Sleep protects the brain against Alzheimer’s by washing it

Researchers have found that when in deep sleep, the brain waves within can start off a cleaning system within the brain that can protect it against Alzheimer’s and other neurodegenerative brain diseases. The study titled, “Coupled electrophysiological, hemodynamic, and cerebrospinal fluid oscillations in human sleep,” was published this week in the latest issue of the journal Science.

UVA research sheds light on why infant seizures have lifelong effects

A doctor at University of Virginia Children's is using an elegant new approach to mapping brain activity to shed light on what happens during seizures in newborns that can lead to behavioral issues and learning disabilities much later.

Gulf War Illness and chronic fatigue syndrome are two very distinct diseases of the brain

Gulf War Illness (GWI) and chronic fatigue syndrome (CFS) share symptoms of disabling fatigue, pain, systemic hyperalgesia (tenderness), negative emotion, sleep and cognitive dysfunction that are made worse after mild exertion (postexertional malaise).

How dementia spreads: new study says it’s through neural networks

Scientists have found out a way to forecast the spread of brain atrophy, using prior research that shows how brain networks connect with each other to form a continuously linked pathway.

Dementia spreads via synaptic connections between brain networks

In a new study, UC San Francisco scientists used maps of brain connections to predict how brain atrophy would spread in individual patients with frontotemporal dementia, adding to growing evidence that the loss of brain cells associated with dementia spreads via the synaptic connections between established brain networks.

Brain scans may be promising tool to identify suicide risk in people with mood disorders

Researchers at the University of Utah Health and University of Illinois at Chicago have identified brain circuitry differences that might be associated with suicidal behavior in individuals with mood disorders.

Lack of sleep increases junk food cravings via nose-brain interactions

After a night without sleep, the hand reaches out almost automatically for anything rich, sweet and unhealthy – a change in food choice which could increase the body weight if practiced consistently over a significant period of time

Intensive physical training can harm brain capacity, shows study

In top athletes, excess physical activity can be harmful, as cases of 'overtraining syndrome' suggest. It is associated with major fatigue and reduced athletic performances.

Brain changes may help track people most likely to develop dementia

Even before dementia diagnosis, people with mild cognitive impairment may have different changes in the brain depending on what type of dementia they have, according to a study published in the September 11, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Brain maps show activity related to meaning and not mode of learning

A new brain mapping experiment shows that whether you read or listen to a book, the same parts of the brain are stimulated to help you understand and respond to the meaning of the words (or the ‘semantics’).

Individual differences in pleasure are due to genetic variation, research suggests

Differences in how our brains respond when we're anticipating a financial reward are due, in part, to genetic differences, according to research with identical and fraternal twins published in Psychological Science, a journal of the Association for Psychological Science.

Using mathematical model to trace brain transitions

Unique in its application of a mathematical model to understand how the brain transitions from consciousness to unconscious behavior, a study at The City College of New York's Benjamin Levich Institute for Physico-Chemical Hydrodynamics may have just advanced neuroscience appreciably.

Researchers study blood flow bump that happens when the neurons get activated

When a group of our neurons get activated by thinking hard about a math problem or the vibrant colors of an exotic flower, within a single second blood flow to those brain cells increases a bit.

New imaging method to identify patients with ischemic heart disease

An international team led by scientists from Lawson Health Research Institute and Cedars-Sinai Medical Center are the first to show that Magnetic Resonance Imaging can be used to measure how the heart uses oxygen for both healthy patients and those with heart disease.

Seeing disfigured faces evokes negative behavioral and brain reactions

People with attractive faces are often seen as more trustworthy, socially competent, better adjusted, and more capable in school and work.

Music helps to develop the neural networks of premature infants

In Switzerland, as in most industrialized countries, nearly 1% of children are born "very prematurely", i.e. before the 32nd week of pregnancy, which represents about 800 children yearly.

Researchers use brain scans to provide better understanding of unconscious bias

Unconscious bias has become a hot topic recently, with high profile incidents reported around the world. Researchers at Aalto University are exploring the causes of these biases in our neural wiring, and are developing techniques using MRI scanners that let us see the brain making assumptions in real time.
