Alzheimer's vaccine clears amyloid plaques but has little effect on learning and memory impairment

A promising vaccine being tested for Alzheimer's disease does what it is designed to do -- clear beta-amyloid plaques from the brain -- but it does not seem to help restore lost learning and memory abilities, according to a University of California, Irvine study.

Stem cell breakthrough offers diabetes hope

Scientists have discovered a new technique for turning embryonic stem cells into insulin-producing pancreatic tissue in what could prove a significant breakthrough in the quest to find new treatments for diabetes.

Alcohol alters prefrontal cortex activity through ion channel disruption

The prefrontal cortex (PFC) region of the brain is involved in decision making. New rodent findings show that PFC neuron N-methyl-D-aspartic acid (NMDA) receptors are especially sensitive to concentrations of alcohol achieved during drinking.

New nano-engineered gel inhibits for spinal cord injury

A spinal cord injury often leads to permanent paralysis and loss of sensation below the site of the injury because the damaged nerve fibers can't regenerate.

Fluorodeoxyglucose positron emission tomography to help determine whether cognitive impairment will lead to Alzheimer's

With nearly 10 million baby boomers at risk for developing Alzheimer's disease, researchers are taking a closer look at a condition known as mild cognitive impairment.

Mouse calls help search for emotion-controlling genes

Scientists have long known that emotions and other personality traits and disorders run together in families.

Do humans hear better than animals?

It is known that various species of land and water-based living creatures are capable of hearing some lower and higher frequencies than humans are capable of detecting.

Exercise delays onset of Huntington’s in mouse model

The simple act of running in an exercise wheel delays the onset of some symptoms of Huntington's disease in a mouse model of the fatal human disorder according to research published in the open-access journal BMC Neuroscience.

Discovery of novel gene responsible for Lou Gehrig's disease

A team of Canadian and French researchers has identified a novel gene responsible for a significant fraction of ALS (sporadic amyotrophic lateral sclerosis) cases.

Discovery of new type of retinal cell

Harvard University researchers have discovered a new type of retinal cell that plays an exclusive and unusual role in mice: detecting upward motion.

Researchers examine human embryonic stem cell genome

Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility.

Neurons hard wired to tell left from right

It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour.

Umbilical cord blood cell therapy may reduce signs and symptoms of Alzheimer's disease

Targeted immune suppression using human umbilical cord blood cells may improve the pathology associated with Alzheimer's disease, a new study in a mouse model of this currently untreatable neurodegenerative condition reports.

New brain cells implicated in machinery of cannabinoid signaling

The researchers said their findings could aid in development of treatments for cannabinoid drug abuse. Also, because so-called "endocannabinoids" produced by brain cells are involved in the neural machinery of pain perception and learning and memory, the findings could help in understanding those processes, said the researchers.

Insulin-like growth factor found to have new role in development of brain's smell center

A human hormone known to stimulate the growth of cells throughout the body has a new role - helping to set up the proper nerve connections in the odor center of the brain, according to University of California, Berkeley, scientists.

The brain can sense the calories in food, independent of taste

Their finding that the brain's reward system is switched on by this “sixth sense” machinery could have implications for understanding the causes of obesity. For example, the findings suggest why high-fructose corn syrup, widely used as a sweetener in foods, might contribute to obesity.
