Q

What is the unitary view of declarative memory?

A

The view that the medial temporal hippocampal system provides support for both episodic and semantic memory, and damage to any of its areas affects both types equally

Q

What brain regions are in the medial temporal hippocampal system (MTH)?

A
  • Parahippocampal cortex
  • Hippocampus
  • Entorhinal cortex
  • Perirhinal cortex
  • Subiculum
22
Q

What is the modular view of declarative memory?

A

Only episodic memory requires the MTH

23
Q

According to the modular view, why does damage to the hippocampus not affect DNMS performance?

A

The surrounding perirhinal cortex was able to support familiarity-based recognition tasks

24
Q

Recollection-based recognition is associated with _____, while familiarity-based recognition is supported by _____

A
  • the hippocampus

- the perirhinal cortex

25
Q

Most research evidence supports the _____ view of declarative memory

A

Modular

26
Q

What are the two definitions of conscious recollection?

A
  • When you intentionally initiate a search of your memory

- When you have an awareness of remembering

27
Q

The feeling of remembering emerges when _____

A

A retrieved memory trace contains information about the time, place, or context of the experience that established the memory

28
Q

Representations of episodic memories are protected from ____

A

Interference

29
Q

What does the episodic memory system capture?

A

Information about the single events of our lives

30
Q

What are the two principles of the episodic memory system?

A
  • Its organization is hierarchical

- The circuit is a loop

31
Q

How does the episodic memory hierarchy work?

A

The level of memory integration increases as it flows from the neocortex to the hippocampus

32
Q

What brain areas are the first level of integration?

A

Perirhinal & parahippocampal cortices

33
Q

What brain area is the second level of integration?

A

Entorhinal cortex

34
Q

What brain area is the final level of integration?

A

Hippocampus

35
Q

Information is processed in the hippocampus and projected back to ____

A

The perirhinal & parahippocampal cortices

36
Q

What is the subiculum?

A

The region that projects information from the entorhinal cortex to the hippocampus (dentate gyrus/CA1)

37
Q

What is the hippocampal formation?

A

The hippocampus and subiculum

38
Q

The critical components of the MTH system are in the ____

A

Medial temporal lobes

39
Q

Information is ____ when it reaches the hippocampus

A

Amodal (neurons do not know whether information will be audio/visual/somatosensory)

40
Q

What is the last stage of information processing before the hippocampus?

A

The MTH system

41
Q

What is the indexing theory?

A

The hippocampus contains information about how to retrieve the memories stored in the neocortex

42
Q

What is pattern completion?

A

When a portion of the experience that originally established the memory activates/replays the entire experience

43
Q

What is pattern separation?

A

The segregation of similar representations in the neocortex

44
Q

What is the immediate shock effect?

A

If a rat is placed into a chamber and immediately shocked, it will not show fear of the chamber as it would if it were allowed to explore the chamber before being shocked

45
Q

Damage to the hippocampus in rats eliminates contextual _____

A

Preexposure

46
Q

Direct activation of the indexing neurons can produce _____

A

False memories

47
Q

Silencing indexing neurons prevents _____

A

Memory retrieval

48
Q

Engrams in the neocortex are controlled by the _____

A

Hippocampal index

49
Q

Why is it difficult to dissociate semantic from episodic memory in humans?

A

It is difficult to give someone a semantic memory without also having an episodic memory of the learning event

50
Q

What is a limitation of the indexing theory?

A

It does not account for how memories eventually do not rely on the hippocampus

51
Q

Pattern separation may occur _____

A

at the connection between the dentate gyrus and CA3
