Study Notes
Learning and Memory: Trapped in the Eternal Now
- Patient H.M. (Henry Molaison) was a famous research subject in brain science
- Suffered from intractable epilepsy, seizures in both temporal lobes
- Neurosurgery in 1953 removing parts of the anterior temporal lobes on both sides
- Surgery relieved Epilepsy
- Lost the ability to form new memories (anterograde amnesia,)
- Could only briefly hold newly acquired information, then it vanished
- Could not form lasting relationships or retain events from after the surgery
- Couldn't remember his age, the current date, or events from before or after the surgery
- IQ remained average (above average but IQ tests don't require memory of facts for over a few minutes)
Two Major Types of Learning and Memory
- Distinctively human behaviors are learned
- Learning involves acquiring information and storing it in memory
- Memory is the process of storing and retrieving learned information
- Twentieth-century research shows fundamentally different types of memory
- Relying on varying networks of brain regions
- Clinical research and studies show varied memory impairments
- Two major types of memory: Declarative and Nondeclarative
Two Kinds of Memory
-
Declarative memory: conscious, explicit knowledge that you can describe/state to others - Episodic memory: personal memories - Semantic memory: general world knowledge, facts
-
Nondeclarative memory: procedural memory, shown by performance rather than by conscious recollection - Skill learning: motor skills - Priming: improved performance due to prior exposure to stimulus - Classical and operant conditioning: two types of associative learning
Medial Temporal Lobe Structures and Declarative Memory
- Medial temporal lobe (MTL) structures are important for declarative memory
- Specifically, the hippocampus plays a crucial role
- Damage to these areas can severely impair declarative memory
- Additional experiments showed the importance of the amygdala and perirhinal cortex, as well
Nondeclarative Memory and Different Brain Regions
- Skill acquisition: relies on basal ganglia
- Spatial memory: relies on hippocampus, especially for forming cognitive maps
- Emotional memories: AMYGDALA plays a crucial role
Memory Processes: Encoding, Consolidation, and Retrieval
- Encoding: processing of sensory input into memory
- Consolidation: durable storage of memories
- Retrieval: accessing stored memories
Long-Term Potentiation (LTP) in Hippocampus
- LTP is a strengthening of synaptic connections in the hippocampus
- Involves changes in the release and activity of glutamate
- Long-lasting and can be a cellular mechanism for memory
Adult Neurogenesis
- New neurons are generated in the brains of adult mammals
- Dentate gyrus of the hippocampus is a primary location
- Neurogenesis can enhance learning and memory
Aging and Memory
- Age profoundly impacts learning and memory processes
- Older adults often exhibit impairments in memory tasks involving conscious recollection. and require more effort to retrieve internal cues
- Autobiographical and semantic memories remain fairly stable in older age
