1. Researchers trace early journey of modulating cells in brain Key cells in the brain region known as the hippocampus are formed in the base of the brain late in fetal life and undertake a long journey before reaching their final destination in the center of the brain shortly after birth, according to researchers at the National Institutes of Health....
2. Medicare: Researchers produce detailed map of gene activity in mouse brain A new atlas of gene expression in the mouse brain provides insight into how genes work in the outer part of the brain called the cerebral cortex. In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language....
3. Funded study shows pre-birth brain growth problems linked to autism Children with autism have more brain cells and heavier brains compared to typically developing children, according to researchers partly funded by the National Institutes of Health....
4. Autism blurs distinctions between brain regions Autism blurs the molecular differences that normally distinguish different brain regions, a new study suggests. Among more than 500 genes that are normally expressed at significantly different levels in the front versus the lower middle part of the brain’s outer mantle, or cortex, only 8 showed such differences in brains of people with autism, say […]...
5. Medicare: Funded twin study finds occupational chemical exposure may be linked to Parkinson’s risk A new research report contributes to the increasing evidence that repeated occupational exposure to certain chemical solvents raises the risk for Parkinson’s disease....
6. Researchers develop mouse with ‘off switch’ in key brain cell population NIH-funded scientists have developed a strain of mice with a built-in off switch that can selectively shut down the animals’ serotonin-producing cells, which make up a brain network controlling breathing, temperature regulation, and mood. The switch controls only the serotonin-producing cells, and does not affect any other cells in the animal’s brains or bodies....
7. Intervention Shows Promise in Treating Depression Among Preschoolers A new psychosocial approach shows promise in helping preschoolers with symptoms of depression function better and learn to regulate their emotions, according to an NIMH-funded study published online ahead of print October 31, 2011, in the Journal of Child Psychology and Psychiatry....
8. Medicare Information Psychopathic Traits Linked to Brain Reward System People who scored high on a test that measures impulsive and antisocial traits had exaggerated brain responses to certain “rewards,” like winning money or taking stimulant drugs. The new study provides evidence that a dysfunctional brain reward system may underlie vulnerability to a personality disorder known as psychopathy. ...
9. MedicareCard.com teaches kids about the power of the human brain Inquisitive students and their teachers from the Washington, D.C., area will explore the fascinating and multifaceted human brain at the 12th annual Brain Awareness Week celebration at the National Museum of Health and Medicine, Walter Reed Army Medical Center, on March 16 and 17. Students in grades 5 through 8 will engage in interactive activities […]...
10. Investigators discover new mechanism that may be important for learning and memory New findings in mice suggest that the timing when the neurotransmitter acetylcholine is released in the brain’s hippocampus may play a key role in regulating the strength of nerve cell connections, called synapses. Understanding the complex nature of neuronal signaling at synapses could lead to better understanding of learning and memory, and novel treatments for […]...
11. Medicare – Targeting the Blood-Brain Barrier, May Delay Progression of Alzheimer’s Disease Researchers may be one step closer to slowing the onset and progression of Alzheimer's disease. An animal study supported by the National Institute of Environmental Health Sciences (NIEHS), ...
12. Medicare, Deep Brain Stimulation, Two Different Targets, Produces Similar Motor Improvements in Parkinson’s Disease In a major study, investigators have compared how individuals with Parkinson’s disease respond to deep brain stimulation (DBS) at two different sites in the brain. Contrary to current belief, patients who received DBS at either site in the brain experienced comparable benefits for the motor symptoms of Parkinson’s....
13. Medicare: Same Genes Suspected in Both Depression and Bipolar Illness Researchers, for the first time, have pinpointed a genetic hotspot that confers risk for both bipolar disorder and depression. People with either of these mood disorders were significantly more likely to have risk versions of genes at this site than healthy controls...
14. Study ties blood protein to Alzheimer’s brain abnormalities Scientists are seeking ways to detect the earliest stages of Alzheimer’s disease, since harmful changes may be taking place in the brain years before symptoms appear. Now, researchers report that a blood test detecting a specific protein in blood samples from cognitively normal older people may reflect the levels of beta-amyloid protein in the brain […]...
