Document Summary
Episodic memory: representations of the past that are tied to a specific time and place (ex. event/episode, form of declarative memory. Conscious knowledge of the sources of the memory. Unaware of the source of the memory. Developmental amnesia: associated with hippocampal damage. Structural hippocampal damage was associated with inability to recreate image from memory, although perceptual abilities were fine. Medial temporal lobe (mtl: mtl = hippocampus + parahippocampal cortex, perirhinal cortex + entorhinal cortex (consolidation and retrieval, converging evidence from many lesion studies, and growing neuroimaging literature: Mtl plays important role in episodic memory. Hippocampus plays a specific role in binding perceptual information, and linking to a specific time and place. Study: paller and wagner: time 1, encoding. Present list of words to be remembered. Record bold response evoked by each word: time 2, retrieval. Which words are remembered vs forgotten: results. Based on activity in lateral pfc at encoding, can predict which words will be later successfully remembered.
