Methamphetamine addiction mechanism discovered

Researchers have identified, for the first time, long-term changes in the brain circuitry of methamphetamine-addicted mice that can explain why the craving of addiction is so stubborn and long-lived.

How protein sludge accumulates in Alzheimer's

Researchers have identified a key mechanism by which the protein sludge that kills brain cells accumulates in Alzheimer's disease (AD).

Diabetes drug may hold potential as treatment for epilepsy, using same mechanism as ketogenic diet

Two years ago, University of Wisconsin-Madison scientists reported they had suppressed epileptic seizures in rats by giving them a glycolytic-inhibitor, inhibiting the brain's ability to turn sugar into excess energy and blocking the expression of seizure-related genes.

Parkinson transplants survive at least 16 years

Transplanted cells can survive in the brain for over one and half decade. However, some of the transplanted cells developed Parkinson-like features which is very surprising.

Identification of dopamine 'mother cells' could lead to future Parkinson's treatments

'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia.

Leaky blood vessels open up nerve cells to toxic assault In Lou Gehrig's disease

Leaky blood vessels that lose their ability to protect the spinal cord from toxins may play a role in the development of amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig's disease, according to research published in the April issue of Nature Neuroscience.

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection

As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease.

Fetal cells transplanted into the brain to treat Parkinson's may not function long term

Neurons grafted into the brain of a patient with Parkinson's disease fourteen years ago have developed Lewy body pathology, the defining pathology for the disease, according to research by Jeffrey H. Kordower, PhD, and associates and published in the April 6 issue of Nature Medicine.

New potential approach to treat spinal muscular atrophy

In the neuromuscular disease called spinal muscular atrophy, or SMA, a protein deficiency caused by a single gene mutation leads to serious damage in growing nerve cells and the muscles they control.

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.
