1

What is needed for long term memory?

Proteins

2

Involved in perceptual priming

Sensory systems

3

Protein kinases (PKM) prevents the removal or AMPA receptors. Lasts indefinitely

Maintenance (stage 4 of synaptic strengthening)

4

BDNF produces sustained calcium release. Protein synthesis contributes to stability. Lasts about 2-4 hours

Consolidation required (stage3 of synaptic strengthening)

5

What is the most beneficial way to prevent cognitive decline?

Social interaction and physical exercise as opposed to video games or isolated/stationary tasks

6

High amounts of this cause impairments in consolidation and retrieval

ACh

7

What happens in storage/consolidation?

Neural trace formed via synaptic plasticity across neurons and brain regions to form a physical representation of a memory

8

Learning new info

Encoding

9

What does increased activation of the hippocampus and parahippocampal gyrus predict?

Improved later remembering

11

Process of accessing stored memories (remembering)

Retrieval

12

Essential to memory functions and has differential effects in different stages of memory

Acetylcholine (ACh)

13

Parts of non declarative (implicit) memory

Procedural memory (how to), associative learning (conditioning), and non associative learning (habituation and sensitization)

14

Involved in conditioned responses between two stimuli

Cerebellum

15

What is less likely to be modified due to reconsolidation?

Strong, older memories

16

Patient HM cause of surgery

Severe temporal lobe epilepsy

17

Involved in habituation and sensitization

Reflex pathways

18

Has unlimited capacity and lasts indefinitely

Long term memory

19

Presynaptic differences in long term potentiation

More vesicles

20

Part of the brain involved with naming animals but not tools

Brocas area and left medial occipital lobe

21

Long term potentiation as a memory mechanism

Strongest link we have to memory formation. Associativity, cooperativity, and persistence

22

Parts of declarative (explicit) memory

Semantic (facts) and episodic (what happened)

23

What is contained in working memory?

A central executive, phonological loops, episodic buffers, and visuospatial sketchpads

24

What happens to most info that hits sensory memory?

It is forgotten

25

What two parts of the brain support the central executive in working memory?

Dorsolateral prefrontal cortex and anterior cingulate cortex

26

What are long lasting memories?

Stories we all have and like to tell that strengthen over time but aren't as accurate. Strongest memories as time goes on

27

What do a little and a lot of stress cause?

Little = boosted performance
Lot = reduced performance

28

What are the possible underlying changes that cause healthy aging of memory?

White matter deterioration, poor sleep quality, and difficulty clearing adenosine

29

What does memory retrieval stimulate?

Same consolidation processes responsible for original learning

30

Patient HM retrograde effect

Gradual episodic amnesia to about 10 years. More impaired closer to surgery
