The hippocampus soaks up important information from single experiences and events, says Matthew Wilson at the Massachusetts Institute of Technology. “If you get a nice big fat reward, you should be learning that the places you encountered along the way are all great places to be, and this trajectory is a good one.” ![]() Reliving a memory step-by-step in reverse could help the rat remember the first stages of what turned out to be a productive route, Foster says. When the researchers put four times as much chocolate at one end of the track, the rats mentally retraced their route there more often, and did this in a reverse pattern around twice as much as forward replays. They then let the rats run back and forth along a straight path with liquid chocolate at each end. To find out, they implanted electrodes into the hippocampi of five rats to measure the simultaneous activity of about 120 place cells in each animal. Reliving chocolateįoster and his team wondered if recalling memories backwards might help the rats keep track of where to find particularly good food. While forward replays intuitively make sense, figuring out why a rat would recall memories in reverse is more of a puzzle, Diba says. “This replay is very interesting and kind of mysterious,” says Kamran Diba at the University of Wisconsin in Milwaukee. ![]() He switched the control to the answer-play mode and waited for the tape to rewind.
