PSY30400 Chapter Notes - Chapter 7: Memory Consolidation
Chapter 7: Long Term-Memory – Encoding, Retrieval, and Consolidation
• Systems Consolidation:
o involves the gradual reorganization of neural circuits within the brain
▪ takes place over months/years
o Hippocampus =
▪ of extreme importance in forming new memories
• research needed to determine exactly how the hippocampus
responds to stimuli and how it participates in the process of
systems consolidation
o Standard Model of Consolidation:
▪ incoming information activates a number of areas in the cortex
• it is distributed because memories typically involve many sensory
and cognitive areas
▪ To handle this distribution, the cortex communicates with the
hippocampus, which then coordinates the activity of the different cortical
areas
▪ Reactivation:
• the major mechanism in consolidation
o process in which the hippocampus replays the neural
activity associated with memory
• Activity occurs in the network connecting the hippocampus to the
cortex
