Insights into the physics of brain activity

The same rules of physics that govern molecules as they condense from gas to liquid, or freeze from liquid to solid, also apply to the activity patterns of neurons in the human brain.

Two-way cell talk provides clues about neuromuscular disease

It's a scientific given that neurons tell other cells what to do, but new evidence suggests that, like with any good relationship, these target cells also have much to contribute, scientists say.

Lab on a chip mimics chemical complexities of the brain

Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool - a lab on a chip - designed to mimic the chemical complexities of the brain.

Scientists reprogram human skin cells into embryonic stem cells

UCLA stem cell scientists have reprogrammed human skin cells into cells with the same unlimited properties as embryonic stem cells without using embryos or eggs.

Robotic rats to aid in rescue missions

A new initiative, bringing together nine research groups from seven countries, including teams of robotics and brain researchers from Europe, the USA and Israel, has recently been set up with the aim of imitating nature.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).

Prion infection of neurons increases the free cholesterol content in cell membranes

A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

RNA-associated introns guide nerve-cell channel production

Researchers at the University of Pennsylvania School of Medicine have discovered that introns, or junk DNA to some, associated with RNA are an important molecular guide to making nerve-cell electrical channels.

Poor recognition of 'self' found in high functioning people with autism

Contrary to popular notions, people at the high end of the autism spectrum disorder continuum suffer most from an inability to model "self" rather than impaired ability to respond to others, said Baylor College of Medicine researchers in a report that appear in the journal Neuron.

Predisposition for obesity might be wired into the brain

A predisposition for obesity might be wired into the brain from the start, suggests a new study of rats in the February issue of Cell Metabolism, a publication of Cell Press.

New devices to boost nematode research on neurons and drugs

A pair of new thin, transparent devices, constructed with soft lithography, should boost research in which nematodes are studied to explore brain-behavior connections and to screen new pharmaceuticals for potential treatment of parasitic infections in humans, report 10 scientists at three institutions.

Microscopic imaging technique reveals rapid formation of Alzheimer's-associated plaques

The amyloid plaques found in the brains of Alzheimer's disease patients may form much more rapidly than previously expected.

Brain disturbances in chronic pain

People with unrelenting pain don't only suffer from the non-stop sensation of throbbing pain.

Brain circuitry that drives drug-seeking compulsion identified

In experiments with rats, researchers have identified the change in brain circuitry that drives development of a compulsion to seek drugs, even when that compulsion is self-destructive.

Brain study suggests way to measure, treat autism

Researchers have pinpointed subtle deficits in the brains of people with autism spectrum disorder (ASD) that they say could aid more precise diagnoses and perhaps improve treatment of ASD.

Structure of important neurotransmitter regulator solved

Researchers from Virginia Tech and the Brookhaven National Laboratory have solved the structure of an enzyme that is critical in the regulation of the neurotransmitter system in the human brain.

Targeting astrocytes slows progression of Lou Gehrig's disease

In what the researchers say could be promising news in the quest to find a therapy to slow the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, scientists at the University of California, San Diego (UCSD) School of Medicine have shown that targeting neuronal support cells called astrocytes sharply slows disease progression in mice.

New Parkinson's disease research points to serotonin

For most people with Parkinson's disease, the only relief from the tremors, rigidity and impaired movement associated with the progressive loss of their motor skills is a drug called L-DOPA. But as the disease progresses, L-DOPA can cause prominent side effects that counteract its effectiveness.

Neurogenesis plays an important role in the acquisition and storage of spatial memory

Boosted by physical and mental exercise, neural stem cells continue to sprout new neurons throughout life, but the exact function of these newcomers has been the topic of much debate.
