Functional brain imaging in the dog.
Single photon emission tomography is an imaging modality using radiolabelled tracer substances to investigate function and metabolism of various organs in the living patient. We explored this technique in the dog to investigate brain function. Brain perfusion (an indirect indicator for metabolism and related brain function) was measured in normal... view more...

Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
Autism problems explained in new research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties. view more (2005-10-25)
Cholesterol-reducing drugs may lessen brain function, says ISU researcher
Research by an Iowa State University scientist suggests that cholesterol-reducing drugs known as statins may lessen brain function. view more (2009-02-24)
Link between Alzheimer's disease and traumatic brain damage clarified
This week scientists of the Flanders Interuniversity Institute for Biotechnology (VIB) will once again publish a breakthrough in their research regarding Alzheimer's disease. view more (2005-08-04)
Hepatic encephalopathy and prehepatic portal hypertension rat model
A research article to be published June 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team lead by Dr. Gabriela Beatriz Acosta, observed that the activity of GS was increased in the hippocampus in PH rats. view more (2009-06-29)
New insight into brain disorders
The function of an enzyme in the brain - strongly linked to a number of major brain diseases such as Alzheimer's, schizophrenia and bi-polar disorder - has been identified for the first time by researchers at the University of Bristol, UK. view more (2007-03-01)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
Human Brain Connectivity Mapping
The unique connectivity pattern of a brain region determines the type of information available to it, and hence influences its function. Defining these patterns enhances our knowledge of human brain architecture and function. Non-invasive in vivo definition of brain connectivity patterns complements functional imaging and provides new... view more... (2004-09-23)
Edinburgh researchers to probe memory loss in people with diabetics
Researchers at the University of Edinburgh are aiming to pinpoint why diabetes can cause memory loss and mental decline. A thousand people will take part in the study, the largest of its kind ever undertaken in the UK. view more (2006-06-27)
Exploring the function of sleep
Is sleep essential? Ask that question to a sleep-deprived new parent or a student who has just pulled an "all-nighter," and the answer will be a grouchy, "Of course!" view more (2008-08-26)
Children's National scientists uncover key developmental mechanisms of the amygdala
For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala-the part of the limbic system that impacts how the brain creates emotional memories and responses. view more (2009-01-13)
Violent video games leave teenagers emotionally aroused
A new study has found that adolescents who play violent video games may exhibit lingering effects on brain function, including increased activity in the region of the brain that governs emotional arousal and decreased activity in the brain's executive function, which is associated with control, focus and concentration. view more (2006-11-29)
Proteins in urine predict brain damage in laboratory animals
The study dealt with the development and prevention of strokes in particular rats which had spontaneously developed extremely high blood pressure. Such a high blood pressure level leads within a few weeks to damage to the kidneys, heart and brain such that the rats die. The researchers found that brain damage in these rats is always preceded by... view more... (1999-06-21)
Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor. view more (2009-06-23)
Why the brain has 'gray matter'
By borrowing mathematical tools from theoretical physics, scientists have recently developed a theory that explains why the brain tissue of humans and other vertebrates is segregated into the familiar "gray matter" and "white matter." view more (2006-01-12)
Anti-inflammatory drug blocks brain plaques
Brain destruction in Alzheimer's disease is caused by the build-up of a protein called amyloid beta in the brain, which triggers damaging inflammation and the destruction of nerve cells. view more (2008-06-24)
New study of hand-brain function offers insight into recovery for stroke survivors
A Queen's study of stroke survivors gives new insight into the stages of recovery of hand muscle control after a stroke, suggesting that patients may benefit from different treatment strategies at different times during the recovery process. view more (2006-05-17)
High-quality marriages help to calm nerves
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. view more (2006-12-19)
