It’s true that there is no single test that can diagnose Pans or Pandas, nor a biomarker that definitively signals their presence. Brain changes associated with these conditions are also so subtle that they don’t show up to the naked eye on imaging tests, Frankovich says. “When the radiologist reads the MRI, they’re looking with their eyeballs and they’re like, …

There are many ways to boost brain power, from exercising more often to learning new skills. But what about boosting the actual size of your brain? According to a new study, wearing the right kind of perfume or cologne can enlarge your brain’s gray matter. Researchers from Kyoto University and the University of Tsukuba in Japan asked 28 women to …

Big hands might mean big feet, but it seems long thumbs are linked to large brains – at least in primates. Researchers say the results suggest the brain co-evolved with manual dexterity in such mammals. “We imagine an evolutionary scenario in which a primate or human has become more intelligent, and with that comes the ability to think about action …

A single protein was found to fuel brain aging, and shutting it down reversed memory loss. Credit: Shutterstock Researchers at UC San Francisco have uncovered a surprising culprit in brain aging: a protein called FTL1. In aging mice, too much of this protein weakened memory and disrupted neural connections. But when scientists blocked FTL1, the mice’s brains regained youthful function, …

The brain’s map of the body in the primary somatosensory cortex remains unchanged after amputation.Credit: Zephyr/Science Photo Library A brain-imaging study of people with amputated arms has upended a long-standing belief: that the brain’s map of the body reorganizes itself to compensate for missing body parts. Previous research1 had suggested that neurons in the brain region holding this internal map, …

A persistent claim circulated online that woodpeckers avoid concussions from pecking because their long tongues wrap around their skulls, protecting their brains.  It’s true that some scientists in the past have believed the woodpecker’s long tongue provides some sort of inbuilt protection against brain damage due to frequent and impactful pecking.  However, peer-reviewed research in 2022 challenged this notion, using …

Summary: Researchers have identified a genetic region, HAR123, that may help explain what makes the human brain unique. Acting as a transcriptional enhancer, HAR123 influences the development of neural progenitor cells, which give rise to neurons and glial cells, and plays a role in determining their ratio. This regulation appears to support cognitive flexibility, a distinctly human trait involving the …
