Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly. Results of the study were published online, August 13, by the Radiological Society of North America in the journal Radiology. Oak Brook, IL (PRWEB) August 13, 2012 Researchers at the Mayo Clinic...

Monkey Brains And Mind Control
2012-07-29 06:45:39

redOrbit Staff & Wire Reports - Your Universe Online Researchers have for the first time shown that they can control the behavior of monkeys by using pulses of blue light to very specific brain cells. This is an advance for optogenetics, a state-of-the-art method for making slight connectivity between brain activity and behavior. According to the researchers, similar light-based mind control could likely also be made to work in humans for therapeutic needs and care. "We are the...

In a genome-wide association (GWA) study, researchers from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) have identified several genes which influence degeneration of the hippocampus, the part of the brain most associated with Alzheimer disease (AD). The study, which currently appears online as a Rapid Communication in the Annals of Neurology, demonstrates the efficacy of endophenotypes for broadening the understanding of the genetic basis of and pathways leading to...

Patience And Self Control Illustrated In Brain Imaging
2012-06-19 09:04:54

Connie K. Ho for redOrbit.com Not taking a piece of chocolate cake is easy during the first ten minutes. However, trying to not take a piece of that same cake after 30 minutes is even more difficult. The reasoning behind this challenge is described in a new research project focused on patience and self-control. Scientists from the University of Iowa (UI) recently revealed that they discovered what the brain looks like when a person loses patience and self control with fMRI images. In...

Psychologists Reveal How Brain Performs 'Motor Chunking' Tasks
2012-06-12 15:29:40

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements. After dialing the number a few more times, you find yourself typing it out as a series of three successive bursts of movement: the area code, the first three numbers and then the last four numbers. Those three separate chunks allow you to type the...

Sleep Deprivation Linked To Food Choices, Elevated Anxiety Levels
2012-06-11 04:22:52

Using MRI scans, researchers have discovered how sleep deprivation can impact the parts of the brain where food-related choices are made, potentially explaining how obesity is linked to a lack of slumber. The study, which was presented at SLEEP 2012, the 26th annual meeting of the Associated Professional Sleep Societies (APSS), on Sunday, used functional magnetic resonance imaging (fMRI) to study the brain waves of 23 otherwise healthy adults, according to the American Academy of Sleep...

Researchers studying stroke patients have found a strong association between impairments in a network of the brain involved in emotional regulation and the severity of post-stroke depression. Results of the study are published online in the journal Radiology. "A third of patients surviving a stroke experience post-stroke depression (PSD)," said lead researcher Igor Sibon, M.D., Ph.D., professor of neurology at the University of Bordeaux in Bordeaux, France. "However, studies have failed to...
