems.
With a mouth like a whirlpool full of teeth, the lamprey is not something you'd normally want anywhere near your brain. But now, researchers from the Universities of Texas and Wisconsin-Madison have used molecules taken from the freaky fish's immune system to deliver drugs inside the body – and even managed to sneak them into the brain.
With a good night's sleep being so important to our health, it's not surprising to see so many gadgets designed to deliver us into the Land of Nod. URGOnight is a novel sleep training device designed to improve your ability to get to sleep, and stay asleep, through the use of neurofeedback and brain training. The system, comprising an EEG headset and accompanying mobile app, is currently crowdfunding on Indiegogo.
Researchers from Yale University are suggesting they have homed in on a specific biomarker that can be linked to suicidal thoughts in subjects suffering from post-traumatic stress disorder (PTSD). The new study adds to a growing body of research into novel ways clinicians can identify patients at high risk of suicide.
An intriguing new study, led by scientists from the University of Glasgow, suggests there is a direct causative link between eating a high-fat diet and the development of depression. The new research demonstrates how certain dietary fats can enter the brain, disrupt specific signaling pathways in the hypothalamus, and subsequently induce signs of depression.
A striking new study from Australian researchers has discovered that eating while stressed may lead to greater weight gain than if the same caloric load was consumed in a stress-free environment. The study reveals a molecular pathway activated by stress can alter the body's metabolic processes and lead to increased weight gain.
Scientists have developed an implant that interprets signals in the brain and converts them into understandable, synthesized speech. This innovative piece of technology could one day give a voice to people otherwise unable to communicate.
In a breakthrough study, researchers have managed to restore some brain function in pigs as long as four hours after death. Using a system that pumps preserving chemicals through the brain's circulatory system, the team not only staved off cell death but actually restored some functions like synaptic activity. The astounding discovery raises some ethical questions and may spark new debate about the very definition of death.
