PSYCH 120A Lecture Notes - Lecture 13: Temporal Lobe, Anterograde Amnesia, Memory Consolidation
Document Summary
Plays a critical role in the formation of new declarative memories. Receives info from other areas of the brain. Damage results in anterograde amnesia but nondeclarative knowledge can still be acquired. Details about your surroundings are dealt with by different parts of your brain. All of these areas that are involved in the experience send info to corresponding nodes of the hippocampus. Hippocampus binds info so that these different input are put together in one memory. Reactivates nodes in the hippocampus that send signals out to the cerebral cortex. Pattern completion: reactivation of nodes and cerebral cortex in response to stimulus relating to a memory. Over time, hippocampus" importance diminishes until it eventually is not needed. Consolidation: cortical connections link the memory but does not require hippocampus. Hippocampus activates nodes in a synchronous pattern then makes connections in the cortex closer so that the memory is consolidated the hippocampus is no longer needed. During sleep, the odor is presented again.
