Lecture 15 - Learning and Memory
Cards in this deck (38)
- 1Episodic memory is?conscious remembrance of events
- 2What is semantic memory?The remembrance of facts (conscious)
- 3What is declarative memory?'Knowing that'
- 4What is procedural memory?'Knowing how'
- 5Give and example of a procedural memory?Riding a bike
- 6What type of memory is help in the neocortex of the brian?Semantic (facts, objects etc)
- 7What type of memories reside in the hippocampus?Episodic (events)
- 8Where do procedural memories reside?Basal ganglia, cerebellum
- 9What are 3 non-declarative memory?1) Priming
2) Nonassociative learning paradigms
3) associative learning paradigms - 10Associative learning can be split into what 3 categories?1) classical conditioning
2)fear conditioning
3)operant conditioning - 11What is classical conditioning?Learning a relationship between 2 stimuli (cerebellum)
- 12What is an experiment used to test classical conditioning?Pavlov's Dog
- 13Learning a relationship between an organism's behavior and the consequences of that behavior is known as?Operant Conditioning
- 14What is imprinting?Instantaneous, non-conditioned form of learning
- 15An example of imprinting is?young animals learn the characteristics of the parent (filial imprinting)
- 16What are the 3 steps in the multi-stage memory model?1) Sensory memory
2)short term memory
3) long term memory - 17What is iconic memory and how long does it last?Visual sensory memory system, approx 0.5 secs
- 18What is echoic memory and how long does it last?auditory sensory memory system, lasts from 3-10secs
- 19What is the capacity of the short term memory?7 plus or minus 2
- 20How long does a unit remain in the short term memory?20-30secs
- 21What is retrograde amnesia?loss of memories (ability to learn is preserved
- 22Anterograde amnesia is?loss of the ability to form new memories and to learn (past memories preserved)
- 23What is the ability to learn dependent on?Hippocampus
- 24What are the affects of dementia?loss of memory, loss of the ability to learn, deterioration of language and other cognitive functions
- 25What causes Alzheimer's?the death of neurons in the hippocampus and entorhinal cortex
- 26What does the hippocampus interact with to form memories?neo-cortex
- 27What is Hebb's learning rule?synaptic strength is not constant and is not randomly assigned
- 28What are the two phenomena associated with long term potentiation?cooperativity and associativity
- 29What is an AMPA receptor permeable for?Na+
- 30What does an NMDA receptor depend on?Voltage
- 31NMDA receptors are blocked by what at rest?Mg2+
- 32What do NMPA receptors have a permeability for?Ca2+
- 33NMDA is said to act in a 'Hebbian-Manner, what does this mean?its detects presynaptic and postsynaptic activity simultaneously
- 34Define learningthe process of acquiring information
- 35Define memorystored, retrievable information
- 36What are the 4 processes of memory?1) Encoding
2) Storage
3) Retrieval
4) Reconsolidation/Updating/Forgetting - 37What is encoding?the conversion of information into usuable, 'processable' and 'storable' form
- 38What is reconsolidation?memory traces become labile when recalled
