Three Cell Types Help the Brain Tell Day From NightNews
Salk researchers identify light-sensitive cells in humans that appear to help establish healthy day-night cycles.
To Get More Oxygen to the Brain, Just BreatheNews
Contrary to accepted knowledge, blood can bring more oxygen to mice brains when they exercise because the increased respiration packs more oxygen into the hemoglobin, according to an international team of researchers who believe that this holds true for all mammals.
A Week in the Dark Alters Mouse Brain Networks and HearingNews
Scientists have known that depriving adult mice of vision can increase the sensitivity of individual neurons in the part of the brain devoted to hearing. New research has revealed that sight deprivation also changes the way brain cells interact with one another, altering neuronal networks and shifting the mice's sensitivity to different frequencies.READ MORE
Teaching People To Control Their Brainwaves Can Boost Their Attention, TooNews
Having trouble paying attention? MIT neuroscientists may have a solution for you: Turn down your alpha brain waves. In a new study, the researchers found that people can enhance their attention by controlling their own alpha brain waves based on neurofeedback they receive as they perform a particular task.
Antibodies defend the body against bacterial, viral, and other invaders. But sometimes the body makes antibodies that attack healthy cells. In these cases, autoimmune disorders develop.READ MORE
Innately, we pull our hand away when we touch a hot pan on the stove, but little is known about how our brain processes temperature information. Northwestern University scientists now have discovered how a fruit fly's brain represents temperature, mapping it neuron by neuron, which has implications for understanding the much more complex human brain and how it responds to sensory stimuli.READ MORE
Study findings contradict prevalent theory, suggest new treatment strategy A study from researchers at Massachusetts General Hospital (MGH) and Brigham and Women's Hospital (BWH) reveals for the first time exactly how mutations associated with the most common form of inherited Alzheimer's disease produce the disorder's devastating effects.READ MORE
Researchers at the University of Illinois at Chicago (UIC) have identified a genetic variation that in women significantly increases their risk of developing multiple sclerosis (MS).READ MORE
Evaluating military personnel with blast-related mild traumatic brain injuries, researchers have found that early symptoms of post-traumatic stress, such as anxiety, emotional numbness, flashbacks and irritability, are the strongest predictors of later disability.READ MORE
Researchers at Aalto University and University of Turku have revealed how obesity is associated with altered opioid neurotransmission in the brain. New research reveals how obesity is associated with altered functioning of brain’s opioid system, which is intimately involved in generating pleasurable sensations.READ MORE
Carnegie Mellon University neuroscientists have identified a new pathway by which several brain areas communicate within the brain's striatum.READ MORE
Doctors write millions of prescriptions a year for drugs to calm the behavior of people with Alzheimer's disease and other types of dementia. But non-drug approaches actually work better, and carry far fewer risks, experts conclude in a new report.READ MORE
New research published in the American Journal of Psychiatry indicates a strong link between subthreshold manic episodes and likelihood of developing bipolar disorder in children of parents with bipolar disorder.READ MORE
People sniff their hands twice as much after a handshake, according to a new study Why do people shake hands? A new Weizmann Institute study suggests one of the reasons for this ancient custom may be to check out each other's odors.READ MORE
