Researchers identify potential link between serotonin-enhancing drugs and increased risk of cerebrovascular syndrome (stroke). The study suggests that caution should be exercised when combining medications that contain serotonin enhancers, particularly in patients presenting with sudden-onset headaches.
A comprehensive survey of brain death diagnosis in adults worldwide reveals significant variations in procedures, including differences in required physicians, observation time, and confirmatory tests. These discrepancies may be due to collective decisions by task forces or cultural attitudes, highlighting the need for standardization.
A recent study found a significant association between low systolic blood pressure levels (below 130) and cognitive impairment in older patients with heart failure. The researchers suggest that routine management of heart failure should include assessment of cognitive performance to detect early signs of cognitive dysfunction.
A recent study published by the American Academy of Neurology found bupropion SR to be clinically effective for treating neuropathic pain. Approximately three-quarters of patients experienced a 30% reduction in pain symptoms with bupropion SR, while those on placebo saw little improvement.
A recent study by Carnegie Mellon scientists discovered that reading and listening to identical sentences produce systematically different brain activation patterns. The right hemisphere was less active during reading, while the left-hemisphere's pars triangularis region showed increased activation in listening comprehension. This sugg...
A study found that adults with persistent developmental stuttering (PDS) have significantly larger right and left temporal lobes, and more irregularities in brain shape compared to controls. Sex and writing hand preference were also linked to anatomic features.
Researchers compared whole genome activity in trisomy mice brains to normal mice detecting 25,000 genes active, with altered protein manufacturing found in trisomy mice. This study provides a preliminary look at how the whole genome operates in the brain and suggests protein manufacturing could be altered in Down syndrome patients.
Scientists analyzed the magnetic field of the ALH84001 Martian meteorite using a new microscope, revealing that its interior remained cool enough to support life. The findings suggest that microbial life may have traveled from Mars to Earth via the meteorite, but do not prove it.
Research measures health-related quality of life among 'typical' migraine sufferers, showing a strong link between migraine and depression. Forty-seven percent of migraine sufferers experience depression, compared to 17% without migraine.
Elaine M. Hull receives a $602,759 Independent Scientist Award to expand her research on hormone and neurotransmitter interactions in the brain. She aims to clarify how gonadal hormones influence neurotransmitter release in the medial preoptic area, essential for male copulation in all vertebrate species.
A team of six Brown University professors will explore the human brain's function using tiny electronic structures, potentially enabling computers to mimic human capabilities. The five-year grant aims to develop nanotechnology that can stimulate and record brain cells.
Researchers discovered a new receptor site in the brain that causes mice to become obese by storing fat and expending less energy. The study sheds light on genetic determinants of obesity, metabolism, and regulation of fat mass.
Dr. David Suzuki will speak at the Ecological Society of America's annual meeting, discussing his efforts to prevent ecological crises and find ways for humans to live in balance with nature. He focuses on Climate Change and Pacific Salmon Forests, aiming to educate the public about urgent strategies for reducing global warming.
A study of retired football players found that over half had experienced concussions, leading to increased risk of neurological complaints such as memory problems and numbness in extremities. The survey suggests that repeated blows to the head may cause lasting damage, prompting calls for regular testing to monitor player health.
Patients with serious neurological conditions have a better chance of survival in Neurological/Neurosurgical Intensive Care Units (Neuro-ICU) compared to general ICUs. The study, presented at the American Academy of Neurology's Annual Meeting, found a 3.3-fold increase in hospital mortality among patients not in a Neuro-ICU.
Researchers create a new test method that detects nanometer-scale holes, free radicals, and cross-linking in paints, allowing for early detection of damage and more efficient development of durable paints. This breakthrough could lead to cost-effective solutions for bridge coatings and other applications.
Researchers found that brain steroid allopregnanolone mediates many of alcohol's effects, including anti-anxiety and anticonvulsant actions. The study suggests that blocking this compound may inhibit alcohol's sedative-hypnotic effects.
Researchers at Harvard Medical School have coaxed high-level neurons in adult zebra finches to be replaced by their own endogenous precursor cells, demonstrating the potential for brain repair and regeneration.
Researchers used harmonic radar to track honey bees during orientation flights, revealing they learn to navigate by flying faster and visiting more areas. The study suggests that orientation flights allow bees to adapt to new environments, but the scientists still want to know why some bees take more or fewer flights.
Scientists discover that people prefer certain smells when sniffed through one nostril over the other. The left nostril is more accurate for identifying odours, while the right nostril enhances pleasantness perception. This finding fits with brain processing theories and may lead to further research on smell perception.
Researchers found that rats born by Caesarean section showed marked differences in brain development compared to naturally born controls. They had altered dopamine systems and responses to stress tests. The findings hint at a potential link between Caesarean births and schizophrenia risk.
Researchers found that brain areas active during eye movements also control visual attention, shifting focus to peripheral areas. This discovery suggests a shared neural basis for these functions, with potential implications for understanding early mammalian cognition and primate social behavior.
Researchers have found that stunted brain regions may cause severe autism symptoms, while smaller regions may lead to milder symptoms in close relatives. The study used magnetic resonance imaging to compare the brains of identical twins with and without autism.
Scientists successfully used gene therapy to correct deafness in shaker-2 mice by identifying a recessive mutated gene responsible for the condition. The study's findings also revealed that the mutation affects a myosin enzyme involved in inner ear development, which is crucial for hearing.
The symposium brings together experts to present on recent findings in the science of emotion, including how environment impacts brain development and can affect emotional health. Researchers will also share insights into the effects of early nurturing and experiences on emotional memory and trauma.
A team of researchers from Duke University found that the hypoglossal canal, which controls tongue movement, is larger in humans and Neanderthals than in apes and proto-humans. This discovery challenges the theory that human speech may not have arisen until around 40,000 years ago.
A recent study has found a link between methylmercury exposure in pregnant mothers and neurological delays in 7-year-old children. The research, conducted in the Faroe Islands, used sophisticated neuropsychological and neurophysiological techniques to examine the effects of prenatal mercury exposure on brain development.
A study using brain scans found that structures on the right side of the brain are involved in anxious thoughts and processing new inputs. The right frontal lobe, basal ganglia, cerebellum, and pontine nuclei were identified as key areas.
A new study by German neurologists found that transcranial color-coded duplex sonography (TCDS) is 90% effective in distinguishing between ischemic and hemorrhagic strokes under emergency treatment conditions. TCDS can accurately diagnose stroke type in most cases, making it a fast and reliable option for acute stroke treatment.
A recent study by American Heart Association found that risk of stroke after heart attack is highest within five days. The research highlights atrial fibrillation and ST elevation as key factors increasing likelihood of a heart attack-related stroke.
