      That was commonly thought to be the case, as your heart aches when you are very sad. But the heart is basically a pump for blood, and doesn’t have neurons that are responsible for thinking…

      My first thought on this was no, as it’s clearly the brain that holds all our memories.

      But it’s a good question (as it got me thinking) and there is a another organ that remembers, namely your immune system.

      When you get infected by some horrible little pathogen your immune system responds by recognising and destroying the invader. Interestingly it can remember all the pathogens you’ve previously fought against, so if you are infected with the same, or with a very similar, pathogen later on your body responds really quickly. This is of course the reason vaccines work.

      People also talk about muscle memory, where if you repeat a task enough time you develop procedural memory. Although it’s called muscle memory though it is really stored in the nervorus system and us controlled by the brain.
