Racial discrimination affects brain microstructure, study finds
'); document.write('A new study shows that the experience of racial discrimination affects the microstructure of the brain, as well as increasing the risk for health disorders.'); document.write('
Making a memory positive or negative
'); document.write('Researchers have discovered the molecule in the brain responsible for associating good or bad feelings with a memory. Their discovery paves the way for a better understanding of why some people are more likely to retain negative emotions than positive ones -- as can occur with anxiety, depression or post-traumatic stress disorder (PTSD).'); document.write('
No evidence that depression is caused by low serotonin levels, finds comprehensive review
'); document.write('After decades of study, there remains no clear evidence that serotonin levels or serotonin activity are responsible for depression, according to a major review of prior research.'); document.write('
Lymphatics help \'seed\' early brain cells in zebrafish
'); document.write('A recent article demonstrated how lymphatics -- which remove waste from the rest of the body -- are also associated with microglia and brain development in zebrafish.'); document.write('
When did the genetic variations that make us human emerge?
'); document.write('The study of the genomes of our closest relatives, the Neanderthals and Denisovans, has opened up new research paths that can broaden our understanding of the evolutionary history of Homo sapiens. A new study has made an estimation of the time when some of the genetic variants that characterize our species emerged. It does so by analyzing mutations that are very frequent in modern human populations, but not in these other species of archaic humans.'); document.write('
Vitamin B6 supplements could reduce anxiety and depression
'); document.write('Trial participants reported feeling less anxious or depressed after taking high doses of Vitamin B6 for a month. The trial provides evidence that the calming effect B6 has on the brain could make it effective in preventing or treating mood disorders.'); document.write('
Discovery advancing epilepsy research
'); document.write('A team of researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE).'); document.write('
Discovery of molecular signatures of immature neurons in human brain throughout life provide insights into brain plasticity
'); document.write('Researchers have used advanced techniques to show that, in a key memory region of the brain called the hippocampus, immature, plastic neurons are present in significant numbers throughout the human lifespan. The findings may resolve a long-running controversy over the existence of \'adult neurogenesis\'-- the production of new immature neurons in the mature human brain. The discovery also paves the way for the deeper study of adult neurogenesis and its roles in memory, mood, behavior, and brain disorders.'); document.write('
Brains of children with autism may not always \'see\' body language, study finds

Scientists reveal new evidence of key mechanism in Alzheimer\'s
'); document.write('Rutgers scientists have found more clear-cut evidence of how the destructive proteins linked to Alzheimer\'s disease attack human brain cells and destroy surrounding tissue.'); document.write('

Diagnosis of early-stage Parkinson\'s disease now possible with new method, researchers report
'); document.write('Cellular changes in Parkinson\'s could be revealed by adapting a related technique, known as quantitative MRI (qMRI). A new method enabled researchers to look at microstructures within the part of the deep brain known as the striatum -- an organ which is known to deteriorate during the progress of Parkinson\'s disease. With a novel method of analysis, biological changes in the cellar tissue of the striatum were clearly revealed and the team was able to demonstrate that these changes were associated with the early stages of Parkinson\'s and patients\' movement dysfunction.'); document.write('
Neuronal cell type for controlling the flow of information in the brain
'); document.write('Researchers have identified specific cells that regulate the transmission of information between brain areas. This discovery forms the basis for the development of new treatment options for neuropsychiatric disorders which are characterized by impaired coordination of information flow in the brain.'); document.write('
Whole blood exchange could offer disease-modifying therapy for Alzheimer\'s disease
'); document.write('A novel, disease-modifying therapy for Alzheimer\'s disease may involve the whole exchange of blood, which effectively decreased the formation of amyloid plaque in the brains of mice, according to a new study.'); document.write('
Wireless activation of targeted brain circuits in less than one second
'); document.write('Neuroengineers have created wireless technology to remotely activate brain circuits. Researchers showed they could control the behavior of freely moving fruit flies using magnetic signals that activated genetically engineered neurons causing the flies to perform specific behaviors.'); document.write('
