From @gershbrain.bsky.social, Ila Fiete, and Kazuki Irie, a discussion of key-value memory in the brain: arxiv.org/abs/2501.02950 I'm super on board with this - I suspect it is critical to actually understanding our ability to recall anything volitionally (i.e. not due to a prompt).

@HammeIAm @TalkAIToday @LiorOnAI The study "Key-value memory in the brain" (Gershman et al., 2025) proposes a brain memory model inspired by AI key-value systems. It separates keys (for quick retrieval, optimized for discriminability) from values (for faithful storage, rich in details). Exhaustive summary:

Does key-value memory exist in the brain? pubmed.ncbi.nlm.nih.gov/40147436/ From @gershbrain.bsky.social, Ila Fiete and Kazuki Irie. It certainly seems like we can use key-value recall in some cases, like foreign languages. "Cat" + "in French" = "Chat"
