Brain tumours in childhood

The first study of the lasting impact of these tumours -- the most common solid malignancies in childhood -- shows that survivors have ongoing cognitive problems.



Sex-based prenatal brain differences found

Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop.



Genetic defects and brain changes in schizophrenia

Researchers have found that the 22q11 gene deletion - a mutation that confers the highest known genetic risk for schizophrenia - is associated with changes in the development of the brain that ultimately affect how its circuit elements are assembled.



Exercise aids brain recovery

Exercise is a key factor in improving both memory and mood after whole-brain radiation treatments in rodents, according to data presented by Duke University scientists at the Society for Neuroscience meeting.



New brain stimulation treatment

Bilateral epidural prefrontal cortical stimulation (EpCS) was found generally safe and provided significant improvement of depressive symptoms in a small group of patients, according to researchers



Using Synthetic Evolution to Study the Brain

The human brain has evolved over millions of years to become a vast network of billions of neurons and synaptic connections. Understanding it is one of humankind’s greatest pursuits.



Gene controls number of brain cells

Recent finding suggests that a single gene, called GSK-3, controls the signals that determine how many neurons actually end up composing the brain. This has important implications for patients with neuropsychiatric illness.



A step toward better brain implants

Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan.



Balance organs affect brain blood flow

Researchers used a series of human centrifuge experiments to investigate the effects of stimulation of the otoliths and semi-circular canals on cerebrovascular response.



Changes in brain mechanisms for cocaine addicts

Researchers are utilising computational models to study how the brain's chemicals and synaptic mechanisms, or connections between neurons, react to cocaine addiction and what this could mean for future therapies.



Brain response food may aid weight loss

A difference in brain activity patterns may explain why some people are able to maintain a significant weight loss while others regain the weight, according to a new study.



Genetics: Missing protein leads to brain disorder

Researchers have successfully used protease inhibitors to restore to normal levels a key protein involved in early brain development.



Is Tetris good for the brain?

Brain imaging shows playing Tetris leads to a thicker cortex and may also increase brain efficiency, according to research published in the open access journal BMC Research Notes.



Concussions and brain tissue injury

Concussions, whether from an accident, sporting event, or combat, can lead to permanent loss of higher level mental processes.



Genetic variation linked to structural changes in the brain

An international group of researchers is the first to show that common variations in a gene are associated with differences in brain structure in both healthy individuals and patients with neurological and psychiatric disorders.



Brain innately separates objects for processing

For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain.



Medical news: A crystal ball for brain cancer?

Researchers have uncovered a new way to scan brain tumours and predict which ones will be shrunk by the drug Avastin - before the patient ever starts treatment.



Nanoparticles affect brain development in mice

Maternal exposure to nanoparticles of titanium dioxide affects the expression of genes related to the central nervous system in developing mice.



Genetics: Tracking impact of DNA damage on brain

Switching off a key DNA repair system in the developing nervous system is linked to smaller brain size as well as problems in brain structures vital to movement, memory and emotion.



Study supports brain power of fish in older people

Recently, there has been growing interest in whether dietary factors, particularly oily fish and meat, might influence the onset and/or severity of dementia.
