Episodic memory depends more heavily on some different (but related) brain regions (e. g. , hippocampus & anterior prefrontal cortex) as compared to semantic memory (e. g. , lateral temporal lobe and posterior prefrontal cortex).

The overly confident predictions of the 1950s had failed to take into account a subtle yet important fact: even the simplest acts of human comprehension require vast amounts of knowledge. For computers to understand, answer questions, or paraphrase, they needed this kind of knowledge base.
