Have you ever walked into a room and realised you can’t remember what you were looking for? We tend to do this more when we are thinking of a few things at once or doing two things at the same time.
Our brains create new memories, and forget old ones, by forging and breaking connections between nerve cells. Now researchers can do something similar using a light-sensitive electronic chip.
The only consciousness you can ever be certain about is your own. But there are different types of clues that could hint at what's happening within another entity.
Sports fans see it all the time: two people arguing about a split-second difference in who did what. New research suggests human beings have a bias to perceive their own actions as happening sooner.
Research milestones in the study of memory may help us find solutions to memory disorders like Alzheimer's or recovery from brain trauma.
If consciousness is a by-product of our brains' nonconscious processes, where does that leave us?
Blind people don't have superhuman ears but their brains can rewire themselves to give them an edge over those who can see.
Meaning and purpose aren't the same, but one does drive the other.
Study of the "memory centres" of the brain in adults offers hope for detecting Alzheimer's disease earlier -- before the onset of memory loss.
