Hippocampus moment

That moment you reach a place and realise exactly where you are. It reflects the moment where your hippocampus (the brain structure involved in memory and navigation which stores maps of the environment you have visited before) recognises that you have been to a place before and merges two cognitive maps together (one map made when you visited in the past and the map made in the present).

I am used to go to the supermarket by taking Broadway, but yesterday I was on South street and reached the supermarket. I had a hippocampus moment! I realised South street leads to broadway!
