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.

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

Lyme disease emerging in Canada

Lyme disease is emerging in Canada, and is expected to increase with climate change, but effective, enhanced surveillance and clinician awareness will be key to minimizing the impact of the disease, write researchers in a review in CMAJ (Canadian Medical Association Journal).

Insomniacs need increased brain activation to maintain normal daily function

According to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, patients suffering from chronic primary insomnia (PIs) have higher levels of brain activation compared to normal sleepers during a working memory test.

Research links primary insomnia to specific neurochemical abnormality

A research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, is the first demonstration of a specific neurochemical abnormality in adults with primary insomnia (PI), providing greater insight to the limited understanding of the condition's pathology.

Research shows how cells tell time

In a new study appearing online this week in the Proceedings of the National Academy of Sciences, Dr. Liu and his co-workers have found that this mold, which uses a protein called FRQ as the main gear of its clock, marks time by a sequence of changes in the protein's chemical structure.

Rhes protein responsible for brain cell damage in Huntington disease

Johns Hopkins brain scientists have figured out why a faulty protein accumulates in cells everywhere in the bodies of people with Huntington's disease (HD), but only kills cells in the part of the brain that controls movement, causing negligible damage to tissues elsewhere.

Research investigates the treatment of traumatic brain and head injury

The National Institute for Health Research Health Technology Assessment (NIHR HTA) programme is expanding the evidence base surrounding the treatment of traumatic brain and head injury (TBI) by commissioning four new research projects. If left untreated many patients with head injury will rapidly develop complications which may lead to death or permanent disability. More than 100,000 people in the UK have long-term effects caused by such injuries. Prompt medical treatment may prevent the worsening of symptoms and lead to a better outcome.

Prophylactic cranial irradiation prevents early lung cancer metastases to the brain

A national Radiation Therapy Oncology Group (RTOG) study led by a Medical College of Wisconsin Cancer Center physician at Froedtert Hospital in Milwaukee has found that a course of radiation therapy to the brain after treatment for locally advanced non-small cell lung cancer reduced the risk of metastases to the brain within the first year after treatment. The study was presented at the American Society of Clinical Oncology annual meeting in Orlando, June 1.

Needle biopsies safe in 'eloquent' areas of brain

After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain.

Baucus: Obama open to taxing health benefits to pay for health reform

On the same day President Obama expressed the urgent need for health care reform, he also met with two dozen Senate Democrats and suggested that he is open to considering taxing employer-provided health benefits to pay for health care reform, The Washington Post reports.

Research questions standard protocol for treating traumatic brain injury

Traumatic brain injury - not heart disease, stroke or cancer - is the number one cause of death and disability in people under 45. Each year, some 1.5 million Americans, including soldiers, athletes, the elderly and children, sustain head injuries, and nearly half of them will be hospitalized and treated in an emergency room or intensive care unit.

Research sheds new light on how the brain processes what the eye sees

Researchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding "perceptual stability" and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from awareness.
