Lamin nucleoskeleton disordered in Alzheimer's

Brain cell death in Alzheimer's disease is linked to disruption of a skeleton that surrounds the nucleus of the cells, a researcher in the School of Medicine at The University of Texas Health Science Center at San Antonio said.

CMU joins $12 million research project to reverse-engineer the brain's secret algorithms

Carnegie Mellon University is embarking on a five-year, $12 million research effort to reverse-engineer the brain, seeking to unlock the secrets of neural circuitry and the brain's learning methods. Researchers will use these insights to make computers think more like humans.

UCI researchers identify potential strategies to prevent cognitive decline

As brain cells age they lose the fibers that receive neural impulses, a change that may underlie cognitive decline. Researchers at the University of California, Irvine recently found a way to reverse this process in rats. The study was published February 3 in The Journal of Neuroscience. Researchers caution that more studies are needed, but the findings shed light on the mechanisms of cognitive decline and identify potential strategies to stem it.

Study reveals fetal origin for social and repetitive behavior deficits

Fetal development has been known to play an important role in social interaction, a fundamental behavior found in nearly all organisms, and later adult social behaviors. Autism, a highly heritable neurodevelopment disorder that causes difficulties with social interactions, has been postulated to be caused by neuron overgrowth in the prenatal period, although the precise timing and cause of this overgrowth has been unknown.

New analysis method may help categorise stroke patients with language problem

Brain researcher Karsten Specht has found a new method of analysis to distinguish between stroke patients with language problem. The result may be individualised treatment for each patient.

Understanding crucial role of 'healthy' brain in preventing memory failures linked to Alzheimer's disease

The mechanisms underlying the stability and plasticity of neural circuits in the hippocampus, the part of the brain responsible for spatial memory and the memory of everyday facts and events, has been a major focus of study in the field of neuroscience. Understanding precisely how a "healthy" brain stores and processes information is crucial to preventing and reversing the memory failures associated with Alzheimer's disease (AD), the most common form of late-life dementia.

New study lays foundation for future gene replacement therapies to treat ALS patients

Scientists have demonstrated for the first time that it is possible to specifically modify gene expression in diseased upper motor neurons, brain cells that break down in ALS.

Research offers novel insights into root causes of schizophrenia

Schizophrenia is a mysterious and devastating disorder that afflicts one percent of the adult population worldwide. Its symptoms — hallucinations, emotional withdrawal, and cognitive impairment — are chronic and typically emerge just as individuals are entering adulthood. Today's medications treat just one of these symptoms (psychosis); treatments for the underlying disease and its many other symptoms have been hard to develop, because no one really understands what causes the disorder.

HIV protein alters activity of networked neurons

Nearly half of HIV infected patients suffer from impaired neurocognitive function. The HIV protein transactivator of transcription (Tat) is an important contributor to HIV neuropathogenesis because it is a potent neurotoxin that continues to be produced despite treatment with antiretroviral therapy.

Graphene-based electrodes could be safely implanted in the brain

Researchers have successfully demonstrated how it is possible to interface graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson's disease.

Remicade co-developer funds new microscopy facility on Scripps Florida campus

The co-developer of Remicade, one of the three top-selling drugs in the world, has donated more than $500,000 to fund what will be known as the Iris and Junming Le Foundation Super-Resolution Microscopy Facility on the Florida campus of The Scripps Research Institute.

Researchers discover previously unknown mechanism that regulates neurogenesis

Bassem Hassan's team at VIB/KU Leuven has discovered a previously unknown mechanism that is highly conserved between species and which regulates neurogenesis through precise temporal control of the activity of a family of proteins essential for brain development: the proneural proteins.

Brain's natural plasticity could compensate for inner ear damage

Researchers from Massachusetts Eye and Ear/Harvard Medical School have described, for the first time, the adult brain's ability to compensate for a near-complete loss of auditory nerve fibers that link the ear to the brain. The findings, published in the current issue of Neuron, suggest that the brain's natural plasticity can compensate for inner ear damage to bring sound detection abilities back within normal limits; however, it does not recover speech intelligibility.

New treatment could stop progression of ALS

Researchers at Oregon State University announced today that they have essentially stopped the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, for nearly two years in one type of mouse model used to study the disease - allowing the mice to approach their normal lifespan.

New computational techniques could help researchers pinpoint anatomical source of seizures

For the third of all epilepsy patients who don't respond to medication, an alternative is to locate the small cluster of neurons that act as the seed of a seizure's aberrant electrical activity and surgically remove it. Unfortunately, such surgeries often fail to bring any relief. The ability to reliably pinpoint the anatomical source of seizures, different for each patient, remains elusive.

Study could open door for new treatment targets to help Parkinson's disease patients walk more easily

Two secrets of one of the brain's most enigmatic regions have finally been revealed. In a pair of new studies, scientists from the Gladstone Institutes have discovered a specific neural circuit that controls walking, and they found that input to this circuit is disrupted in Parkinson's disease.

CNIO team uses network theory to build and study first epigenetic communication network

One of the big questions for which there is still no clear answer in biology is how, based on the four universal letters that make up DNA, it is possible to generate such different organisms as a fly or a human, or the different organs and tissues they comprise. In recent years, researchers have discovered that the system is much more complicated than was originally thought.

Researchers create new neuronal connections for the first time

That very fine hair-line object that you see being pulled across the screen is actually a neuron being made. A research team led by McGill University and the Montreal Neurological Institute has managed to create new functional connections between neurons for the first time. Apart from the fact that these artificial neurons grow over 60 times faster than neurons naturally do, they are indistinguishable from ones that grow naturally in our bodies.

Scientists pin down molecular process linked to schizophrenia origin

For the first time, researchers have managed to home in on a molecular process in the brain that contributes to the development of schizophrenia.

New findings offer roadmap for development of novel therapies to target common brain disorders

Scientists have pinpointed the cells that are likely to trigger common brain disorders, including Alzheimer's disease, Multiple Sclerosis and intellectual disabilities.
