What are the molecular underpinnings of memory storage? It makes sense that long term memories could be stored within subnuclear DNA modifications. This article makes it clear that we have no idea what transcriptional changes in individual neurons may provide the memory "code". The working code for recalling memories must be somehow presentable outside the nucleus within synapses of neurons though, or unique combinations of synaptic connections, otherwise memory recall would take too long. Once a memory is accessed, its still a long long chain of events between that and forming a thought, discerning between options, making a decision, and the follow through.
Very cool stuff. Kind of crazy to imagine your brain going through these elaborate motions storing useless information like "what the weather did yesterday" and "the dubious philosophical assumptions questioning the existence of free will" yet at the same time forgetting your neighbor's name for the 7th time.
