New way to stimulate transplanted human stem cell-derived neurons into a rodent hippocampus

Researchers and patients look forward to the day when stem cells might be used to replace dying brain cells in Alzheimer's disease and other neurodegenerative conditions. Scientists are currently able to make neurons and other brain cells from stem cells, but getting these neurons to properly function when transplanted to the host has proven to be more difficult.

Study shows how Parkinson's spreads and leads to nerve cell death

Understanding how any disease progresses is one of the first and most important steps towards finding treatments to stop it. This has been the case for such brain-degenerating conditions as Alzheimer's disease. Now, after several years of incremental study, researchers at the Perelman School of Medicine, University of Pennsylvania have been able to piece together important steps in how Parkinson's disease (PD) spreads from cell to cell and leads to nerve cell death.

S100A4 protein triggers repair processes in the brain after injury

Researchers at the University of Copenhagen have found that a protein, known for causing cancer cells to spread around the body, is also one of the molecules that trigger repair processes in the brain.

CLR01 effectively inhibits synaptotoxicity in mice with Alzheimer's

Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson's disease from binding together and killing the brain's neurons.

New pathway appears to play a major role in information processing in the brain

Scientists at The Scripps Research Institute (TSRI) have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

D737 compound restores motor function and longevity in fruit flies with Alzheimer's

An efficient, high-volume technique for testing potential drug treatments for Alzheimer's disease uncovered an organic compound that restored motor function and longevity to fruit flies with the disease, according to new research that could help put the search for an effective Alzheimer's drug on a faster track.

Researchers make groundbreaking discovery into optimization of light sources to human vision

Vision researchers at Barrow Neurological Institute have made a groundbreaking discovery into the optimization of light sources to human vision. By tuning lighting devices to work more efficiently with the human brain the researchers believe billions of dollars in energy costs could be saved.

Braking mechanism in olfactory neurons helps generate amazing diversity of sensors in the nose

The human nose has millions of olfactory neurons grouped into hundreds of different neuron types. Each of these neuron types expresses only one odorant receptor, and all neurons expressing the same odorant receptor plug into one region in the brain, an organization that allows for specific odors to be sensed.

Research shows reduced plasticity in brains of preterm teens

New research at the University of Adelaide has demonstrated that teenagers born prematurely may suffer brain development problems that directly affect their memory and learning abilities.

Medulloblastomas that arise from different cell types might require personalized treatments

Cancers arise when a normal cell acquires a mutation in a gene that regulates cellular growth or survival. But the particular cell this mutation happens in-the cell of origin-can have an enormous impact on the behavior of the tumor, and on the strategies used to treat it.

Brevetoxin-2 stimulates nerve cell growth and plasticity in cultured mouse neurons

A new study using brevetoxin-2, a compound produced naturally by marine algae, stimulated nerve cell growth and plasticity in cultured mouse neurons. This research advances a potentially new pharmacological treatment to aid recovery of brain function following a stroke or other traumatic brain injury.

Study reveals how interneurons navigate during cerebral cortex development

As the brain develops, each neuron must find its way to precisely the right spot to weave the intricate network of links the brain needs to function. Like the wiring in a computer, a few misplaced connections can throw off functioning for an entire segment of the brain.

Dopamine improves long-term memory

The feel-good hormone dopamine improves long-term memory. This is the finding of a team lead by Emrah D-zel, neuroscientist at the German Center for Neurodegenerative Diseases and the University of Magdeburg.

Communications down in anesthetized brain

Two studies indicate that inhaled anesthetics disrupt communication between distant cortical areas before directly activating sleep-inducing neuronal circuitry.

Early clues regarding progression of Alzheimer's disease found in brain's metabolism

When it comes to Alzheimer's disease, scientists usually - and understandably - look to the brain as their first center of attention. Now researchers at Tel Aviv University say that early clues regarding the progression of the disease can be found in the brain's metabolism.

Researchers simulate activity of cultured neural networks

After a short period of growth, cultured networks of neurons regularly exhibit major activity in the absence of external stimulation. These "bursts" are entirely related to growth. At this stage, they have little to do with learning behaviour, as the network is still too young to sustain a process of memory formation. This has now for the first time been simulated for networks ranging in size from 10,000 to 50,000 neurons. The simulations provide insight into the role of the growth process in initial activity.

Nanofiber technique to build new nerves from stem cells

Every week in his clinic at the University of Michigan, neurologist Joseph Corey, M.D., Ph.D., treats patients whose nerves are dying or shrinking due to disease or injury.

Brain switches into special mode when pushed to make rapid decisions

Why do our brains make more mistakes when we act quickly? A new study demonstrates how the brain follows Ben Franklin's famous dictum, "Take time for all things: great haste makes great waste."

Alpha-herpesvirus axon-to-cell spread involves limited virion transmission

New research suggests that just one or two individual herpes virus particles attack a skin cell in the first stage of an outbreak, resulting in a bottleneck in which the infection may be vulnerable to medical treatment.

Degeneration of serotonergic neurons linked to spasticity in ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with an occurrence rate in France similar to multiple sclerosis (two to three new cases per year for every 100,000 residents). It has a specific affect on neurons responsible for motor control, in particular motor neurones and central motor neurones. The former, located in the spinal cord, are directly linked to muscles and are used for muscle contraction and stretching.
