Brain's timing linked with timescales of the natural visual world
Researchers have long attempted to unravel the cryptic code used by the neurons of the brain to represent our visual world. By studying the way the brain rapidly and precisely encodes natural visual events that occur on a slower timescale, a team of Harvard bioengineers and brain scientists from the State University of New York have moved one step... view more...

The immune system and Alzheimer's disease
Utrecht researchers, funded by NWO, have determined the role played by brain cells from the immune system that are located close to dying memory cells. The research will help determine the causes of Alzheimer's disease. In patients with Alzheimer's disease, the brain cells die off. The death of these neurones takes place primarily in the vicinity... view more... (2001-11-27)
Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see
Delving ever deeper into the intricate architecture of the brain, researchers at The Salk Institute have now described how two different types of nerve cells, called neurons, work together in tiny sub-networks to pass on just the right amount and the right kind of sensory information. view more (2005-10-24)
GEN reports on strategies to overcome blood-brain barrier
The blood-brain barrier (BBB) remains a major obstacle to the successful delivery of drugs to treat central nervous system (CNS) disorders, reports Genetic Engineering and Biotechnology News (GEN). view more (2009-02-06)
Stroke study sheds light on left-right brain divide
Research into the effects of strokes has furthered our understanding of the different roles of the left and right sides of our brains. view more (2007-06-11)
Stem cell research aims to tackle Parkinson's disease
Scientists in Sweden are developing new ways to grow brain cells in the laboratory that could one day be used to treat patients with Parkinson's disease, an international conference of biologists organised by the European Science Foundation (ESF) was told last week. view more (2008-01-21)
Antidepressants improve post-stroke 'thinking outside the box'
Antidepressant treatment appears to help stroke survivors with the kind of complex mental abilities often referred to as "thinking outside the box," according to a University of Iowa study. view more (2007-03-05)
Drug helps cognitive function in brain tumor patients after radiation
A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy. view more (2006-03-20)
Call for closer examination of 'brain death' as the end of life
The medical diagnosis of brain death is at odds with our traditional view of when death actually occurs. view more (2007-09-12)
Understanding mental illness through gene-environment interactions
Biological Psychiatry, published by Elsevier, is very pleased to present a special section of its February 1st issue devoted to fundamental new insights into epigenetics, a field of research devoted to understanding how the environment can produce long-lasting or even heritable changes in gene function without altering the DNA sequence. view more (2009-03-17)
Myelin suppresses plasticity in the mature brain
Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain. view more (2005-09-30)
Experts warn over health check brain scans
A new study has voiced concern about the growing market for brain screening tests, which people can buy as part of a general health MOT. view more (2009-09-04)
No increased risk of brain cancer from electromagnetic fields
Exposure to electromagnetic fields does not increase the risk of developing a brain tumour, finds a study of electricity industry workers, reported in Occupational and Environmental Medicine. Researchers from the Institute of Occupational Health at the University of Birmingham assessed causes of death among just under 84,000 workers employed in... view more... (2001-09-07)
Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells. view more (2006-02-17)
Insulin's brain impact links drugs and diabetes
Insulin, long known as an important regulator of blood glucose levels, now has a newly appreciated role in the brain. view more (2007-10-17)
Neurogenesis in the adult brain: The association with stress and depression
The brain is the key organ in the response to stress. Brain reactions determine what in the world is threatening and might be stressful for us, and regulate the stress responses that can be either adaptive or maladaptive. view more (2008-07-09)
Lack of happiness hormone serotonin in the brain causes impaired maternal behavior in mice
A lack of serotonin, commonly known as the "happiness hormone", in the brain slows the growth of mice after birth and is responsible for impaired maternal behavior later in life. view more (2009-06-24)
OHSU research reveals possible future target for delaying or stopping Alzheimer's
Researchers at Oregon Health & Science University's Neurological Sciences Institute (NSI) have located a possible target for future therapies aimed at delaying or stopping Alzheimer's disease. view more (2006-05-02)
Queen's expands testing for fetal alcohol syndrome
Improved technology, partnerships and collaboration across two provinces have allowed Queen's University scientists to dramatically expand the use of eye-movement tests that help identify and assess children with Fetal Alcohol Spectrum Disorder (FASD). view more (2009-03-20)
Oxygen deprived brains repaired and saved
Scientists from Melbourne's Howard Florey Institute have found special proteins that protect the brain after it has been damaged by a lack of oxygen, which occurs in conditions such as stroke, perinatal asphyxia, near-drowning and traumatic brain injury. view more (2006-08-25)
