What to know about head and brain MRI scans

Doctors use MRI scans to diagnose and monitor head injuries and to check for abnormalities in the head or brain. Magnetic resonance imaging (MRI) scans provide 3-D images of specific body parts. The scan produces highly detailed images from every angle. Depending on the purpose of the scan, a doctor ... Read More »

Building a better brain-in-a-dish, faster and cheaper

Writing in the current online issue of the journal Stem Cells and Development, researchers at University of California San Diego School of Medicine describe development of a rapid, cost-effective method to create human cortical organoids directly from primary cells. Experimental studies of developing human brain function are limited. Research involving ... Read More »

Common pesticide inhibits brain development in frogs

New research published in Environmental Toxicology & Chemistry reveals that low doses of a commonly used pesticide potentially harm the Northern Leopard frog by inhibiting their brain development. The pesticide chlorpyifos, which has been used since 1965 in both agricultural and non-agricultural areas, had clear effects on Northern Leopard tadpoles’ ... Read More »

Cannabis extract helps reset brain function in psychosis

Research from King’s College London has found that a single dose of the cannabis extract cannabidiol can help reduce brain function abnormalities seen in people with psychosis. Results from a new MRC-funded trial, published in JAMA Psychiatry, provide the first evidence of how cannabidiol acts in the brain to reduce ... Read More »

Scientists identify a new kind of human brain cell

One of the most intriguing questions about the human brain is also one of the most difficult for neuroscientists to answer: What sets our brains apart from those of other animals? “We really don’t understand what makes the human brain special,” said Ed Lein, Ph.D., Investigator at the Allen Institute ...

Secret tunnels discovered between the skull and the brain

Bone marrow, the spongy tissue inside most of our bones, produces red blood cells as well as immune cells that help fight off infections and heal injuries. According to a new study of mice and humans, tiny tunnels run from skull bone marrow to the lining of the brain and ... Read More »

Largest brain study of 62,454 scans identifies drivers of brain aging

In the largest known brain imaging study, scientists from Amen Clinics (Costa Mesa, CA), Google, John’s Hopkins University, University of California, Los Angeles and the University of California, San Francisco evaluated 62,454 brain SPECT (single photon emission computed tomography) scans of more than 30,000 individuals from 9 months old to ...

Learn music, new language to make your brain more efficient

In the study published in the journal Annals of the New York Academy of Sciences, individuals with either a musical or bilingual background activated different brain networks and showed less brain activity, researchers said. “These findings show that musicians and bilinguals require less effort to perform the same task, which ...

Fat accumulation in brain may point to Parkinson’s disease

The finding could have significant implications for identifying patients who may be at risk for developing Parkinson’s disease, and for the early treatment of the disease. Parkinson’s disease (PD) is a degenerative, progressive disorder characterised by the dramatic reduction of nerve cells, particularly dopamine neurons that are involved in movement ... Read More »
