It turns out our memories are sort of like (1) -they take time to (2) in our brain. In McGaugh’s experiment, rat A learns to find a clear platform in a tank and receives no medication. Rat B learns to find a clear platform and then receives a shot of adrenaline (3) afterwards. Rat C learns where the platform is and then receives an (4) of propranlol.

Adrenaline enhances our memories and hence we remember (8) and emotional events in our lives more than regular day-to-day experiences. Propranolol, however, sits on that (9) cells and (10) adrenaline. Adrenaline can be present, but it can’t do its job.
