Window into human behavior, brain disease seen in UCSF study
12-22-2006 · EurekAlert!UCSF scientists have identified a cell population that is a primary target of the degenerative brain disease known as frontotemporal dementia, which is as common as Alzheimer's disease in patients who develop dementia before age 65.

- High-quality marriages help to calm nerves
12-18-2006 · EurekAlert!
A University of Virginia neuroscientist has found that women under stress who hold their husbands' hands show signs of immediate relief, which can clearly be seen on their brain scans. "This is the first study of the neurological reactions to human touch in a threatening situation, and the first study to measure how the brain facilitates the health-enhancing properties of close social relationships," says Dr. James A. Coan.

- Replacing the cells lost in Parkinson disease
12-03-2007 · EurekAlert!
Parkinson disease is caused by the progressive degeneration of dopamine brain cells. Replacing these cells is considered a promising therapeutic strategy. Although DA cell-replacement therapy by transplantation of human fetal mesencephalic tissue has shown promise, limited tissue availability means other sources of these cells are needed. A recent study has described one new source for DA cells that provided marked benefit when transplanted into mice with a PD-like disease.

- Study outlines how stroke, head injury can increase risk of Alzheimer's disease
06-06-2007 · EurekAlert!
Researchers from the MassGeneral Institute for Neurodegenerative Disorders have discovered how the death of brain cells caused by a stroke or head injury may cause generation of amyloid-beta protein -- the key component of senile plaques seen in the brains of patients with Alzheimer's disease.

- Undergraduate research shows leaderless honeybee organizing
06-11-2007 · EurekAlert!
A new finding by an undergraduate scientist and a senior bee researcher gives new insight on the organization of honeybee colonies, which exhibit behavior rivaling human cultures in social complexity. The study reveals that major colony management activities are directed anonymously by hive workers using a nonspecific signal that modulates worker and queen behavior, and may have implications important for understanding other complex phenomena, from brain activity to terrorist networks.

- One shot of gene therapy spreads through brain in animal study
10-08-2007 · EurekAlert!
By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain—after one injection of gene therapy. If these results in animals can be realized in people, researchers may have a potential method for gene therapy to treat a host of rare but devastating congenital human neurological disorders, such as Tay-Sachs disease.

09-24-2007 · EurekAlert!
Now a team of researchers at the University of California, Santa Barbara has identified a nonconscious attention system, which still exists in the human brain, that maintains awareness of nonhuman animals and tracks changes in their location, behavior and trajectory.

- Study confirms imaging compound identifies amyloid-beta in human brain
03-12-2007 · EurekAlert!
A team led by Massachusetts General Hospital investigators has confirmed that the imaging agent Pittsburgh Compound B (PiB) binds to the protein in amyloid plaques that characterize Alzheimer's disease in the human brain. Their report describes the first postmortem neuropathological study of a dementia patient who had previously participated in a PET imaging study using PiB.

- First impressions: Computer model behaves like humans on visual categorization task
04-02-2007 · EurekAlert!
In a new MIT study, a computer model designed to mimic how the brain itself processes visual information performs as well as humans do on rapid categorization tasks. This study supports the hypothesis that rapid categorization happens without feedback from cognitive or other areas of the brain. The results also indicate that the model can help neuroscientists make predictions and drive new experiments to explore brain mechanisms involved in human visual perception, cognition and behavior.

- Ibuprofen restores learning ability in rats with liver failure
08-01-2007 · EurekAlert!
Cognitive impairment is one of the neurological effects in patients with hepatic encephalopathy (abnormal brain function due to severe liver disease). For the first time, a new study showed that treatment with an anti-inflammatory improves cognitive function in rats induced with chronic liver failure.
