As a supporting point, I think it's connected not only with mental functions, but also our senses.

I have a weak memory in general, but I always remember the most mundane things in my life that I had no idea I still contained in my brain, triggered by a specific smell.

Another example is that when I moved to a new street, while crossing one road, I stumbled upon the edge of tram road and almost fell. Two years and counting, my brain always brings this memory up while passing the same point on the road..
