So whenever a memory is being formed, any active cell for that particular memory will also have this light-sensitive switch installed in it so that we can control these cells by the flipping of a laser just like this one you see.
Så når som helst et minde bliver formet, vil enhver aktiv celle til det bestemte minde også have installeret denne lysfølsomme i sig så vi kan styre disse celler ved at skyde en laser ligesom den I kan se her.
