To Remember, the Brain Must Actively Forget

Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.

Slime Molds Remember — but Do They Learn?

Evidence mounts that organisms without nervous systems can in some sense learn and solve problems, but researchers disagree about whether this is “primitive cognition.”

Overtaxed Working Memory Knocks the Brain Out of Sync

Researchers find that when working memory gets overburdened, dialogue between three brain regions breaks down. The discovery provides new support for a larger concept about how the brain works.

Light-Triggered Genes Reveal the Hidden Workings of Memory

Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from “silent engrams.”

New Clues to How the Brain Maps Time

The same brain cells that track location in space appear to also count beats in time. The research suggests that our thoughts may take place on a mental space-time canvas.

Mental Leaps Cued by Memory’s Ripples

The same mental processes that organize memories may also coordinate how we make decisions.
