New Genetically Engineered Proteins Allow Scientists to Watch Nerve Cells Spark in Real Time
Thursday, Apr 4, 2013
Neurons send electric sparks from one end of the cell to another. The action potential, a distinctive change in voltage, is a hallmark of electric signaling in neurons. Usually researchers directly monitor these signals with cumbersome electrodes or toxic voltage-sensitive dyes, or indirectly with calcium detectors. For decades, they tried developing voltage-sensitive fluorescent proteins, called fluorogenetic voltage sensors, as a less-invasive alternative. In addition, these detectors could be used in specific types of neurons, including ones that are inaccessible with traditional methods. Previous attempts did not produce proteins sensitive enough to watch action potentials and subtle voltage changes in real time.
Learning may Spindle Tiny Parts of the Sleeping Brain
Thursday, Apr 4, 2013
How does the brain remember? A growing body of evidence suggests that sleep is important, especially a sleep stage called nonrapid eye movement (NREM) sleep. During NREM, the brain undergoes unique waves of electrical activity called sleep spindles. Previous studies suggested that spindles represent learning activity. Currently scientists are debating whether spindles occur synchronously, throughout the entire brain, or locally in the areas involved with something new.

Targeting Brain’s ‘Go’ Pathway Might Help Relieve Parkinson’s Symptoms
Friday, Sep 24, 2010
Parkinson’s disease affects the brain’s motor control circuitry, causing rigidity, slowed movement and poor balance. In a study published in Nature,* researchers have teased apart this circuitry, confirming that it contains two distinct pathways – a “go” pathway that tells the body to move and a “stop” pathway that suppresses movement. Tipping the balance in favor of the go pathway might help treat patients.
Spinal Cord Injury, Spasms, and Serotonin
Monday, Sep 20, 2010
When people think of spinal cord injury, they tend to think of paralysis. But a spinal cord injury can also cause debilitating muscle spasms. Although the drug baclofen can control these spasms, many patients cannot tolerate its side effects. A new study sheds light on how a spinal cord injury leads to spasms, and on the promise of more precisely targeted drugs with fewer side effects.

Drugs and Stress Management Together Best Manage Chronic Tension Headache: Clinical Trial Proves Benefit of Combined Therapies
Only a fraction of stroke patients each year are getting to the hospital in time to receive a treatment that makes the difference between disability and full recovery. Thousands more people could benefit from the treatment—a drug called tissue plasminogen activator (t-PA)—but do not, often because they do not know the symptoms of stroke or do not get to the hospital within the drug's 3-hour window of effectiveness. The National Institute of Neurological Disorders and Stroke (NINDS) is launching a national public education campaign, 'Know Stroke: Know the Signs. Act in Time,' to help people overcome these barriers and to get medical help in time.

Turning Blood into Brain: New Studies Suggest Bone Marrow Stem Cells Can Develop into Neurons in Living Animals
Thursday, Nov 30, 2000
For years, researchers studying stem cells have been intrigued by the possibility that these cells might be used to treat brain diseases. Recent studies have suggested that neural stem cells transplanted into the brain can migrate throughout the brain and develop into other types of cells. Now, two new studies show that bone marrow cells transplanted into mice can migrate into the brain and develop into cells that appear to be neurons. The studies suggest that bone marrow may be a readily available source of neural cells with potential for treating such neurological disorders as Parkinson's disease and traumatic brain injury.

Parkinson's Disease Is More Than a Brain Disorder
Monday, Sep 4, 2000
Scientists Pinpoint Possible Cause for Debilitating Sleep Disorder Narcolepsy
For many years, researchers have known that the movement problems associated with Parkinson's disease result from a loss of neurons that produce a nerve-signaling chemical called dopamine in one part of the brain. A new study suggests that Parkinson's disease (PD) also affects nerve endings that produce a related chemical, norepinephrine, in the heart. The finding improves understanding about how Parkinson's disease develops and may lead to a way of predicting the disorder and possibly even preventing it. Fact Sheet

