Document Summary
Memory: memories are what make human experiences meaningful, mental diseases are disordered emotional memories. Life experiences are coded in episodes: episodic memory: dementias are global losses in memory. Aging: dementia; alzheimer"s long term major loses in memory. When cortical systems are disrupted, we cannot reconstruct memories of our lives. Memory loss after injury: retrograde amnesia. Loss of memory after injury: anterograde amnesia. There are procedural memories that are explicit or implicit. Short- term (e. g. working) vs. long- term: all learned and remembered in separate brain areas: parallel systems. Types of long term memory: declarative: Frontal lobe: life history and plans: episodic memories: facts and verbal thoughts. Stored in frontal lobe (dorsal lateral cortex for episodic memories) More associated with left hemisphere and temporal lobe: semantic: associated with speech areas of left cortex. Left speech cortex: semantic memories front lobe and pre frontal lobe for planning. Habit learning cerebellum is important in reflex learning.
