• Resumen

  • A simple smell or sound can be enough to bring back memories of a place or person. Now it's possible to link unrelated memories, and separate them again -- in mice at least. Individual memories are stored in groups of neurons, an idea first proposed in 1949. To see whether two separate memories could be linked, Kaoru Inokuchi at the University of Toyama in Japan and colleagues taught mice to associate certain stimuli with pain. The team trained mice to form two separate fear memories. First, the mice learned to avoid the taste of saccharine. A few days later, the same mice were taught to associate a tone with a mild electric shock.
