Brains keep temporary molecular records before making a lasting memory

To uncover how the brain keeps track of an animal’s experience, we started by asking how the brain records its electrical activity. Every experience you have, from chatting with a friend to smelling french fries, corresponds to its own unique pattern of electrical activity in the nervous system and brain. These activity patterns are defined by which neurons are active and in what way they’re active.
