> I think there is a strong cognitive bias in the present culture of thinking of the brain like a computer or hard drive. Good point. The behaviour observed is puzzling if your model says that the mice brains first train on the smell, then once is it learnt the memory becomes "locked in", and then later encounters with the smell are just read-only "recall and recognition" operations. Just like how we might modify a computer's memory and then later use the memory contents in a read-only way. But even as a layman on the subject, I can see that learning a smell and later trying to identify the same smell isn't two separate kinds of tasks. If I smell a rose for the 1000th time, I'm still learning about its smell. Why would a brain not change?
