The brain is the most difficult part of the body to assess especially the level of signaling molecules called cytokines. Cytokines are secreted by glial cells, which could make up nearly 90% of all brain cells. Cytokines play a key role in controlling moods, cognition and behavior, which directly influences mental health.
CSF is a clear fluid which cushions the brain and spinal cord and clears waste from the brain. If it leaks into the nostrils or throat, one could sense a metallic taste. CSF rhinorrhea can cause severe complication named bacterial meningitis where the lining of the brain and spinal cord gets inflamed.
A new generation of brain scanner, that can be worn like a helmet allowing patients to move naturally whilst being scanned, has been developed by researchers at the Sir Peter Mansfield Imaging Centre, University of Nottingham and the Wellcome Centre for Human Neuroimaging, UCL. It is part of a five-year Wellcome funded project which has the potential to revolutionize the world of human brain imaging.
A study using epilepsy patients undergoing surgery has given neuroscientists an opportunity to track in unprecedented detail the movement of a thought through the human brain, all the way from inspiration to response.
Recent decades have seen an "explosive evolution" of techniques to restore blood flow to areas of the brain endangered by stroke or clogged arteries, according to a report by Loyola Medicine neurologists and neurosurgeons.
People who experience frequent migraines may soon have access to a new class of drugs. In a pair of large studies, two drugs that tweak brain circuits involved in migraine each showed they could reduce the frequency of attacks without causing side effects, researchers report in the New England Journal of Medicine.
While Zika virus causes devastating damage to the brains of developing fetuses, it one day may be an effective treatment for glioblastoma, a deadly form of brain cancer. New research from Washington University School of Medicine in St. Louis and the University of California San Diego School of Medicine shows that the virus kills brain cancer stem cells, the kind of cells most resistant to standard treatments.
Researchers at the Howard Hughes Medical Institute (HHMI) in the US have developed new silicone probes, Neuropixels, to simultaneously monitor the activity of multiple neurons from multiple brain regions.
