What we think we see isn’t always what’s really in front of us. Scientists use optical illusions to demonstrate how our brains use quick tricks to shape how we see the world.
Microbes in our gut (and our poop) can impact our brain and our behavior. Could we treat brain diseases and disorders by swapping “unhealthy” microbes for “healthy” ones?
Microglia are the brain’s immune cells, but what do they do when they’re not hunting down foreign bacteria or munching on debris in the brain? Can they even influence how you sleep?
