What is semantic and episodic memory?

Semantic memory is focused on general knowledge about the world and includes facts, concepts, and ideas. Episodic memory, on the other hand, involves the recollection of particular life experiences.

Where are semantic memories?

The hippocampal areas are important to semantic memory's involvement with declarative memory. The left inferior prefrontal cortex (PFC) and the left posterior temporal areas are other areas involved in semantic memory use.

What is an example of semantic encoding?

Semantic encoding is processing where the meaning of information is encoded, instead of just the visual or auditory information. For example, a semantic encoding of words would involve rehearsal of their meanings, not just the way they look or sound.

What is semantic memory loss?

Semantic amnesia is a type of amnesia that affects semantic memory and is primarily manifested through difficulties with language use and acquisition, recall of facts and general knowledge. A patient with semantic amnesia would have damage to the temporal lobe.
