Dragonfly capable of higher-level thought processes when hunting its prey

In a discovery that may prove important for cognitive science, our understanding of nature and applications for robot vision, researchers at the University of Adelaide have found evidence that the dragonfly is capable of higher-level thought processes when hunting its prey.

Two recent experimental treatments improve visual function in mouse models of retinitis pigmentosa

Two recent experimental treatments - one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy - have been shown to produce long-term improvement in visual function in mouse models of retinitis pigmentosa (RP), according to the Columbia University Medical Center (CUMC) scientists who led the studies. At present, there is no cure for RP, the most common form of inherited blindness.

FUS RNA binding ability essential for development of Amyotrophic Lateral Sclerosis

Research led by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, has found that the ability of a protein made by a gene called FUS to bind to RNA is essential to the development of Amyotrophic Lateral Sclerosis (ALS). This discovery identifies a possible therapeutic target for the fatal neurological disease.

Scientists uncover TDP-43 protein as possible target for treatment of ALS, FTD

Neuroscientists at Georgetown University Medical Center say they have new evidence that challenges scientific dogma involving two fatal neurodegenerative diseases - amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD) - and, in the process, have uncovered a possible therapeutic target as a novel strategy to treat both disorders.

GI bacteria exert some control over their hosts' appetites: Review

Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, France, and coauthors propose yet another role for GI bacteria: that they exert some control over their hosts' appetites.

AAV-based gene therapy cocktail may help extend lives of children with Canavan disease

Results of a clinical trial that began in 2001 show that a gene therapy cocktail conveyed into the brain by a molecular special delivery vehicle may help extend the lives of children with Canavan disease, a rare and fatal neurodegenerative disorder.

Lou Gehrig's disease may be treatable using neural stem cells

Promising new research provides evidence that ALS, amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, may be treatable using neural stem cells.

Harvard scientists shed new light on olfactory feedback mechanism

More than a century after it was first identified, Harvard scientists are shedding new light on a little-understood neural feedback mechanism that may play a key role in how the olfactory system works in the brain.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Research provides broader understanding of processes that lead to Alzheimer's disease

Alzheimer's disease is the most common form of dementia, affecting over 35 million people worldwide. It is generally assumed that the clumping of beta-amyloid (Aβ) protein causes neuronal loss in patients.

TUBB5 gene responsible for microcephaly: IMP study

Neurobiologists at the Research institute of Molecular Pathology (IMP) in Vienna have discovered one of the key genes required to make a brain. Mutations in this gene, called TUBB5, cause neurodevelopmental disease in children.

LED light instantly triggers or reverses depression-like behavior in rodents

A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced pleasure-seeking - they avoided other animals and lost their sweet tooth.

Bumetanide could treat children with severe autism or Asperger's syndrome

Although this therapy is not curative, it nevertheless reduced the autistic disorders' severity in three-quarters of the children. The researchers have filed a request for authorisation to perform a multi-centre European clinical trial in order to determine more precisely the population concerned by this therapy.

AZD6765 briefly improves treatment-resistant patients' depression symptoms in minutes

A drug that works through the same brain mechanism as the fast-acting antidepressant ketamine briefly improved treatment-resistant patients' depression symptoms in minutes, with minimal untoward side effects, in a clinical trial conducted by the National Institutes of Health. The experimental agent, called AZD6765, acts through the brain's glutamate chemical messenger system.

Skin vibrations convey information to the brain much the same way as auditory system

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall's surface and make a better guess for where the switch is.

Study identifies KNDy neurons as a likely control switch of hot flushes

Hot flushes affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.

Carbon nanotubes can help regulate chloride levels in nerve cells that contribute to neural injuries

A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury.

Lack of TDP-43 protein can lead to frontotemporal dementia/ALS

Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

Scientists uncover molecular basis of gentle touch

Stroke the soft body of a newborn fruit fly larva ever-so-gently with a freshly plucked eyelash, and it will respond to the tickle by altering its movement-an observation that has helped scientists at the University of California, San Francisco (UCSF) uncover the molecular basis of gentle touch, one of the most fundamental but least well understood of our senses.

FoxP3 gene expression identifies ALS disease progression in 80% of patients

The debilitating symptoms of amyotrophic lateral sclerosis, or ALS, appear to be increased by a lack of inflammation-reducing T cells, report scientists from the Methodist Neurological Institute in an upcoming print issue of The EMBO Molecular Medicine Journal.
