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...

Different approach needed to protect brains of premature infants
A study of how the brain of a premature infant responds to injury has found vulnerabilities similar to those in the mature brain but also identified at least one significant difference, according to neuroscientists and neonatologists at Washington University School of Medicine in St. Louis. view more (2007-04-11)
Imaging technique sheds new light on the composition of the brain of moderate cannabis users
Diffusion tensor imaging, a newly developed magnetic resonance imaging technique, could enable researchers to gain a better understanding of the effects of cannabis on the brain. view more (2006-05-08)
Jury still out over risks of heading a soccer ball
Heading the ball in soccer is unlikely to cause brain injury but head to head collisions might, says a leading sports physician in this week’s BMJ. view more (2003-08-12)
A Window into the Brain
When we absorb new information, the human brain reshapes itself to store this newfound knowledge. But where exactly is the new knowledge kept, and how does that capacity to adapt reflect our risk for Alzheimer's disease and other forms of senile dementia later in our lives? view more (2009-08-13)
World's most powerful MRI ready to scan human brain
The world's most powerful medical magnetic resonance imaging machine, the 9.4 Tesla at the University of Illinois at Chicago, has successfully completed safety trials and may soon offer physicians a real-time view of biological processes in the human brain. view more (2007-12-05)
Brain changes in patients with migraine
Researchers from Harvard Medical School have found increased thickness of two areas of the brain cortex in people with migraine when compared to healthy controls. view more (2006-10-17)
New cannabis-like drugs could block pain without affecting brain, says study
A new type of drug could alleviate pain in a similar way to cannabis without affecting the brain, according to a new study published in the journal Pain on Monday 15 September. view more (2008-09-12)
VCU Study Shows Big-Brained People Are Smarter
People with bigger brains are smarter than their smaller-brained counterparts, according to a study conducted by a Virginia Commonwealth University researcher published in the journal "Intelligence." view more (2005-06-20)
Clue to genetic cause of fatal birth defect
A novel enzyme may play a major role in anencephaly, offering hope for a genetic test or even therapy for the rare fatal birth defect in which the brain fails to develop, according to a study from researchers at the University of Illinois at Chicago College of Medicine. view more (2008-10-10)
Me, My Left Brain and I: Recognising yourself and others
Whereas the right side of the brain seems to be used for identifying other people's faces, the left side of the brain is used when we recognise our own. Reports out from psychologists today suggest that this means the right side of the brain is used to perceive others and the left side of the brain is specialised for processing the self. view more (2004-04-19)
Possible genetic basis for alcohol abuse discovered
Alcoholism seems to have its roots at least partly in the genes. How genetic factors contribute to alcohol abuse is still an important question to be solved. There are hints that the body produces an opiate-active compound that may enhance alcohol addiction. New studies at the University of Bonn suggest that a gene is at least partly responsible... view more... (2001-04-18)
Traffic jam in brain causes schizophrenia symptoms
Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life. view more (2009-08-11)
Study on Joint Attention Has Implications for Understanding Autism
A hallmark of human nature is the ability to share information and to comprehend the thoughts and intentions of others. This capability involves social cognition (the cognitive processes involved in social interaction) and makes a significant contribution to the foundations for language development, as well as social competence. It also sets us... view more... (2007-09-27)
New radiation technique helps brain cancer patients keep their hair
Patients whose cancer has spread to the brain can avoid typical hair loss (alopecia) when treated with newer radiation techniques, thereby improving their quality of life while still controlling their cancer. view more (2005-10-17)
Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell. view more (2006-01-25)
Inflammation kills new brain cells
A research team at Lund University in Sweden attracted international attention a year ago by showing that new nerve cells can be generated in the brain after a stroke. However, most of these new nerve cells die rather soon. The same research team has now been able to show that an inflammation can lie behind the death of these new nerve cells,... view more...

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)
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)
Carnegie Mellon neuroscientist proposes new theory of brain flexibility
Carnegie Mellon University neuroscientist Marcel Just and Stanford postdoctoral fellow Sashank Varma have put forward a new computational theory of brain function that provides answers to one of the central questions of modern science: How does the human brain organize itself to give rise to complex cognitive tasks such as reading, problem solving... view more...
