What is the role of the hippocampus in memory?

The hippocampus binds semantic content to contextual information, providing a framework for organizing new events and predicting future events.

Who distinguished between episodic and semantic memory?

Endel Tulving.

How is episodic memory characterized?

Episodic memory is characterized as 'mental time travel', reflecting specific events associated with time and place.

What is semantic memory?

Semantic memory is general world knowledge that is stable and typically shared within a community.

What is the Hub and Spokes Model in semantic memory?

It describes how events are recalled in proper sequence with better relevant information remembered, using a central hub for main concepts and spokes for related concepts.

How does conceptual knowledge benefit memory?

More conceptual knowledge results in better memory for information overall.

What is the significance of the 'Episodic-Like' memory in scrub jays?

Scrub jays demonstrate episodic-like memory by remembering where they cached food and preferentially searching for them based on freshness.

What role does sleep play in memory consolidation?

Sleep helps in consolidating memories by replaying and integrating new memories with existing knowledge.

What is long-term potentiation (LTP)?

It is a process at the synapse level that strengthens synaptic connections, enhancing the efficiency of communication between neurons, crucial for forming long-term memories.

What happens to recent memories after hippocampal damage?

Recent memories become more vulnerable to disruption and cannot be recalled effectively.
