Topic: delayed Hebbian learning

How does the brain gain insight from limited novel experience? Humans and animals have a striking ability to learn relationships between items of experience, enabling structured generalization and rapid assimilation of new information. A fundamental type of such relational learning is order learning, which enables transitive inference: if A>B and B>C, then A>C. Remarkably, both humans and animals can quickly and globally reorganize separate learned orderings upon learning a single new item ("list-linking"; learn A>B>C and D>E>F, then C>D, and infer B>E), an instance of fast "reassembly" of exi
