New York: While the human brain tends to shrink with age, men’s brains diminish faster than women’s which may explain why the fairer sex are more likely to stay mentally sharp in their later years, finds a study led by a researcher of Indian-origin. The study noted that the brain’s metabolism slows as people grow […]

New York: Researchers at the Massachusetts Institute of Technology (MIT) have devised a new magnetic resonance imaging (MRI) technique to image calcium activity deep in the brain. Calcium is a critical signalling molecule for most cells, and it is especially important in neurons. Using the non-invasive technique, the researchers can track signalling processes inside the […]

New York: Scientists have found that they can reverse the urge to drink alcohol, finds a study, which may open the door to developing drug or gene therapies to control alcohol addiction. The team at US-based Scripps Research used a laser treatment to temporarily inactivate a specific neuron, which not only reversed alcohol-seeking behaviour but […]

Toronto: Finding it hard to concentrate? Just looking at something that reminds us of coffee can cause our minds to become more alert and attentive, according to a new study. “Coffee is one of the most popular beverages and a lot is known about its physical effects,” said Sam Maglio, Associate Professor at the University […]

London: Researchers have developed an artificial intelligence-based (AI) method for analysis of brain tumours, paving the way for individualised treatment of tumours. According to the study, published in the The Lancet Oncology, AI machine learning methods, carefully trained on standard magnetic resonance imaging (MRI), are more reliable and precise than established radiological methods in the […]

New York: Researchers have found that a gene could help the brain heal itself after a stroke or any other head-related injuries. The study, published in Cell Reports, suggested that a dose of the TRIM9 gene could reduce brain swelling after stroke, prevent damage following a blow to the head (concussion) or encephalitis, which is […]

New York: Biomedical engineers at Duke University have developed an Artificial Intelligence (AI)-based automated process that can trace the shapes of active neurons as accurately as human researchers, that too in a fraction of the time. The new technique, based on using AI to interpret video images, addresses a critical roadblock in neuron analysis, allowing […]

London: Two drugs, in use for treating heart disease and angina, have shown promise in an early trial in preventing stroke and dementia caused by damage to small blood vessels in the brain. The drugs — cilostazol and isosorbide mononitrate — were tested in a group of patients in Britain. The results published in the […]

New York: Researchers have discovered how neurons in the spinal cord help transmit itch signals to the brain. Their findings, published in the Journal of the Mechanical Behaviour of Biomedical Materials, will help contribute to a better understanding of itch and could lead to the invention of new drugs to treat chronic itch, which occurs […]

Singapore: Researchers have found that regular tea drinkers have better organised brain regions and this is associated with healthy cognitive function as compared to non-tea drinkers. “Our results offer the first evidence of positive contribution of tea drinking to brain structure, and suggest that drinking tea regularly has a protective effect against age-related decline in […]

London: Researchers have identified key networks within the brain which they say interact to increase the risk that an individual will think about – or attempt – suicide. Combining the results from all of the brain imaging studies available, the researchers looked for evidence of structural, functional and molecular alterations in the brain that could […]

New York: Although the impact of inhaling polluted air on the lungs is well known, now the researchers have revealed that it can pose a serious threat to brain health as well. The study, published in the journal Chemical & Engineering News, details how researchers are connecting air pollution to dementia, autism and other neurological […]

London: Covid-19 can cause severe neurological complications, including delirium, brain inflammation, stroke and nerve damage, warn researchers. Published in the journal Brain, the research team identified one rare and sometimes fatal inflammatory condition, known as ADEM, which appears to be increasing in prevalence due to the pandemic. Some patients in the study did not experience […]

Washington: Researchers have now claimed that more and more evidence is coming out that people with Covid-19 are suffering from cognitive effects, such as brain fog and fatigue. The study, published in the journal Nature Neuroscience, found that that the spike protein, often depicted as the red arms of the virus, can cross the blood-brain […]
