Nutrition has Benefits for Brain Network Organization

The study of 99 healthy older adults, recruited through Carle Foundation Hospital in Urbana, compared patterns of fatty acid nutrients found in blood samples, functional MRI data that measured the efficiency of brain networks, and results of a general intelligence test. The study was published in the journal NeuroImage. "Our goal is

Mind Wandering is Common During Driving

Are you always attentive when driving? How about on the monotonous commute home after a long day's work? It can be difficult to keep our attention sharp while driving, especially on routes that we drive daily, or when we are tired after work. However, driver inattention is a major factor

Zika Virus Kills Brain Cancer Stem Cells

The findings suggest that the lethal power of the virus -- known for infecting and killing cells in the brains of fetuses, causing babies to be born with tiny, misshapen heads -- could be directed at malignant cells in the brain. Doing so potentially could improve people's chances against a

New Source for Brain’s Development Discovered

The research, which appears in the journal Science, discovered that glia, a collection of non-neuronal cells that had long been regarded as passive support cells, in fact are vital to nerve-cell development in the brain. "The results lead us to revise the often neuro-centric view of brain development to now appreciate the

The Pancreas Provides a Potential Drug Candidate for Brain Disease

In normal development, oligodendrocyte precursor cells (OPCs) differentiate into oligodendrocytes, which are required for myelination. OPCs will proliferate around the lesions of demyelination after injury and contribute to spontaneous remyelination, but the molecular mechanism of OPCs proliferation is not fully clarified. Osaka University Associate Professor Rieko Muramatsu focused on the

Fragile X Syndrome Early Detection Important

This picture of the basic nature of Fragile X has been reinforced by a series of studies reported in a paper titled "Fragile X Mental Retardation Protein Requirements in Activity Dependent Critical Period Neural Circuit Refinement" published Aug. 7 in the journal Current Biology. The research was conducted by a team of

Physical Exercise Prevents Dementia

In order to further advance current state of knowledge on the positive influence of physical activity on the brain, gerontologists and sports physicians at Goethe University Frankfurt have examined the effects of regular exercise on brain metabolism and memory of 60 participants aged between 65 and 85 in a randomised

Neuroticism May Postpone Death for Some

"Our findings are important because they suggest that being high in neuroticism may sometimes have a protective effect, perhaps by making people more vigilant about their health," says lead researcher Catharine R. Gale of the University of Edinburgh and University of Southampton. By definition, people with high levels of neuroticism are

Network of Neurons Crucial for Vocal Learning Identified

A new study from the Peter O'Donnell Jr. Brain Institute demonstrates in songbirds the necessity of this neural circuit to learn vocalizations at a young age, a finding that expands the scientific understanding of some contributing factors in speech disorders in humans. "Speech and language learning depend on our ability to
