Q

What is retention/encoding?

A

The perceived item of interest to be converted into a construct that can be stored in the brain. Requires consolidation to commit to longer memory.

Q

What is retrieval?

Q

What are the three types of implicit memory?

A

Procedural- skills and habits
Classical conditioning- emotional responses
Memory acquired through classical conditioning- emotional responsive and skeletal musculature.
Non-associative- acquired through habituation.

Q

What major area of the brain is important for processing of declarative memories and what structures does it include?

A

The temporal lobe:

  • Hippocampus
  • Subiculum
  • Parahippocampus
  • Rhinal cortical areas (e.g. pre-frontal cortex).
17
Q

What does the removal of structures responsible for formation of declarative memories result in?

A

Anterograde amnesia- inability to form new long term declarative memories.

18
Q

What structure is important for processing procedural memories, what structures does it include and what major brain structure is it part of?

A

Striatum, which includes the caudate nucleus and the putamen

- Part of the basal ganglia.

19
Q

What structure is important for formation of spatial memory? What are the cells important for spatial memory called?

A

Hippocampus- place cells and grid cells.

20
Q

What area of the brain is important for working memory?

A

The prefrontal cortex.

21
Q

True or false; working memory have unlimited storage duration and capacity?

A

False

22
Q

What is synaptic plasticity?

A

Ability of the synapse to change in strength in response to use or disused.

23
Q

What enzyme is activated during long term depression (LTD)?

A

Phosphatases- cause protein dephosphorylation.

24
Q

What enzyme is activated in long term potentiation?

A

Kinases- cause protein phosphorylation.

25
Q

True or false; the size of dendritic spine alters with the amount of use of a memory?

A

True- shrinks with LTD and enlarges with LTP.

26
Q

What is the most common form of dementia?

A

Alzheimer’s disease.
