Neurobiologists restore youthful vigor to adult brains
May 18, 2015
UC Irvine researchers have successfully reactivated brain plasticity in the brains of adult mice. And in doing so, they've cleared a trail for further study that may lead to new treatments for developmental brain disorders such as autism and schizophrenia. Results of their study appear online in Neuron.
Single, low-magnitude electric pulse vagus nerve stimulation successfully fights inflammation
May 13, 2015
In a paper published by Bioelectronic Medicine, researchers explore how low-level electrical stimulation interacts with the body's nerves to reduce inflammation. The paper's findings indicate that activation of either motor or sensory vagus nerve bundles can diminish inflammation.
Study sheds new light on brain metabolism
Apr 24, 2015
New research published today in the journal Nature Communications represents a potentially fundamental shift in our understanding of how nerve cells in the brain generate the energy needed to function. The study finds that neurons, not astrocytes, are the primary consumers of glucose, and that consumption appears to correlate with brain activity.
Brain imaging changes in individuals with Down symdrome, may help advance Alzheimer trials
Apr 14, 2015
Researchers have characterized 3 different brain imaging changes in individuals with Down syndrome even before the onset of progressive memory and thinking problems. Their findings could help set the stage to evaluate promising treatments to slow down or prevent the onset of Alzheimer symptoms in these individuals, according to a study published in Alzheimer's & Dementia.
Characteristic pattern of protein deposits in brains of retired athletes who suffered concussions
Apr 06, 2015
A new UCLA study takes another step toward the early understanding of the degenerative brain condition chronic traumatic encephalopathy. Using a new imaging tool, researchers found a strikingly similar pattern of abnormal protein deposits in the brains of retired NFL players who suffered from concussions.
Researchers unravel mechanism that plays key role in sexual differentiation of brain
Mar 31, 2015
During prenatal development, the brains of most animals, including humans, develop specifically male or female characteristics. In most species, some portions of male and female brains are a different size, and may have a different number of neurons and synapses. However, scientists have known little about the details of how this differentiation occurs. Now, a new study by researchers at the University of Maryland School of Medicine has illuminated details about this process.
