In a new study of seven people with Parkinson’s disease, Johns Hopkins Medicine researchers; report evidence that deep brain stimulation using electrical impulses jumpstarts the nerve cells that produce the chemical messenger dopamine; to reduce tremors and muscle rigidity that are the hallmark of Parkinson’s disease, and increases feelings of well-being. “While deep brain stimulation…
Despite years of research, the brain still contains broad areas of unchartered territory. A team of scientists, led by neuroscientists from Cold Spring Harbor Laboratory and University of Sydney; recently found new evidence revising the traditional view of the primate brain’s visual system organization using data from marmosets. This remapping of the brain could serve…
Changes in blood pressure in those as young as 36; are linked to markers of poorer brain health in later life, finds UCL-led research involving participants of Britain’s oldest running birth cohort study. The findings from the Insight 46 study are published in The Lancet Neurology. Insight 46 is a neuroscience sub-study; of the MRC…
Too busy or lazy to read Melville’s Moby Dick or Tolstoy’s Anna Karenina? That’s OK. Whether you read the classics, or listen to them instead, the same cognitive; and emotional parts of the brain are likely to be stimulated. And now, there is a map to prove it. Neuroscientists at the University of California, Berkeley,…
Huntington’s caused by a mutation in a gene that makes a protein called Huntington. Huntington’s disease trigger by genetic instability of a particular DNA sequence in brain cells, according to a new study of the lethal neurodegenerative disorder. If confirmed, the study could lead to new methods to prevent disease onset. It could also result…
Higher levels of blood high-density lipoprotein (HDL) or good cholesterol may improve fatigue in multiple sclerosis patients; according to a new University at Buffalo-led study. The pilot study, which investigated the effects of fat levels in blood on fatigue caused by multiple sclerosis; found that lowering total cholesterol also reduced exhaustion. However, the results, published…
In a first-of-its kind study, neurologists at Beth Israel Deaconess Medical Center (BIDMC); tested the use of non-invasive electrical stimulation as a novel therapeutic approach to brain tumors. In an experiment published in Science Advances; the scientists led by Emiliano Santarnecchi, demonstrated that applying low-intensity electrical stimulation to the brains of patients with tumors; resulted…
We live in a violent society, with the U.S. rate of deaths from gun violence four times higher than; the rates in war-torn countries like Syria and Yemen. The violence in our society can be exacerbated by stress; and these incidents can cause a new wave of fear to spread across the country. From a…
It will still be a long time before brain-computer interfaces are able to read thoughts. And many limitations need to be consider, according to Roger Gassert. Brain-computer interfaces (BCIs) allow people with severe physical or speech disabilities to interact; and communicate with their surroundings using their thoughts interpreted by a computer. Elon Musk’s Neuralink recently…
For 8-million adults who suffer from post-traumatic stress disorder in any given year; medication and cognitive therapy have been the treatment protocol. Now, University of Houston assistant professor of electrical engineering Rose T. Faghih is reporting in Frontiers in Neuroscience that a closed-loop brain stimulator, based on sweat response; developed not only for PTSD patients,…
While the presence of beta-amyloid plaques in the brain may be a hallmark of Alzheimer’s disease; giving patients an amyloid PET scan is not an effective method for measuring their cognitive function; according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania and Thomas Jefferson University. The…
Some older adults without noticeable cognitive problems have a harder time than younger people; in separating irrelevant information from what they need to know at a given time; and a new Johns Hopkins University study could explain why. The findings offer an initial snapshot of what happens in the brain as young and old people…
