Vitamin B reduces risk of developing Alzheimer's disease

Adults who eat the daily recommended allowance of folates - B-vitamin nutrients found in oranges, legumes, leafy green vegetables and folic acid supplements - significantly reduce their risk of developing Alzheimer's disease, according to results from a long-term National Institute on Aging study of diet and brain aging.

There are subtle effects of hearing loss on memory and cognitive function in older adults

In a new study, Brandeis University researchers conclude that older adults with mild-to-moderate hearing loss may expend so much cognitive energy on hearing accurately that their ability to remember spoken language suffers as a result.

Key step in the production of beta-amyloid

Researchers at UT Southwestern Medical Center have defined a key step in the production of beta-amyloid, a short protein that is thought to be responsible for the development of Alzheimer's disease. Understanding this step may aid in the discovery of drugs that could help block the disease from developing.

Endorphin system may hold the key to understanding and treating bulimia nervosa

The role of the brain's opioid receptor system - or endorphin system - may hold the key to understanding and treating bulimia nervosa, according to research reported in the Society of Nuclear Medicine's August issue of the Journal of Nuclear Medicine.

Researchers look at how we understand visual images

The figure is famous: a deceptively simple line drawing that at first glance resembles a vase and, at the next, a pair of human faces in profile. When you look at this figure, your brain must rapidly decide what the various lines denote. Are they the outlines of the vase or the borders of two faces? How does your brain decide?

New theory as to why some people die during sleep

According to scientists the reason why some people stop breathing fatally in their sleep, is because a cumulative loss of cells in the area of the brain that controls breathing triggers a condition called central sleep apnoea.

Breastfeeding lowers mothers stress

Moms, want to lower stress? Try breastfeeding. New research from the McGill-affiliated Douglas Hospital Research Centre in Montreal shows mothers who breastfeed respond less to stressful situations than those who bottle-feed their children. These findings suggest these mothers may be better able to care for their children.

Nighttime dying linked to sleep apnea from brain cell loss

Aim to grow old and die peacefully in your sleep? Be careful what you wish for. A new UCLA study suggests that some people die in their sleep because they stop breathing due to a cumulative loss of cells in the brain's breathing command-post. The online edition of Nature Neuroscience reports the findings.

Brain may interpret the information it receives from sensory neurons using a code more complicated than scientists previously thought

...according to new research from the National Autonomous University of Mexico and Cold Spring Harbor Laboratory. By studying how monkeys perceive a vibrating object when it touches the skin, scientists found that changes in an animal's attention over time influence how a sensory signal is interpreted.

Nerve-insulating substance called myelin can lead to functional improvements in animals with spinal cord injury

Combining partially differentiated stem cells with gene therapy can promote the growth of new "insulation" around nerve fibers in the damaged spinal cords of rats, a new study shows.

Multiple rare mutations within a single gene may increase risk for autism

While debate still rages over the 'cause' of autism, mounting evidence suggests that genetic factors play a major role in the disease.

U.S. scientists find 3 molecules that could help fight Alzheimer's

A team of scientists at the Neuroscience Research Institute at the University of California, Santa Barbara, say they have identified three molecules that appear to stop a key culprit behind Alzheimer's disease.

Hearing protein TRPA1 also involved with pain perception

The same protein that “translates” sound into nerve signals to the brain and enables individuals to hear is also required for pain perception, researchers from Northwestern University Feinberg School of Medicine have found.

Potential use of NH neurotransmitters as novel source for psychiatric drugs

Physiologists and medical researchers have long recognized the important endocrine roles played by the pituitary hormones oxytocin (OT) and vasopressin (VP) on peripheral systems in lactation, uterine contraction and urine concentration.

Spontaneous contractions suppressed in late-term rat pregnancy

A long-time aim of obstetrical research has been to find agents that could delay or diminish pre-term labor because even today pre-term birth is a leading cause of infant mortality and morbidity.

Researchers have identified a protein that is crucially involved in how our memories are stored and processed

University of Queensland researchers have identified a protein that is crucially involved in how our memories are stored and processed, paving the way for new strategies to treat conditions certain mental disorders.

Discovery of a chemical messenger called neuropeptide Y (NPY) in taste bud cells

The tongue's ability to differentiate between sweet and bitter tastes may reside in the same taste bud cells, a new study reports.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Important role of early experience in shaping neuronal development

Scientists at New York University School of Medicine reveal the important role of early experience in shaping neuronal development and brain plasticity in a new study published in the July 14 issue of the journal Nature.

Researchers gain better understanding of how nerves need to be reconnected after spinal cord injury

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message?
