Intense exercise could help to gain control over cravings for unhealthy foods

In a study that offers hope for human dieters, rats on a 30-day diet who exercised intensely resisted cues for favored, high-fat food pellets.

Abnormalities in astrocytes may play a key role in causing autism spectrum disorder symptoms

Abnormalities in a type of brain cell called astrocytes may play a pivotal role in causing some behavioral symptoms of autism spectrum disorders, according to a preclinical study by Weill Cornell Medicine investigators.

Researchers identify brain areas that control the ability to perform complex, sequential movements

In a novel set of experiments with mice trained to do a sequence of movements and "change course" at the spur of the moment, Johns Hopkins scientists report they have identified areas of the animals' brains that interact to control the ability to perform complex, sequential movements, as well as to help the mice rebound when their movements are interrupted without warning.

People who accumulate cardiovascular risk factors quickly have higher risk of developing dementia

Cardiovascular disease risk factors, like high blood pressure, diabetes, obesity and smoking, are believed to play key roles in the likelihood of developing cognitive decline, dementia, and Alzheimer's disease.

Novel methods for inferring the movement of brain cells during fetal development

The making of a human brain remains a mostly mysterious process that races from an embryonic neural tube to more than 100 billion interconnected neurons in the brain of a newborn. To achieve this marvel of biological engineering, the developing fetal brain must grow, on average, at a rate of roughly 250,000 nerve cells per minute throughout the course of a pregnancy.

Single-cell genome sequencing provides a new way to think about Alzheimer’s disease

Alzheimer's disease is marked by a loss of functional neurons in the brain. But what causes this loss? Through single-cell genome sequencing, researchers at Boston Children's Hospital, Brigham and Women's Hospital, and the Broad Institute show that people with Alzheimer's have an abundance of newly acquired mutations in their neurons - more than people of the same age without Alzheimer's, and enough to disable genes important to brain function.

Scientists demonstrate a new mechanism by which amino acids curb appetite

Proteins can suppress appetite, so a protein-rich diet can help people lose weight. That's just one of the reasons why this kind of diet has become increasingly popular in recent years.

New evidence from a zebrafish model may help understand how epileptic seizures originate

New evidence from a zebrafish model of epilepsy may help resolve a debate into how seizures originate, according to Weill Cornell Medicine and NewYork-Presbyterian investigators.

Einstein Aging Study secures $32 million NIH grant to help address the rising tide of Alzheimer's disease

To help address the rising tide of Alzheimer's disease nationwide, researchers at Albert Einstein College of Medicine in collaboration with faculty at Pennsylvania State University and other institutions, have received a five-year, $32 million grant from the National Institutes of Health to support the ongoing Einstein Aging Study, which focuses on both normal aging and the special challenges of Alzheimer's disease, and other dementias. EAS was established at Einstein in 1980 and has been continuously funded by the NIH.

Levels of little-studied enzyme found to decline with age and more dramatically with Alzheimer’s

A little-studied enzyme has been found in high levels in healthy neurons, levels that scientists say decline with age and more dramatically with Alzheimer's, making adjusting the enzyme's level a potential treatment for both.

Better understanding of hydrocephalus could lead to improved treatments

Hydrocephalus, or "water on the brain," occurs when the cerebral ventricles - four interconnected cavities of the brain that are filled with cerebrospinal fluid - become enlarged, but its cause is unknown in many cases.

Researchers use computationally simple neuron model to simulate complex neuronal responses

The study shows the Izhikevich neuron model allows the simulation of both periodic and quasi-periodic responses in neurons at lower computational cost.

The brain uses an alarm system to suppress unwanted memories

Forget what you saw: a brain region detects when you are about to think of an unwanted memory and alerts other regions to suppress it, according to research recently published in JNeurosci.

Inhibiting key signaling pathway in immune cells may slow down Alzheimer's disease

Inhibiting an important signaling pathway in brain-resident immune cells may calm brain inflammation and thereby slow the disease process in Alzheimer's and some other neurodegenerative diseases, suggests a study by Weill Cornell Medicine investigators.

Exercise maintains insulin and body mass index levels to help protect brain volume

Studies have shown that exercise helps protect brain cells. A new study looking at the mechanisms involved in this relationship suggests that the role exercise plays in maintaining insulin and body mass index levels may help protect brain volume and thus help stave off dementia.

Social connections predict the brain structure of primates

What's the link between social life and brain structure? Researchers from the University of Pennsylvania, the Stem Cell and Brain Research Institute at Inserm, and elsewhere are now one step closer to understanding this connection for rhesus macaques.

Prenatal exposure to maternal social disadvantage may affect infant brain volumes at birth

Poverty and crime can have devastating effects on a child's health. But a new study from researchers at Washington University School of Medicine in St. Louis suggests that some environmental factors influence the structure and function of young brains even before babies make their entrances into the world.

Machine-learning approach predicts development of conduct disorder with high accuracy

Conduct disorder (CD) is a common yet complex psychiatric disorder featuring aggressive and destructive behavior.

Bilingualism can slow down the course of age-related changes in the brain

Medical advances are causing a gradual increase in average life expectancy. However, this comes at a price, as the number of cases of dementia and other neurodegenerative diseases grows with age. Researchers from HSE University (Russia) and Northumbria University (UK) have found that bilingualism can slow down and mitigate the course of age-related changes in the human brain.

New Russian-language protocol for fMRI enables preoperative mapping of language areas

Neurolinguists from HSE University, in collaboration with radiologists from the Pirogov National Medical and Surgical Centre, developed a Russian-language protocol for functional magnetic resonance imaging (fMRI) that makes it possible to map individual language areas before neurosurgical operations.
