Key regulator of lens development also controls mechanosensory neuron development

A gene known to control lens development in mice and humans is also crucial for the development of neurons responsible for mechanosensory function, as neurobiologists of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have now discovered.

Brain tissue created from human skin cells

British scientists have successfully generated brain tissue from human skin. The team has for the first time generated a crucial type of brain cells in the laboratory by reprogramming skin cells. They say it could speed up the hunt for new treatments for conditions such as Alzheimer's disease, epilepsy and stroke.

Researchers discover a startling feature of early brain development

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

Deep brain stimulation helps improve memory and cognitive skills in epilepsy patients

Researchers have found that deep brain stimulation by sending in electric shocks to a part of the brain that plays a key role in memory improved people's ability to learn. This could raise hope for patients of Alzheimer’s.

Tai chi could benefit Parkinson’s disease patients

A new study found that a six-month program of Tai Chi exercises helped people with various stages of Parkinson's disease improve stability, their ability to walk and reduced the frequency of falls.

Cancer drug bexarotene effective in mouse model of Alzheimer’s

Case Western Reserve University School of Medicine neuroscientist Gary Landreth and colleagues reported Thursday that the drug - bexarotene quickly cleared away beta-amyloid plaque, believed to cause the cognitive deficits of Alzheimer's disease, from the brains of genetically engineered mice.

Single fibronectin injection can prevent chronic pain development after SCI

Chronic neuropathic pain following a spinal cord injury is common and very difficult to treat, but a new therapeutic strategy requiring a one-time injection into the spinal column has potential to improve patient outcomes.

Parkinson’s disease gene - parkin explored: Study

Researchers at the University at Buffalo have discovered how mutations in the parkin gene cause Parkinson's disease, which afflicts at least 500,000 Americans and for which there is no cure. The results are published in the current issue of Nature Communications.

Deep-brain stimulation of entorhinal cortex can strengthen memory

Ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory.

Scientists discover how individual MST neurons function

When you are about to collide into something and manage to swerve away just in the nick of time, what exactly is happening in your brain? A new study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows how the brain processes visual information to figure out when something is moving towards you or when you are about to head into a collision.

Low-dose MNC hUCB therapy effective in ALS-modeled mice

Repeated, low-dose injections of mononuclear cells derived from human umbilical cord blood have been found effective in protecting motor neuron cells, delaying disease progression and increasing lifespan for mice modeling amyotrophic lateral sclerosis, or ALS, also referred to as Lou Gehrig's disease, report University of South Florida researchers and colleagues from Saneron CCEL Therapeutics, Inc., and the Ribeirao Preto School of Medicine at the University of Sao Paulo, Brazil.

Two different research groups make similar advances in AD study

Two different research groups have independently made the same important discoveries on how Alzheimer's disease spreads in the brain, according to a February 2 New York Times story. The groups' findings have the potential to give us a much more sophisticated understanding of what goes wrong in Alzheimer's disease and, more importantly, what can be done to prevent or repair damage in the brain.

Study offers evidence that toxic forms of Alzheimer's protein spread in the brain

Tau tangles are one half of the twin hallmark pathologies of Alzheimer's disease—the half that is most closely tied to the death of neurons. A study in the February 1 PLoS One offers evidence that the toxic forms of tau that cause these tangles spread throughout the brain by moving from one neuron to the next in a pattern that tracks anatomical synaptic connections of the earliest-hit nerve cells in the brain.

Scientists discover extremely long-lived proteins in aging rats

One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.

Researchers tease out toxic role of tau oligomers in Alzheimer's

One of the most distinctive signs of the development of Alzheimer's disease is a change in the behavior of a protein that neuroscientists call tau. In normal brains, tau is present in individual units essential to neuron health. In the cells of Alzheimer's brains, by contrast, tau proteins aggregate into twisted structures known as "neurofibrillary tangles."

Skin cells converted to brain cells without intermediate stem cell stage

Researchers from California have successfully converted mouse skin cells into cells which develop into the main components of the brain. The experiment, reported in Proceedings of the National Academy of Sciences, is notable because it skipped the middle “stem cell” stage in the process.

Abnormal tau protein propagates along linked brain circuits

For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study by Columbia University Medical Center (CUMC) researchers strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer's, propagates along linked brain circuits, "jumping" from neuron to neuron.

Healthy lung tissue transplantation shows promise for patients with pulmonary diseases

For patients suffering from severe pulmonary diseases including emphysema, lung cancer or fibrosis, transplantation of healthy lung tissue may offer the best chance for survival. The surgical procedure, however, faces two primary challenges: an acute shortage of donor lungs and rejection of transplanted tissue by the recipient's immune system.

Valence, arousal, and sex differences play a major role in brain activity

A woman's memory of an experience is less likely to be accurate than a man's if it was unpleasant and emotionally provocative, according to research undertaken by University of Montreal researchers at Louis-H Lafontaine Hospital.

Breakthroughs in Alzheimer’s disease research

Researchers are closer to understanding Alzheimer’s disease using a new stem cell technique. They have successfully replicated Alzheimer’s disease neurons with stem cells for the first time.
