Artificial neural networks decode brain activity during performed and imagined movements.
A theory that has gained considerable attention in international media, including Newsweek and the CBS broadcast 60 minutes, suggest that antidepressant drugs, such as the SSRIs, do not exert any actual antidepressant effect. A research group at the Sahlgrenska Academy has now analyzed data from clinical trials and can rebut this theory.
A drug that is blocked by the EU regulatory system has now been found to improve the quality of life of people with multiple sclerosis, according to a study by Queen Mary University of London.
NPGL, a recently discovered protein involved in brain signalling, has been found to increase fat storage by the body -- even when on a low-calorie diet. In addition, NPGL was shown to increase appetite in response to high caloric food intake, suggesting that perhaps we shouldn't feel so guilty about gorging on junk food from time to time.
New findings challenge existing dogma that neurons release fixed amounts of chemical signal at any one time and could have implications for brain disorders including Parkinson's and schizhophrenia.
A recent study carried out by Dr. Sun Yangang's lab at the Institute of Neuroscience of the Chinese Academy of Sciences discovered a central neural circuit that is critical for transmitting the itch signal. By using optogenetic, chemogenetic, patch clamp recording, and in vivo fiber photometry techniques, the researchers demonstrated that the spino-parabrachial pathway plays a key role in transmitting itch signals from the spinal cord to the brain, and identified the parabrachial nucleus as a first central relay for the itch sensation.
Chemists have discovered a powerful pain reliever that acts on a previously unknown pain pathway. The compound is as effective at relieving neuropathic pain in injured mice as a drug widely used for pain relief called gabapentin. If they can demonstrate that it is safe, effective and nonaddictive in humans -- a process that typically takes years -- the discovery could address one of today's biggest public health challenges: the opioid abuse epidemic.
Working with fruit flies, scientists have identified different labels that attract and control specific nerves. In theory, the 'right' labels may re-form nervous connections if delivered to the site of injury.
Generally, after suffering a concussion, patients are encouraged to avoid reading, watching TV and using mobile devices to help their brains heal. But new research shows that teen-agers who used a mobile health app once a day in conjunction with medical care improved concussion symptoms and optimism more than with standard medical treatment alone.
Researchers have developed a more precise way of diagnosing suicide risk, by developing blood tests that work in everybody, as well as more personalized blood tests for different subtypes of suicidality that they have newly identified, and for different psychiatric high-risk groups. The work, led by the Indiana University School of Medicine, is reported in the journal Molecular Psychiatry.
