Scientists have uncovered an early brain mechanism that may help explain why people carrying the APOE4 gene face a higher risk of Alzheimer’s disease. For millions of people who carry the APOE4 gene, the strongest known genetic risk factor for Alzheimer’s disease, changes in brain activity may start years before memory problems become noticeable. Researchers [...]

A new study challenges the long-held idea that habits form only through slow, gradual repetition. What if your habits don’t form through countless repetitions over months or years? What if the brain can decide, almost instantly, that a behavior is no longer worth thinking about? That possibility is at the center of a new Johns [...]

Brain scans suggest long COVID’s biggest clues may lie in the brain’s emotion centers, not widespread inflammation. A new brain imaging study suggests that persistent symptoms of long COVID may not be driven by ongoing brain inflammation, as many researchers have suspected. Scientists in Finland used advanced imaging techniques to examine the brains of people [...]

Researchers suggest that old psychoanalytic ideas and modern brain science may be describing the same mental processes from different angles. More than a century after Sigmund Freud developed his influential theories of the mind, some researchers believe modern neuroscience may be arriving at surprisingly similar conclusions. A new paper published in the neurocognitive journal Entropy [...]

By tracking eye movements in zebrafish, researchers identified four different types of sleep, analogous to the complex sleep patterns of humans and other animals.

New research from the University of Oxford and the University of Reading suggests bipedalism and expanding brain size helped drive the overwhelming dominance of right-handedness in humans.
