The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Study: CCSVI may result from multiple sclerosis progression

A just released study on the relationship between multiple sclerosis and chronic cerebral venous insufficiency, a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause.

New research finds older adults consume more phytonutrients than youths

Although only one in 10 American adults eats enough fruits and vegetables, new research being presented at the Experimental Biology meeting this week in Washington, D.C., finds older adults are consuming higher levels of carotenoids, flavonoids and other phytonutrients found in fruits and vegetables that are thought to support healthy aging.

New insights into dynamics of amyloid fibrils

A research study, published yesterday in the Journal of the American Chemical Society, demonstrates that the aggregation of amyloid-beta proteins into amyloid fibrils characteristic of Alzheimer's disease is not irreversible, as previously thought.

Cytonet initiates clinical trial using liver cell infusion to treat urea cycle disorders in children

International biotechnology firm Cytonet recently launched the first ever clinical trial in the United States using an investigational liver cell infusion to treat urea cycle disorders (UCD) in children. The first patient in the Phase II trial, which will seek to enroll 20 patients in 12 medical centers, is a child with citrullinemia, which is a hereditary UCD. He received six liver cell infusions on six consecutive days at Yale School of Medicine in New Haven, Conn.

Investigational Alzheimer's compounds may treat neuropathies

Drugs already in development to treat Alzheimer's disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis.

Astrocytes regulate circadian system that controls normal sleep patterns

The circadian system that controls normal sleep patterns is regulated by a group of glial brain cells called astrocytes, according to a study published online on April 14th in Current Biology, a Cell Press publication. Neuroscientists from Tufts University School of Medicine found that disruption of astrocyte function in fruit flies ( Drosophila) led to altered daily rhythms, an indication that these star-shaped glial cells contribute to the control of circadian behavior.

Mandatory single embryo transfers for IVF may decrease risk and cost

The number of couples struggling with infertility is on the rise, and these couples often use assisted reproductive technologies, like in vitro fertilization (IVF), to get pregnant. Although IVF can be successful, it can also increase the risk of multiple pregnancies, which are often caused by transferring more than one embryo. Twins and triplets are likely to be born prematurely, and, as a result, many have medical complications.

Study: 30% of patients with TBI more likely to suffer from depression

Vanderbilt researchers conducting an extensive analysis of studies on traumatic brain injury, report today that 30 percent of TBI patients, or approximately 360,000 patients each year, will also suffer from depression after their injury.

Treatment of vascular risk factors may lower risk of Alzheimer's disease

Treating high blood pressure, high cholesterol, diabetes and other vascular risk factors may help lower the risk of Alzheimer's disease in people who already show signs of declining thinking skills or memory problems. The research is published in the April 13, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Insight into Cervical Spondylotic Myelopathy

Researchers at the Krembil Neuroscience Centre, Toronto Western Hospital have identified a cell receptor, which is responsible for cell death in the spinal cord in a condition called Cervical Spondylotic Myelopathy.

Stimulation of brain nerves accelerates learning

In a breakthrough that may aid treatment of learning impairments, strokes, tinnitus and chronic pain, UT Dallas researchers have found that brain nerve stimulation accelerates learning in laboratory tests.

Serotonin can help promote human intimacy and romantic feelings

The judgments we make about the intimacy of other couples' relationships appear to be influenced by the brain chemical serotonin, reports a new study published in Biological Psychiatry.

Mortality rates increase 800% when epilepsy and autism occur together

A comprehensive investigation of brain tissue donated to the Autism Speaks Autism Tissue Program (ATP), a postmortem brain tissue donation program, determined that one-third of the brain donors with autism also had epilepsy, and co-morbidity data from the California State Department of Developmental Services revealed a higher than expected rate of mortality in individuals with both autism and epilepsy than for individuals with autism alone.

AAN, PDF honor Boston researcher with Clinician Scientist Development Award

A clinician scientist at Massachusetts General Hospital in Boston is receiving $240,000 to further his research into how stem cells may be used to treat Parkinson's disease through the American Academy of Neurology Foundation and the Parkinson's Disease Foundation Clinician Scientist Development Award in Parkinson's Disease Research.

New MRI device can make deep brain stimulation effective for patients

A new MRI device that guides surgeons as they implant electrodes into the brains of people with Parkinson's disease and other neurological disorders could change the way this surgery, called deep brain stimulation, is performed at medical centers across the country, according to a group of doctors at University of California, San Francisco.

NIST's new reference can aid in Huntington's disease diagnosis

A new Standard Reference Material from the National Institute of Standards and Technology will help clinical genetics labs accurately diagnose Huntington's disease, an inherited degenerative brain disorder that usually begins between ages 35 and 50 and progressively leads to physical impairment, dementia and death.

Scientists link increase of calcium influx in brain neurons to long-term memory

Using advanced imaging technology, scientists from the Florida campus of The Scripps Research Institute have identified a change in chemical influx into a specific set of neurons in the common fruit fly that is fundamental to long-term memory.

Scientists identify filter neurons that can reduce 'brain clutter'

Until now, it has been assumed that people with diseases like ADHD, Tourette syndrome, obsessive compulsive disorder and schizophrenia - all of whom characteristically report symptoms of "brain clutter" - may suffer from anomalies in the brain's prefrontal cortex.

Study: Simple illusion can reduce arthritic pain

A serendipitous discovery by academics at The University of Nottingham has shown that a simple illusion can significantly reduce — and in some cases even temporarily eradicate — arthritic pain in the hand.

Brain damage starts decade earlier in Alzheimer’s patients

A new study published in the journal Neurology has shown that the brains of people diagnosed with Alzheimer's disease start shrinking up to a decade before symptoms appear. Researchers from Rush University Medical Center in Chicago and Massachusetts General Hospital in Boston did brain imaging tests on older adults with no signs of memory loss.
