Integrative Brain Function - Memory and Learning (round 1)

What are the 3 stages of memory?

sensory memory, working memory, long-term memory

How long does info stay in sensory memory?

1-3 seconds

How long does info stay in working memory?

up to 30 seconds

What system controls the flow of information in memory?

central executive system

What 3 memory stores support the central executive system?

phonological loop, visual sketchpad, episodic buffer

What is the function of the phonological loop?

translates visual info into auditory info

What is the function of the visual sketchpad?

hold images of objects in mind (visual/spatial info)

What is the function of the episodic buffer?

links working memory with long-term memory

How many items can we hold in the working memory?

7 (±2)

What are 3 types of long-term memory?

procedural, semantic, episodic

What is conditioning?

skill/emotional learning through deliberate, repeated practice

What brain regions are involved in declarative memory?

medial temporal lobe

What brain damage did Henry Molaison have?

damage to medial temporal lobe

What do short term changes in learning behaviour result from?

short term changes in some synaptic connections’ strengths which lead to changes in neurotransmitters release

What are 2 types of changes in synaptic efficiency in LTM?

long-term potentiation (LTP), long-term depression (LTD)

What is one of the most common signal pathways in eukaryotic cells?

cAMP/PKA
