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.

Leptin hormone also regulates airway diameter

A new study led by Columbia University Medical Center (CUMC) researchers has found that leptin, a hormone that plays a key role in energy metabolism, fertility, and bone mass, also regulates airway diameter.

Abnormal fixation may contribute to deficits in face perception in AMD patients

Abnormalities of eye movement and fixation may contribute to difficulty in perceiving and recognizing faces among older adults with age-related macular degeneration (AMD), suggests a study "Abnormal Fixation in Individuals with AMD when Viewing an Image of a Face" appearing in the January issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Overall cancer death rates continue to decline in the U.S.: Report

The Annual Report to the Nation on the Status of Cancer, 1975-2009, shows that overall cancer death rates continued to decline in the United States among both men and women, among all major racial and ethnic groups, and for all of the most common cancer sites, including lung, colon and rectum, female breast, and prostate.

Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

Dopamine-related drug exposure, Parkinson's increase risk of impulse control problems

Parkinson's disease itself does not increase the risk of impulse control problems such as compulsive gambling and shopping that have been seen in people taking certain drugs for Parkinson's disease, according to new research published in the January 8, 2013, print issue of Neurology, the medical journal of the American Academy of Neurology.

Beta blockers can reduce risk of Alzheimer's, other types of dementia

People taking the blood pressure drugs called beta blockers may be less likely to have changes in the brain that can be signs of Alzheimer's disease and other types of dementia, according to a study released today that will be presented at the American Academy of Neurology's 65th Annual Meeting in San Diego, March 16 to 23, 2013.

Insect research yields insights for muscle control and nerve disorders in mammals

Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins' mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad implications for human disease research.

Researchers deploy sensitive brain-testing methods on injured high school athletes

The ability to focus and switch tasks readily amid distractions was compromised for up to two months following brain concussions suffered by high school athletes, according to a study at the University of Oregon.

Dementia diagnosis: an interview with Dr Andrew Blackwell, Chief Scientific Officer, Cambridge Cognition

Dementia is a huge public health problem, affecting about 800,000 people in the UK and 36 million people around the world.

EHR implementation with technical support can improve patient care in small physician practices: Study

The relationship between a physician practice's adoption of electronic health records (EHR) and quality improvements in patient care remains unclear.

Complications of suppurative otitis media characterized

Researchers emphasize the importance of an early and accurate diagnosis of chronic suppurative otitis media followed by surgical therapy to prevent complications.

Study investigates prolonged pathological outcomes of traumatic brain injury

Researchers from the University of South Florida and colleagues at the James A. Haley Veterans' Hospital studying the long-term consequences of traumatic brain injury using rat models, have found that, overtime, TBI results in progressive brain deterioration characterized by elevated inflammation and suppressed cell regeneration.

Researchers show that protein p62 balances metabolism in fat tissue

In many cases, obesity is caused by more than just overeating and a lack of exercise. Something in the body goes haywire, causing it to store more fat and burn less energy. But what is it? Researchers at Sanford-Burnham Medical Research Institute have a new theory-a protein called p62.

Researchers find link between brain infections and climate in sub-Saharan Africa

The amount of rainfall affects the number of infant infections leading to hydrocephalus in Uganda, according to a team of researchers who are the first to demonstrate that these brain infections are linked to climate.

Researchers identify four new genetic regions associated with Behcet's disease

Researchers have identified four new regions on the human genome associated with Behcet's disease, a painful and potentially dangerous condition found predominantly in people with ancestors along the Silk Road.

Researchers discover new pathway to reduce paradoxical pain

For individuals with agonizing pain, it is a cruel blow when the gold-standard medication actually causes more pain. Adults and children whose pain gets worse when treated with morphine may be closer to a solution, based on research published in the January 6 on-line edition of Nature Neuroscience.

Link between Parkinson's and benomyl

For several years, neurologists at UCLA have been building a case that a link exists between pesticides and Parkinson's disease. To date, paraquat, maneb and ziram - common chemicals sprayed in California's Central Valley and elsewhere - have been tied to increases in the disease, not only among farmworkers but in individuals who simply lived or worked near fields and likely inhaled drifting particles.

Extensive white matter abnormalities in early schizophrenia

Patients with first-episode schizophrenia exhibit widespread white matter abnormalities, results from a brain imaging study show.

Paper provides comprehensive assessment of motor performance after cervical spinal cord injury

More than half of traumatic spinal cord injuries (SCI) in humans are cervical lesions, resulting in chronic loss of limb function. A better understanding of the link between the neurologic damage caused by SCI, spontaneous motor function recovery, and long-term motor deficits would lead to better therapeutic approaches, as discussed in an article in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
