Document Summary
Global anterograde amnesia: impaired memory for new info, seen on formal tests or everyday life. Mild temporally-graded retrograde amnesia: loss of memories up to 2/3years old at the time of the lesion. Procedure: bilateral removal of hippocampi to alleviate intractable epilepsy. Preserved cognitive abilities: non-declarative memory: procedural memory. **task: learned new motor skill mirror tracing: priming tasks (mostly temporal lobe, basal ganglion, and occipital lobe, classical conditioning, also . H. m. had terrible retrieval of long-term memory. Memories processed through hippocampus but stored in neocortex. Working memory h. m could repeat immediately a list of numbers. Impaired cognitive abilities: declarative memory given (limited size: cannot remember new episodic or semantic information, global anterograde amnesia, retrograde amnesia. Memory consolidation stabilizing a memory after encoding, turning it from stm to ltm groups of neurons fire together (uniformity) memories stored all across the brain storage-passive process of retaining information in the brain.
