PET scan distinguishes Alzheimer's from other dementia

A PET scan (positron emission tomography) that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for Alzheimer's disease, a study led by a University of Utah dementia expert has found.

Harvard 'Brainbow' helps chart neural circuits

By activating multiple fluorescent proteins in neurons, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering their cells in a riotous spray of colors dubbed a "Brainbow."

Sound training rewires dyslexic children's brains for reading

Some children with dyslexia struggle to read because their brains aren't properly wired to process fast-changing sounds, according to a brain-imaging study published this month in the journal Restorative Neurology and Neuroscience (online October 16).

Step toward mapping the human decision-making process

The brain, the human supercomputer, might work more like an assembly line when recognizing objects, with a hierarchy of brain regions separately absorbing and processing information before a person realizes what they are seeing, according to new research conducted at the University of Pittsburgh and published in the Oct. 31 edition of the Journal of Neuroscience.

New brain marker predicts cognitive decline and the development of Alzheimer's disease

Duke University Medical Center researchers have used imaging technology to identify a new marker that may help identify those at greatest risk for cognitive decline and the development of Alzheimer's disease.

New insights into how the brain takes in and assembles stimuli from the outside world

The area of the brain that processes sounds entering the ears also appears to process stimulus entering the eyes, providing a novel explanation for why many viewers believe that ventriloquists have thrown their voices to the mouths of their dummies.

New magnetic separation 'traveling wave magnetophoresis' might detect multiple pathogens at once

A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads hundreds of times smaller than the period at the end of this sentence.

Diffusion tensor imaging shows structural changes in mild traumatic brain injury

Researchers report that diffusion tensor imaging can identify structural changes in the white matter of the brain that correlates to cognitive deficits even in patients with mild traumatic brain injury.

More evidence dopamine plays a role in obesity

A brain-imaging study of genetically obese rats conducted at the U.S. Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine - a brain chemical associated with reward, pleasure, movement, and motivation - plays a role in obesity.
