Toxic Muskulinity: Muskox Are Injuring Their Brains During Ritual Headbutts
Scientists at the Icahn School of Medicine at Mount Sinai saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals—muskoxen and bighorn sheep.
Previously Unknown Function Identified for the Fragile X Protein
A new role for the fragile X protein has been identified in a new study that shows the protein can regulate a receptor in the memory center of the brain, influencing learning.
Can We Remember Moments Where Our Ego Dissolves?
People who practice intensive meditation report memories of states in which their sense of self dissolves. Is this at all possible?
Mapping Shows How the Brain Shrinks in Parkinson's Disease
A study has tracked the changes in brain volumes of Parkinson's patients over 8.8 years to provide a map of which parts of the brain change as the disease progresses.
Study Explores Statins as a Preventative Intervention for Depression
New research published in Biological Psychiatry examines the influence of statins on emotional bias, a marker for risk of depression. The researchers found that participants taking statins were less likely to recognize fearful/angry faces and more likely to report them as positive, suggesting they had reduced negative emotional bias.
Chimpanzee Calls Are More Like Human Language Than First Thought
Researchers recorded thousands of vocalisations from wild chimpanzees and found that the animals produced hundreds of different vocal sequences containing up to ten different call types. This structure may constitute a step towards human syntax.
First Potential Biomarker for Sudden Infant Death Syndrome Identified
A new study has identified a biomarker that could one day be used to help babies at higher risk of sudden infant death syndrome (SIDS).
Light Stimulation Spurs Neural Stem Cells and Cognition in Mice
Scientists at the UNC School of Medicine used optogenetic techniques to stimulate specific brain cells to increase production of neural stem cells and neurons relevant to memory and emotion processing in animal models.
How Electrical Stimulation Restores Balance to the Brain in Parkinson's
A computational model has been designed to understand how electrical stimulation suppresses abnormal brain rhythms in Parkinson's disease.
A Little Pressure Helps the Brain's Precursor Form
In the human embryo, the neural tube forms between the 22nd and 26th day of pregnancy. Later, the brain and spinal cord will develop from this tube. Researchers have now been able to show that the surrounding tissue is likely to play a significant role by exerting pressure from the outside.
