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

Use of transplanted induced pluripotent stem cells could lead to new treatments for HD

Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington's disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Researchers develop new technique that converts stem cells into brain cells

A new technique that converts stem cells into brain cells has been developed by researchers at Lund University. The method is simpler, quicker and safer than previous research has shown and opens the doors to a shorter route to clinical cell transplants.

Brain can rewire even at an advanced age

"This study overturns decades-old beliefs that most of the brain is hard-wired before a critical period that ends when one is a young adult," said MPFI neuroscientist Marcel Oberlaender, PhD, first author on the paper.

UCSF scientists aim to use embryonic stem cells for treatment of neuropathic pain

Chronic pain, by definition, is difficult to manage, but a new study by UCSF scientists shows how a cell therapy might one day be used not only to quell some common types of persistent and difficult-to-treat pain, but also to cure the conditions that give rise to them.

Changes in sensory experience can cause massive rewiring of the brain

Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition.

Human olfactory bulb differs from that of other mammals

Research from Karolinska Institutet in Sweden shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals.
