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."

The neuroscientist Sheena Josselyn can evoke and erase memories in mice using new tools that precisely control the brain.

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.

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