The Uses of Memory in Olfactory Search, Antonio Celani Senior Researcher at ICTP, MaLGa Colloquia series, 20th February 2023 (this screenshot taken at 22min)
He uses a quote from Flatland, come on. The presenter, Antonio Celani, was a researcher for the French National Research Council (CNRS) in 2000 - and in 1999, CNRS had a European Symposium on Olfaction and Cognition.

Neuroscientists find that animals replay incidentally encoded episodic memories
Jan 2024, phys.org
(This breakthrough in neuroscience research expands on a 2018 study that first reported evidence that animals can replay past events)
Researchers gave nine rats a list of odors using many common household spices, like cinnamon and paprika. Then, the rats were given a memory assessment where they were presented with two scents from the previous list. The rats must then choose which scent was the third-to-last scent presented.placed rats in a radial maze where they were confronted with scented lids covering food. After the rats foraged through the maze, they were presented with the opportunity to report the third-to-last scent, having to draw from memory the previously presented scents.The rats remembered multiple pieces of putatively unimportant information and later replayed a stream of episodic memories when that information was needed to solve an unexpected problem. The first and only trial run ended with a 100 percent success rate."We remember information even though it was seemingly unimportant when it was encountered. When we happen to need that information, we replay the stream of events to identify the information needed to solve our current problem."
