    Study Notes

    Long-Term Memory and Amnesia

    • Long-term memory (LTM) can be divided into two broad categories: declarative and non-declarative memory.

    • Declarative memory refers to the conscious recollection of facts, events, and autobiographical knowledge, while non-declarative memory refers to changes in behavior without conscious recollection.

    • Declarative memory can be further divided into episodic and semantic memory, with episodic memory involving personally experienced events and semantic memory involving general knowledge about the world.

    • Non-declarative memory can be divided into procedural memory, classical and operant conditioning, and non-associative learning.

    • Tests of declarative memory are explicit, requiring conscious recollection, while tests of non-declarative memory are implicit, revealing memory processes indirectly through observed changes in behavior.

    • Amnesic patients provide support for the division between declarative and non-declarative memory, with selective deficits in memory processes seen in cases of amnesia.

    • Retrograde amnesia refers to an inability to remember knowledge acquired before brain injury, while anterograde amnesia refers to an inability to recall anything since the time of the injury.

    • Henry Gustav Molaison, or H.M., had both temporal lobes removed to treat epilepsy, resulting in dense anterograde amnesia and temporally graded retrograde amnesia.

    • H.M. was unable to form new long-term memories of new events or semantic knowledge, living in the past.

    • H.M.'s case provided evidence for the role of the medial temporal lobes, including the hippocampus, in the formation of semantic and episodic long-term memories.

    • Studies of other patients with lesions in their medial temporal lobe structures further support this assumption.

    • The distinction between declarative and non-declarative memory has important implications for understanding memory disorders and developing interventions.The Case of H.M.: Insights into Memory and the Role of the Hippocampus

    • H.M. suffered from severe anterograde amnesia and temporally-graded retrograde amnesia after bilateral hippocampal lesions in 1953.

    • H.M. had preserved short-term memory and general information acquired before the operation, but was severely impaired in consolidating and retrieving new episodic memories.

    • H.M.'s deficits were highly specific, indicating that STM/working memory does not depend on medial temporal lobe structures.

    • H.M.'s severe anterograde amnesia reveals an inability to form, retain, and retrieve new episodic and semantic memories.

    • H.M.'s retrograde amnesia was temporally graded, with greater difficulty remembering experiences closer to his surgery.

    • The preservation of H.M.'s remote episodic memories suggests that over time, some process appears to lodge information in memory so that it remains even after medial temporal lobe damage.

    • The medial temporal lobes, especially the hippocampi, are crucial for the consolidation of new declarative information, as demonstrated by H.M.'s deficits.

    • H.M. was able to form and retain non-declarative long-term memories, such as motor skills, demonstrating a dissociation between declarative and non-declarative long-term memory.

    • Patients with anterograde amnesia show preserved non-declarative memories, such as intact classical and operant conditioning and normal habituation and sensitization.

    • The preservation of non-declarative memory in anterograde amnesia suggests that the hippocampus is not necessary for all types of long-term memory.

    • The severe anterograde amnesia that results from removal of hippocampus bilaterally indicates that these structures must be crucial for the consolidation of new declarative information.

    • Further studies are needed to understand the additional process of consolidation, mediated by the hippocampus, that presumably proceeds automatically after the cognitive processes associated with depth and elaboration.
