Stem cells reverse stroke damage and restore movement in mice
Source: All Top News -- ScienceDaily · Published
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help

REM sleep paradox: Dreaming may drain the brain’s energy even as fuel supply rises
Scientists discovered a surprising energy paradox in the brain during REM sleep, the stage most closely associated with dreaming. Blood supply to the brain begins increasing even before REM starts, but neurons’ immediately available energy, measured as ATP, then drops. The findin

When what you see doesn’t make sense, your brain does something remarkable
The brain may have a built-in way to quickly settle disagreements between regions processing the same scene. Researchers found that matching signals between two visual areas lasted longer, while conflicting signals rapidly faded away. This “consensus building” mechanism could hel