NINDS Hosts First Parkinson's Disease Implementation Committee Meeting to Establish Priorities for Parkinson's Research
Scientists believe they may have identified the cause of the debilitating sleep disorder narcolepsy in humans. A new study shows a dramatic reduction — up to 95 percent — in the number of neurons containing a substance called hypocretins in the brains of people with narcolepsy compared to control brains. Hypocretin peptides are neurotransmitters that play an important role in regulating sleep and appetite. The researchers hypothesize that the pronounced loss of these neurons could be caused either by a neurodegenerative process or an autoimmune response. Fact Sheet

Widely Used Therapy May Not Be Effective in Treatment of Acute Stroke
Tuesday, Apr 21, 1998
General use of anticlotting drugs, like low-molecular-weight (LMW) heparinoids, immediately after a stroke has little effect in producing a good outcome or in preventing a second stroke in most patients, according to the results of a large clinical trial published in the April 22, 1998, issue of The Journal of the American Medical Association.
Most People Can't Identify Stroke Symptoms
Tuesday, Apr 21, 1998
A new study shows that most people can't identify even one symptom of stroke -- the number one cause of disability and the third leading cause of death in this country. And the people most likely to suffer a stroke -- those over 75 years old -- are the least likely to know the symptoms of stroke and whether they're at risk for having a stroke.
Peptides Implicated in Body's Response to Pain
Wednesday, Mar 25, 1998
Pain is an extremely disabling condition leading to an annual cost of $65 billion lost in work productivity and 4 billion work days. It also accounts for 40 million visits per year to physicians for "new" pain and $3 billion in sales each year of over-the-counter analgesics. Scientists studying animal models with support from the National Institutes of Health have found that a chemical, called neurokinin A, may be responsible for the body's response to moderate-to-intense pain. This finding, reported in the March 26, 1998, issue of Nature, may eventually lead to new treatments for pain.

A Hereditary Ataxia Caused by Huntington's-Type "Genetic Stutter"
Wednesday, Jun 30, 1993
Scientists have discovered that another nervous system degenerative disorder, spinocerebellar ataxia type 1 (SCA1), has the same type of gene mutation occurring in Huntington's and Kennedy's diseases. In the disease, a normal three-base sequence in the genetic code — cytosine, adenine and guanine, or CAG — is abnormally repeated, according to Drs. Huda Y. Zoghbi, who led one team at the Baylor College of Medicine in Houston, Texas, and Harry T. Orr, who headed the other team at the University of Minnesota in Minneapolis. The same CAG repeat was reported earlier this year in Huntington's disease and in 1991 in the very rare Kennedy's disease, also called X-linked spinobulbar muscular atrophy.

These findings, reported in the current issue of Proceedings of the National Academy of Sciences,* may eventually lead to improved diagnosis and treatment for this inherited disorder and yield new insight into the metabolism of cholesterol inside the body's cells.
DATATOP Study Confirms Deprenyl's Efficacy in Fighting the Progression of Parkinson's Disease
Wednesday, Jan 20, 1993
Scientists announced today in the January 21 New England Journal of Medicine the results of a broad, long-term study on the effects of deprenyl and tocopherol (a form of vitamin E) on the progression of early Parkinson's disease. The investigators, who comprise a group known as the Parkinson's Study Group, confirmed that deprenyl is effective in slowing the early progression of Parkinson's disease and delaying the need for initiation of therapy with the drug levodopa. The latest results of the study showed, however, that the beneficial effects of deprenyl were not as lasting in fighting Parkinson's disease as the investigators had anticipated when evaluating the preliminary results in 1989. The clinical trials also showed no evidence that tocopherol was useful in Parkinson's disease.
Brain Damage Disrupts Emotions and Mood
Tuesday, May 5, 1992
Feeling tense and anxious? Unfettered and carefree? It may be all in your head or — rather — your cerebral hemispheres. According to scientists at the National Institute of Neurological Disorders and Stroke (NINDS), new research suggests that the brain's hemispheres generate our emotional outlook. Scientists also say their findings, announced today at the annual meeting of the American Academy of Neurology in San Diego, show that brain damage can change judgment of emotion and distort normal mood.
