Rodents may hold the key to long and active lifespan

Compared to the average three year life span of a common rat, the 10 to 30 year life of the naked mole rat, a subterranean rodent native to East Africa, is impressive. And compared to the human body, the body of this rodent shows little decline due to aging, maintaining high activity, bone health, reproductive capacity, and cognitive ability throughout its lifetime. Now a collaborative of researchers in Israel and the United States is working to uncover the secret to the small mammal's long - and active - lifespan.

Neuralstem commences dosing in NSI-189 Phase Ib trial for major depressive disorder

Neuralstem, Inc. announced that the first patients were dosed in Phase Ib of its ongoing trial to test the safety of NSI-189 in the treatment of major depressive disorder (MDD).

Study reveals function of dorsal anterior cingulate cortex in the brain

Every day the human brain is presented with tasks ranging from the trivial to the complex. How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness. Now a study from Massachusetts General Hospital (MGH) researchers finds that a structure deep within the brain, believed to play an important role in regulating conscious control of goal-directed behavior, helps to optimize behavioral responses by predicting how difficult upcoming tasks will be.

Novel small-molecule-inhibiting drug stops spread of breast cancer cells

Scientists have developed a small-molecule-inhibiting drug that in early laboratory cell tests stopped breast cancer cells from spreading and also promoted the growth of early nerve cells called neurites.

New understanding of how motor neurons die in spinal muscular atrophy patients

Cedars-Sinai's Regenerative Medicine Institute has pioneered research on how motor-neuron cell-death occurs in patients with spinal muscular atrophy, offering an important clue in identifying potential medicines to treat this leading genetic cause of death in infants and toddlers.

Distinct brain regions organize objects based on their physical size

The human brain can recognize thousands of different objects, but neuroscientists have long grappled with how the brain organizes object representation; in other words, how the brain perceives and identifies different objects. Now researchers at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and the MIT Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size, with a specific region of the brain reserved for recognizing large objects and another reserved for small objects.

Researchers can silence mutated gene responsible for Huntington's with single drug treatment

With a single drug treatment, researchers at the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine can silence the mutated gene responsible for Huntington's disease, slowing and partially reversing progression of the fatal neurodegenerative disorder in animal models.

Researchers discover protein required to regrow injured peripheral nerves

A protein required to regrow injured peripheral nerves has been identified by researchers at Washington University School of Medicine in St. Louis.

Researchers develop double viral vector transfection technique

The collaborative research team led by Professor Tadashi ISA, Project Assistant Professor Masaharu KINOSHITA from The National Institute for Physiological Sciences, The National Institutes of Natural Sciences and Fukushima Medical University and Kyoto University, developed "the double viral vector transfection technique" which can deliver genes to a specific neural circuit by combining two new kinds of gene transfer vectors.

Research into alcohol's effect on juvenile rats

Research into alcohol's effect on juvenile rats shows they have an ability to build up a physical, but not cognitive, tolerance over the short term - a finding that could have implications for adolescent humans, according to Baylor University psychologists.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Mutation responsible for rare, hereditary motor neuron disease disrupts vital links

Studying how nerve cells send and receive messages, Johns Hopkins scientists have discovered new ways that genetic mutations can disrupt functions in neurons and lead to neurodegenerative disease, including amyotrophic lateral sclerosis (ALS).

dSarm/Sarm1 gene promotes axon destruction after injury

Degeneration of the axon and synapse, the slender projection through which neurons transmit electrical impulses to neighboring cells, is a hallmark of some of the most crippling neurodegenerative and brain diseases such as amyotrophic lateral sclerosis (ALS), Huntington's disease and peripheral neuropathy.

Paper spotlights unique developmental strategy undertaken by all mammals

Ask the average person the street how the brain develops, and they'll likely tell you that the brain's wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, and new branches are built as they learn and grow. A new study conducted in a Harvard lab, however, suggests that just the opposite is true.

Study describes how seizures in people with AS could be linked to brain cell activity imbalance

New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder.

Artificial noses could allow quick disease screening and ultimately transform diagnostics

Artificial noses have, until now, been used to detect diseases such as urinary tract infection, Helicobacter pylori, tuberculosis, ear, nose and throat conditions and even lung cancer. They have also been clinically tested for use in continuous monitoring of different disease stages.

Transcranial magnetic stimulation enhances visual abilities in healthy adults

Using transcranial magnetic stimulation (TMS), an international team led by researchers from the Centre de Recherche de l'Institut du Cerveau et de la Moelle Epinière (CNRS / Inserm / UPMC) has succeeded in enhancing the visual abilities of a group of healthy subjects.

Scientists propose new theory of the brain activity behind arm movements

Unlike their visual cousins, the neurons that control movement are not a predictable bunch. Scientists working to decode how such neurons convey information to muscles have been stymied when trying to establish a one-to-one relationship between a neuron's behavior and external factors such as muscle activity or movement velocity.

Electronic nose and optoacoustics improve diagnosis of prostate cancer

Chances of survival of prostate cancer depend strongly on the stage at which the disease is diagnosed. Now scientists have developed new methods relying on an electronic nose and optoacoustics to improve the diagnosis techniques and avoid fatal treatment delays
