New ways of how biological clock's neurons use electrical activity to keep behavioral rhythms in order

Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also point to fresh directions for exploring sleep disorders and related afflictions.

Common RNA pathway links frontotemporal lobar dementia with ALS

Two proteins previously found to contribute to ALS, also known as Lou Gehrig's disease, have divergent roles. But a new study, led by researchers at the Department of Cellular and Molecular Medicine at the University of California, San Diego School of Medicine, shows that a common pathway links them.

Rapamycin can alleviate frontotemporal lobar degeneration

A southern Taiwan-based National Cheng Kung University (NCKU) research team has discovered that rapamycin, a drug as a autophagy activator is a possible treatment to alleviating frontotemporal lobar degeneration (FTLD), one of the mainly causes of dementia, and so far no medication can be used.

Molecular link between spinal muscular atrophy and amyotrophic lateral sclerosis

Researchers of motor neuron diseases have long had a hunch that two fatal diseases, amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA), might somehow be linked. A new study confirms that this link exists.

Efavirenz drug may play a key role in brain damage

The way the body metabolizes a commonly prescribed anti-retroviral drug that is used long term by patients infected with HIV may contribute to cognitive impairment by damaging nerve cells, a new Johns Hopkins research suggests.

Fly neurons may uncover secrets of Alzheimer's disease

Although they're a common nuisance in the home, fruit flies have made great contributions to research in genetics and developmental biology. Now a Tel Aviv University researcher is again turning to this everyday pest to answer crucial questions about how neurons function at a cellular level - which may uncover the secrets of neurological disorders such as Alzheimer's disease.

Biologists reveal one way that biological clocks control neuronal activity

Biologists at New York University have uncovered one way that biological clocks control neuronal activity - a discovery that sheds new light on sleep-wake cycles and offers potential new directions for research into therapies to address sleep disorders and jetlag.

Orexin-A hormone also affects emergence after anesthesia

A neuropeptide hormone called orexin-A—which plays an important role in regulating the normal sleep-wake cycle—also affects emergence (waking up) after anesthesia, reports an experimental study in the October issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Lasers manipulate neurons in worms' brains

In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's brain, instruct it to turn in any direction they choose, and even to implant false sensory information, fooling the animal into thinking food was nearby.

New mouse models can help scientists study SECISBP2 syndrome

New mouse models can help scientists study a rare disease, called SECISBP2 syndrome, that causes abnormal thyroid hormone metabolism, delayed bone maturation, as well as other abnormal characteristics that vary by individual, according to new data presented at the 82nd Annual Meeting of the American Thyroid Association (ATA) in Québec City, Québec, Canada.

Molecular disruptions in granule cells cause epileptic seizures in mice

Scientists have discovered the first direct evidence that a biological mechanism long suspected in epilepsy is capable of triggering brain seizures – opening the door for studies to seek improved treatments or even preventative therapies.

Adults with autism have unreliable neural sensory responses to visual, auditory and touch

Autistic adults have unreliable neural sensory responses to visual, auditory, and touch stimuli, according to research published in the journal Neuron. This poor response reliability, the study's authors conclude, appears to be a fundamental neural characteristic of autism.

Diet, lack of AgRP-neurons can lead to obesity and diabetes

The absence of a specific type of neuron in the brain can lead to obesity and diabetes in mice report researchers in The EMBO Journal. The outcome, however, depends on the type of diet that the animals are fed.

UCSF-led research team targets physiological factors that lead to asthma attack

A new study that identifies ways to reduce the factors that lead to an asthma attack gives hope to asthma sufferers. A UCSF researcher and his colleagues believe they have found a way to help asthma sufferers by impeding the two most significant biological responses that lead to an asthma attack.

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.

Brandeis University biology professor receives NIH Director's New Innovator award

Chances are you didn't spend much time this morning getting your shoes on or thinking about which route you would take to work. But for people suffering with debilitating diseases such as ALS (Lou Gehrig's disease) or Alzheimer's, such simple functions -- and even activities like breathing and eating -- can be a struggle.

Researchers regenerate axons at spinal cord injury site

In a study at the University of California, San Diego and VA San Diego Healthcare, researchers were able to regenerate "an astonishing degree" of axonal growth at the site of severe spinal cord injury in rats.

Ageing in neurons follows same rules as in senescing fibroblasts

The ageing process has its roots deep within the cells and molecules that make up our bodies. Experts have previously identified the molecular pathway that react to cell damage and stems the cell's ability to divide, known as cell senescence.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Neuronal inhibition plays key role in memory formation

Stefan Remy and colleagues at the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn have illuminated how this system works. "The system acts like a filter, only letting the most important impulses pass," explains Remy. "This produces the targeted neuronal patterns that are indispensible for long-term memory storage."
