Memories that can’t be recalled, but still influence us, surely have a close neighbour in those names or words that we know we know, but can’t quite bring to mind. For me, the name of a person or place can sometimes escape my grasp just as I am about to say it. That name is then “on the tip of my tongue”, but can’t be recalled for a while, often for a day or two, after I have slept on it. I have often thought this would be consistent with some connection being broken, or neurotransmitter depleted, by the attempted recall, which has then to be reconnected or replenished in the land of nod(28 June, p 19).
