Memory Flashcards
What are 4 ways to consolidate a memory?
- Conscious rehearsal
- Unconscious rehearsal
- Practice
- Sleep (time)
Name two neuro-chemical learning processes. Explain them.
- Habituation: learning to ignore a noxious stimulus
- Sensitization: recovering/heightening responses for a harmful but habituated stimulus by pairing with a second noxious stimulus
Long term habituation is associated with a(n) ____ of synaptic density.
Long term sensitization is associated with a(n) ____ of synaptic density.
Long term habituation is associated with a(n) loss of synaptic density.
Long term sensitization is associated with a(n) increase of synaptic density.
What is Hebb’s postulate?
Neurons that fire together, wire together.
What is the difference between ontogenetic memory and phylogenetic memory?
Ontogenetic memory is the evolution of the organization of memory within an organism throughout its life.
Phylogenetic memory is the evolution of the organization of memory within a species across generations.
What are the two general types of memory for its qualitative classification?
Explicit (declarative) and implicit (nondeclarative).
What are the two forms of explicit memory? What are they respectively concerning?
- Episodic -> events
- Semantic -> facts
What are the three forms of implicit memory? Which one is resistant to aging and even to dementia?
- Priming -> resistant to aging and dementia
- Associative learning
- Procedural
What is a synonym to immediate memory?
Sensory memory.
What are the three forms of memory in the temporal classification of memory?
- Immediate
- Short-term memory
- Long-term memory
What is working memory? Are there limits to working memory?
Component of short-term memory that is processing all the information necessary to achieve a goal. Temporal and capacity limitations.
True or false: long-term memory is virtually limitless.
True.
What does allow memory consolidation?
To move memories from short-term to long-term by the progressive stabilization of theinitial memory “trace”.
What is an engram?
First interneuronal “talking” provoked by new information (first stage of consolidation) = first embodiment of memory = memory “trace”.
What are two biological processes that require the cellular stabilization of engrams?
- Protein synthesis
- Synaptic plasticity
