Brain Stimulation Eases Parkinson’s Disease, Boosting Dopamine

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…

New Brain Map Could Improve AI Algorithms For Machine Vision

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…

Map Of The Brain Can Tell What You Are Reading

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 disease

Genetic Instability In Brain Cells, Triggers Huntington’s Disease

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…

Multiple sclerosis

Vegetable-Rich Diet Lowers Fatigue In Multiple Sclerosis Patients

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…

Non-Invasive Electrical Stimulation Alters Blood Flow In Brain Tumors

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…

Brain-Computer Interfaces

Tricky Interfaces: Brain-Computer Interfaces Are Still A Long Way Off

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…

Post-traumatic stress disorder

Brain Stimulation For Post-Traumatic Stress Disorder Patients

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,…

Amyloid

Amyloid Is A Less Accurate Marker, Progression Of Alzheimer’s

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 Brain’s Decline Before People Realize

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…
