Why can I remember waiting for the school bus in sweatpants and loafers (yes I was that kid) with a giant puffy jacket, watching chlorophyll depleted leaves spiral to the ground against an azure sky like it was yesterday; yet I can’t remember where I put my phone ten minutes ago? It’s short vs long term memory, and to turn short term memory into long term memory, obviously, takes time. The process is called “consolidation” and takes place primarily in the hippocampus (the region of your brain most responsible for memories). This article from Scientific American has a great overview of the process as well as some other theories on how we generate new memories, how we keep them, and how we lose them. So no matter where you put your phone, or what you wore to school in 3rd grade, remember to have a laugh and read more comics.
