- Carnegie Mellon University research shows how sensory-deprived brain compensates
04-17-2007 · EurekAlert!
Whiskers provide a mouse with essential information. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury.

- New neuroimaging study identifies 'brain signature' for cigarette cravings
12-18-2007 · EurekAlert!
A new brain imaging study by researchers in the Abramson Cancer Center of the University of Pennsylvania shows that cigarette cravings in smokers who are deprived of nicotine are linked with increased activation in specific regions of the brain. Using a novel method of measuring brain blood flow developed at Penn, this study is the first to show how abstinence from nicotine produces brain activation patterns that relate to urges to smoke.

- Mild head injuries increase risk of sleep disorders
04-02-2007 · EurekAlert!
A mild head injury can increase your chance of developing a sleep disorder, according to a study published in the April 3, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. Researchers say these findings highlight the need for improved diagnosis and treatment of sleep disorders in mild traumatic brain injury patients who complain of insomnia.

- New imaging technique identifies people-at-risk for Alzheimer's disease
12-20-2006 · EurekAlert!
UCLA researchers used innovative brain scan technology with a new imaging molecule, invented at UCLA, to show that abnormal brain protein deposits that define Alzheimer's disease can be detected in people with mild cognitive impairment, a condition affecting 15-20 million Americans that increases risk for developing Alzheimer's disease. The new imaging technique helped researchers track disease progression over a two-year period and may be helpful in detecting pre-Alzheimer's conditions.

- Researchers use novel three-dimensional imaging technique
10-24-2006 · EurekAlert!
Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus -- the area of the brain linked with memory -- in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. They found that three areas within the hippocampus of Alzheimer's patients show more atrophy compared with those in patients having amnestic mild cognitive impairment.

- Vision restoration therapy shown to improve brain activity in brain injured patients
08-14-2007 · EurekAlert!
Columbia University Medical Center researchers have demonstrated using functional magnetic resonance imaging, that brain activity was increased in stroke and traumatic brain injury survivors who underwent Vision Restoration Therapy, a rehabilitative treatment that helps these patients recover lost vision. The data will be published online in the peer-reviewed journal Neurorehabilitation and Neural Repair on Aug. 14, 2007.

- Research shows brain injury may occur within one millisecond after head hits car windshield
11-07-2006 · EurekAlert!
Center neurologist shows that brain injury may occur within one millisecond after a human head is thrust into a windshield in a car accident. This happens before any overall motion of the head following impact with the windshield and is a new concept to consider for doctors interested in traumatic brain injury.

- Low levels of neurotransmitter serotonin may perpetuate child abuse across generations
11-02-2006 · EurekAlert!
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low levels of serotonin are associated with anxiety and depression and impulsive aggression in both humans and monkeys.
