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

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

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...

Scientists have shown that the brains of people with depression respond differently to feelings of guilt — even after their symptoms have subsided. University of Manchester researchers found that the brain scans of people with a history of depression differed in the regions associated with guilt and knowledge of socially acceptable behavior from individuals who never get depressed. The study — published in the journal Archives of General Psychiatry — provides the first...

Effect Of Acid In The Brain
2012-05-18 13:57:21

UI team develops new way to look at brain function University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too. "We are interested in the idea that pH might be changing in the functional brain because we've been hot on the...

(Ivanhoe Newswire) —Chewing fresh gum, thinking happy thoughts, taking deep breaths–they´re all ways we try and mentally distract ourselves from pain. New research shows there may be some truth behind these kooky pain-relieving tactics. The research is based on high-resolution spinal fMRI (functional magnetic resonance imaging). The findings showed as people experienced painful levels of heat, mental distractions actually inhibited the response to incoming pain signals at...

Mental distractions make pain easier to take, and those pain-relieving effects aren't just in your head, according to a report published online on May 17 in Current Biology, a Cell Press publication. The findings based on high-resolution spinal fMRI (functional magnetic resonance imaging) as people experienced painful levels of heat show that mental distractions actually inhibit the response to incoming pain signals at the earliest stage of central pain processing. "The results...
