Brain busy when we daydream

A new University of British Columbia study finds that our brains are much more active when we daydream than previously thought.



Keeping in rhythm good for brain

Recent research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning.



Making waves in the brain

Scientists have studied high-frequency brain waves, known as gamma oscillations, for more than 50 years, believing them crucial to consciousness, attention, learning and memory.



Seeing areas of the brain rarely seen

Radiologists are now able to look at parts of the brain using diffusion tensor imaging that are rarely visible with any other imaging method.



Autopilot Guides Proteins in Brain

Proteins go everywhere in the cell and do all sorts of work, but a fundamental question has eluded biologists: How do the proteins know where to go?



Brain metastases hijack neuron-supporting cells

Cancer that spreads to other organs finds a particularly inviting hideout in the brain, where these metastases are usually far harder to treat than they are in other locations.



First Aid for the brain

Research has shown that the regulator cytokine Interleukin 10 plays an important role in this protection, perhaps offering a new approach to stroke therapy.



Brain microbleeds in older adults

Individuals who take aspirin or other medications that prevent blood clotting by inhibiting the accumulation of platelets appear more likely to have tiny, asymptomatic areas of bleeding in the brain.



How the brain processes information

Researchers at UT Southwestern Medical Center have shed light on how the neurotransmitter dopamine helps brain cells process important information.



Brain cells have memory

Nerve cells in the V2 region are able to "grab onto" figure-ground information from visual images for several seconds, even after the images themselves are removed from our sight.



How brain responds to viral infection

Scientists have discovered that astrocytes respond to a molecule that mimics a viral infection using cellular machinery similar to that used by classical immune cells in the blood.



Rejuvenating brain cells with umbilical cord blood

When human umbilical cord blood cells were injected into aged laboratory animals, researchers found a subsequent rejuvenation of neural stem/progenitor cells.



Brain network complexity

A brain network linked to introspective tasks -- such as forming the self-image or understanding the motivations of others -- is less intricate and well-connected in children.



Rusty worms in the brain

Iron is vital to human life; for example, it is a component of haemoglobin, the substance that makes our blood red and supplies our cells with oxygen.



Peeking into the brain

Scientists devised a new experimental technique that produces some of the best functional images ever taken of the human brainstem, the most primitive area of the brain.



Tracing emotions in brain

First came direct marketing, then focus groups. Now, advertisers, with the help of neuroscientists, are closing in on the holy grail: mind reading.



Cocaine's effect on the brain

A study in mice shows that cocaine's effects may extend beyond the dopamine system and may involve the manipulation of the brain's metabolism.



Pain from the brain

Study reveals how people with a severe unexplained psychological illness have abnormal activity in the brain - New research from the University of Cambridge and UCL suggests that individuals with psychogenic disease, that is to say physical illness that stems from emotional or mental stresses, do have brains that function differently.



Brain damage can be measured after boxing match

An average of ten professional boxers died every year as the result of injuries in the 1900s. Retirement is often followed by memory problems, anxiety, dementia and other manifestations of brain damage. The degree to which the brain has been damaged can be measured and monitored after a match during the phase when it is particularly vulnerable to fresh injuries.



Nutrients in fish can boost brain development

The advice given to pregnant women over the consumption of fish rich in omega-3 fatty acids should be reconsidered after an international research project involving University of Ulster scientists suggested that polyunsaturated fatty acids in fish could actually be beneficial for child development.
