MRI perfusion imaging can help determine brain tumor progression

Gliomas, the most common malignant brain tumors in adults, can be difficult to treat because of their aggressive and invasive nature. In treating patients with gliomas, it is increasingly important that doctors be able to detect tumor changes early when there's a better chance for recovery.

MRI reveals microgravity-induced intracranial hypertension in astronauts

Magnetic resonance imaging (MRI) of the eyes and brains of 27 astronauts who have spent prolonged periods of time in space revealed optical abnormalities similar to those that can occur in intracranial hypertension of unknown cause, a potentially serious condition in which pressure builds within the skull.

Left hemisphere of the brain plays a critical role in creative thinking

It takes two to tango. Two hemispheres of your brain, that is. USC researchers are working to pin down the exact source of creativity in the brain - and have found that the left hemisphere of your brain, thought to be the logic and math portion, actually plays a critical role in creative thinking.

Memory training strategy can help patients with MCI

If someone has trouble remembering where the car keys or the cheese grater are, new research shows that a memory training strategy can help. Memory training can even re-engage the hippocampus, part of the brain critical for memory formation, the results suggest.

Exposure to deceptive advertising activates specific brain regions

Several specific regions of our brains are activated in a two-part process when we are exposed to deceptive advertising, according to new research conducted by a North Carolina State University professor. The work opens the door to further research that could help us understand how brain injury and aging may affect our susceptibility to fraud or misleading marketing.

Single dose of Ritalin may raise awareness of mistakes: Study

The study, by Dr Rob Hester from the Department of Psychological Sciences and colleagues at the Queensland Brain Institute, investigated how the brain monitors ongoing behavior for performance errors – specifically failures of impulse control. This study found that a single dose of methylphenidate (Ritalin) results in significantly greater activity in the brain’s error monitoring network and improved volunteers’ awareness of their mistakes.

CT scan as effective as MRI in predicting recurrent stroke risk

New research from the University of Calgary's Hotchkiss Brain Institute (HBI) shows that using a CT (computerised tomography) scan, doctors can predict if patients who have had a transient ischemic attack (TIA) or minor stroke, with neurological symptoms such as weakness or speech issues, are at risk for another more severe stroke.

MRI on the nanoscale closer to realty

Magnetic resonance imaging (MRI) on the nanoscale and the ever-elusive quantum computer are among the advancements edging closer toward the realm of possibility, and a new study co-authored by a UC Santa Barbara researcher may give both an extra nudge. The findings appear today in Science Express, an online version of the journal Science.

Patterns of brain development are distinct in infants with ASD

Patterns of brain development in the first two years of life are distinct in children who are later diagnosed with autism spectrum disorders (ASDs), according to researchers in a network funded by the National Institutes of Health. The study results show differences in brain structure at 6 months of age, the earliest such structural changes have been recorded in ASDs.
